#175 Issued on Saturday June 24, 2017 at 1300 UTC

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.

The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.

The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

Solar, Space & Geomagnetic Weather Conditions On

Friday June 23, 2017-

Solar activity was very low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 73.6 73.7 73.9.

The official daily sunspot number (SSN) was 22.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There were 2 newly risen and/or emerged official sun spot groups (SSG).

SSG #12662 located near N12W64 with a simple alpha magnetic signature.

SSG #12664 located near N17E36 with a simple alpha magnetic signature.

There was 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG) located near

S11E26.

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of

1 0 1 1 0 1 2 2.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

The 24 hour period maximum and minimum planetary A index (Ap) ranged between

7 and 2,

which was at quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.

The 24 hour period averaged background x-ray flux was at A8.03.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

-3.23 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -2 and +26 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

359 and 298 km/s.

There was a recurrent earth facing northern hemisphere coronal hole (CH), #809 (#805).

There was a recurrent earth facing southern hemisphere coronal hole (CH), #810 (#816).

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-

NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.

1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.

2.) A daily sunspot number of 150 or higher, 200 or higher best.

3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.

4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.

5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.

6.) Energetic protons no greater than 10 MeV (10+0).

7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.

8.) No current STRATWARM alert.

9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.

10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.

12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.

13.) Energetic electron flux levels no greater than 2 MeV (2+0).

14. A solar wind speed of less than 300 km/s for several days consecutively.

The Marconi legacy

Known as the ‘father’ of radio is Guglielmo Marconi. He died in July, 80 years ago. 

In the late 19th century Marconi was among a few keen people experimenting with waves that had been shown by German physicist Heinrich Rudolf Hertz. 

In honour of Hertz providing conclusive proof of the existence of electromagnetic waves , in 1960 ‘Hertz’ replaced the older ‘cycles per second’ in the International System of Units. 

Marconi read reports of Hertz in popular scientific journals, and had a vision that any two points on earth could communicate – an idea readily dismissed at the time. 

He remained convinced, having sent signals in late 1894 at his parent’s home. At 21-years of age in 1896, Marconi left for England with a system that could send Morse code signals across a room, which he called ‘wireless telegraphy’. 

In the WIA journal Amateur Radio magazine for July tells of the early days of Marconi through to his death on July 20, 1937.

It includes reference to vision of the Italian funeral procession for this scientific hero, and known influences in Australia of both Hertz and Marconi.

Average daily sunspot numbers rose this reporting week (June 15-21)
from 4.9 to 29.4. The previous week had four days with no sunspots,
and this week there were no zero sunspot days, hence the dramatic
increase in the average.

Average daily solar flux barely budged from 74.4 to 74.6

Average daily planetary A index went from 7.3 to 9.4, and
mid-latitude A index from 6.9 to 8.1.

Predicted solar flux is 75 on June 23-28, 74 on June 29 through July
4, 75 on July 5-7, 77 on July 8-9, 74 on July 10-14, 75 on July
15-17, then 74, 72 and 74 on July 18-20, 70 on July 21-23, 74 on
July 24-31, 75 on August 1-3 and 77 on August 4-5.

Predicted planetary A index is 12 on Jun 23-24, then 10 and 8 on
June 25-26, 5 on June 27 through July 12, then 20 and 12 on July
13-14, 10 on July 15-16, 5 on July 17-18, 8 on July 19, 12 on July
20-21, then 10 and 8 on July 22-23, then 5 on July 24 through August
6.

Geomagnetic activity forecast for the period June 23-July 18, 2017
from F.K. Janda, OK1HH.

"Geomagnetic field will be:
Quiet on June 27, July 4-5
Mostly quiet on June 28-29, July 1, 3, 7, 17
Quiet to unsettled June 26, July 2, 6, 12, 18
Quiet to active on June 25, 30, July 9-11, 15
Active to disturbed on June (23-24,) July (8,) 13-14, 16

"Amplifications of the solar wind from coronal holes are expected on
June (26-27), July (8,) 9-17, (18).

"Remark: - Parenthesis means lower probability of activity
enhancement and/or lower reliability of prediction.

"F. K. Janda, OK1HH"

This weekend is ARRL Field Day. Conditions should be good. Earlier
forecasts had the planetary A index this weekend at 5, but currently
for Saturday and Sunday it is 12 and 10, which is certainly
workable. Predicted solar flux is 75 for both days, better than
recent predictions for June 24-25.

6 meter report from George Hall, N2CG:

"On Father's Day 2017 there was a 6m Es opening from the US East
Coast to the Caribbean and Northern South America region that began
around 2145Z according to spots on the DX spotting Websites and
lasted for about two hours.

"I was returning home (Northern New Jersey FN20wv) after having
Father's Day dinner with my XYL and arrived around 7 PM EDT/2300Z.
Soon after I got on 6m and heard YV50ARV/6 in FJ78 on 50.125 MHz SSB
coming in 59+ and soon had him in my log. Over the next 45 minutes I
worked the following exchanging 59/599 signal reports both ways:

"YV5IUA in FK60 on SSB, PV8ADI in FJ92 on CW, KP4JRS in FK68 on CW,
WP2B in FK77 on CW, and KP4EIT in FK68 on SSB.

"Looking at the DX spots being posted during this opening I counted
about 80 percent JT digital mode spots versus 20 percent SSB/CW mode
spots. Last year during a typical 6m Es opening this was the exact
opposite with about 80 percent SSB/CW spots versus 20 percent JT
digital mode spots being reported.

"So it looks like the JT digital modes have made a very strong and
dominant role on working 6m DX and in such a short period of time.
If the JT digital modes can evolve with faster turnaround times
(like what was recently reported on the WSJT-X reflector); then we
may see 6m DX activity become almost exclusively fast turnaround JT
digital modes and 'the way to go mode to work 6m DX.'"

Propagation News – 25 June 2017

Last week the solar flux index remained steadfastly in the mid-70s. There was only one very minor S class solar flare, on Sunday, 18 June. As predicted, geomagnetic conditions were unsettled on the Sunday, but improved as the week went on.

During a week when we had the solar solstice, HF conditions were subdued. This is pretty much par for the course this time of year. A change in the ionospheric chemistry with more diatomic molecules and fewer monatomic species means it is harder to ionise. So, paradoxically, despite having more sunlight, maximum useable frequencies are lower during summer days. But, as we keep saying, you may find that 20m remains open much later in the evening. If we had some sunspots it might have even remained open all night.

Next week NOAA predicts more of the same with the solar flux index in the range 70-74. Monday may be a little unsettled geomagnetically, but then the rest of the week should be better with a K-index of around two.

At the moment, maximum useable frequencies over a 3,000km path are around 14MHz, with occasional openings up to 18MHz. After dark, 30m and 40m will remain the best bands for DX, with 20m probably closing in the late evening and usually before midnight. Sporadic E openings on the higher bands should also remain prevalent as we head towards the end of June.

VHF and up:

Sporadic E is still the main DX mode through to August, and on 16 June we had one of the best events for a long time. Thousands of 144MHz QSOs were reported to Make More Miles on VHF, including contacts from South Wales into the Balkans.

The best policy to catch sporadic E is to maximise your chances by checking the bands late morning and late afternoon or early evening to capture the traditional two peaks of activity. Also look for late evening openings towards Iceland, Greenland and beyond. Check the beacons and clusters for signs of activity, remembering that an opening will build up in frequency as it develops—first 10m, then through 6m and 4m, to perhaps 2m.

Despite the heatwave, tropo conditions didn’t seem to materialise last week, with no cluster reports of 144MHz or above tropo QSOs over 600km from the UK.

Over the next week or so, it looks as if the changeover to low pressure will be completed and for much of the time there will be low pressure over Britain or nearby. This means that rain scatter will be the best GHz bands DX option. Tropo will not feature strongly again this week, but some short-lived overnight and dawn lifts are possible before the heat of the day breaks down any surface temperature inversion.


Today shows high and falling Moon declination, with low and increasing losses, so get your EME QSOs in the early part of the coming week.

#174 Issued on Friday June 23, 2017 at 1400 UTC

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation conditions are in a steady state but may begin deteriorating in the next day or so.

HAMATEUR & SW BROADCAST HF BANDS-

NORTHERN HEMISPHERE RADIO WAVE PROPAGATION
80-60 (75-60) meters- poor to fair at night and very poor at day,

40-30 (41-25) meters- fair to good at night and poor at day,

20-17 (22-15) meters- fair to good at night and poor to fair at day,

15 (13) meters- very poor at night and poor to fair at day,

12(11) meters- very poor at night and poor at day.

10 (11) meters- very poor at night and very poor at day.


SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-

80-60 (75-60) meters- good at night and poor at day,

40-30 (41-25) meters- good at night and fair at day,

20-17 (22-15) meters- very poor at night and good at day,

15 (13) meters- very poor at night and fair to good at day,

12 (11) meters- very poor at night and fair at day.

10 (11) meters- very poor at night and poor at day.

Received RF signal strength scale-

Very Good- +1 over S9 Or Greater
Good- S7-9

This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.

The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.

The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

Solar, Space & Geomagnetic Weather Conditions On

Thursday June 22, 2017-

Solar activity was very low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 74.4 73.7 74.3.

The official daily sunspot number (SSN) was 23.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There were 2 newly risen and/or emerged official sun spot groups (SSG).

SSG #12662 located near N12W50 with a simple alpha magnetic signature.

SSG #12664 located near N17E49 with a simple alpha magnetic signature.

There was no unofficial and as of yet unnumbered earth facing sunspot group (SSG).

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of

2 1 0 0 0 0 2 1.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

The 24 hour period maximum and minimum planetary A index (Ap) ranged between

7 and 2,

which was at quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.

The 24 hour period averaged background x-ray flux was at A7.11.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

+3.48 nT north.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -15 and 26 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

346 and 282 km/s.

There was a recurrent directly earth facing (geoeffective) northern hemisphere coronal hole (CH), #809 (#805).

There was a recurrent southern hemisphere coronal hole (CH), #810 (#816).

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-

NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.

1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.

2.) A daily sunspot number of 150 or higher, 200 or higher best.

3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.

4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.

5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.

6.) Energetic protons no greater than 10 MeV (10+0).

7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.

8.) No current STRATWARM alert.

9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.

10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.

12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.

13.) Energetic electron flux levels no greater than 2 MeV (2+0).

14. A solar wind speed of less than 300 km/s for several days consecutively.

Glenn Hauser logs June 21-22-23, 2017

** ALASKA. 11885, June 22 at 1230, no signal from KNLS, and JBA carrier on 11870 during English hour. Some days 11885 is in use instead of 7355, some not; you never know which it will be, and from so far north there are wide variations in propagation (Glenn Hauser, OK, WORLD OF RADIO 1883, DX LISTENING DIGEST)

** ANTARCTICA [non]. 5985, June 21 at 2150 check, VG signal from BBCWS mid-winter special, Woofferton site as heard via UTwente SDR in Netherlands, family greeting. Didn`t even try for it direct here on any of three frequencies. Richard Langley, NB, will be archiving his recording of the whole thing, accessible to DXLD yg members (Glenn Hauser, OK, WORLD OF RADIO 1883, DX LISTENING DIGEST)

** ARGENTINA [non]. 11580, June 22 at 2210 check, RAE in Spanish instead of Italian --- but at least speaking with an Italian accent. 5950 which is announced as the only Spanish frequency, far too weak JBA carrier here to compare. Later I`m wondering if it was really Italian service as supposed to be, but with bits in Spanish?

7730, June 23 at 0602, RAE via WRMI already playing tango music rather than news, 0605 Japanese announcement.

11580, June 23 at 1425 check past 1448, WRMI is playing World Music, including familiar ME tunes, no announcements, rather than RAE in Spanish. This hour on the WRMI skedgrid never got labeled RAE Spanish, but had been such whenever checked all month, Monday-Saturday. Presumably a bonus, and maybe defaulted to WM which occupied this hour previously, if there was a missing file for today; or canceled? Only time will tell (Glenn Hauser, OK, DX LISTENING DIGEST)

** BENIN. 1566, June 23 at 0446, JBA carrier still at 0502, presumed TWR. Even weaker than when I heard it June 21 at 0353-0412. On globe I refine the true bearing to 76 degrees; Parakou is slightly north of central Benin. If this carrier is audible in Oklahoma and AB/BC, it may well be heard all over North America; go for it! (Glenn Hauser, OK, DX LISTENING DIGEST)

** BRAZIL. 4885.02, June 23 at 0206, JBA carrier vs hi QRN level; also at 0451 when I measure it slightly on hi side, and still at 0558.

Rádio Clube do Pará, Belém, had been the strongest and most reliable ZY on 60m, and usually on all night, but on June 19 there were reports in the radioescutas group that station had been off the air since June 16 as it was facing fines of 50 kiloreais per day, in some kind of complicated political dispute about who really controls the station.

4885 is one of those frequencies with more than one Brazilian tropical station, the other being Rdif. Acreana, Rio Branco, with nominal sked in WRTH 2017 as 0900-0400, but both were double-daggered as inactive. So am I hearing its carrier now, or is Pará coming back? Suspect the latter, as both Dave Valko and Anker Petersen had previously reported Pará on 4885.02 (Glenn Hauser, OK, DX LISTENING DIGEST)

** BRAZIL. 11857.39vv, June 22 at 0551, JBM signal presumed R. Aparecida, which is varying more widely now, and won`t settle down as I try to measure it (Glenn Hauser, OK, DX LISTENING DIGEST)

** BRAZIL. 11934.930, June 22 at 0553, soft music, 0555 full ID with SW frequencies, claiming 24-hour service, except I can`t catch the name. Rudolf Grimm, Brasil, says it`s no longer called Rádio RB2, but Rádio Evangelizar. Also applies to 9725- and 6040+ from Curitiba (Glenn Hauser, OK, DX LISTENING DIGEST)

** CANADA. 2749-USB, June 23 at 0449, VP robotic talk, can`t even be sure of language in noise level, but could well be French. Same audible slightly weaker on 2598-USB. Canadian Coastguard schedule as in DXLD 16-43 shows both as VCF Les Escoumins, QC, from two different QC transmitter sites, Natashquan on 2598 and La Vernière on 2749, both with their final transmissions starting at 0437, not resuming until 0847 (tho other stations are back from 0737/0740) (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 5025, June 23 at 0453, R. Rebelde is on at S9+30 but just barely modulated. By 0600 still undermodulated but better, with resounding timesignal ending 32 seconds late (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1882 monitoring: confirmed Wednesday June 21 at 2114, the 2100 broadcast on WBCQ 7490.1v-AM, poor S6. Also confirmed Wednesday June 21 at 2330 on WBCQ, 9330.20v-CUSB, fair.

`Radio Libertad` is now only at 2330-2400 M-F and sure to be jammed. But preceding it now at 2315-2330 M-F is a `Noticiero`, but from what source? Will need to try to hear it, probably on unjammed webcast. Some other local produxions on 9955, presumably by Cuban exiles:

UNIDENTIFIED. 6055, June 22 at 0056, another check for the unID VP signal I had previously; now there are sporadic carriers spuriously out of the very strong 6060 Habana transmitter, in addition to its incessant splash. But the first unID was quite different, continuous: ``6055, June 18 at 0048, JBA signal with talk, where there is normally nothing. What could it be?`` (Glenn Hauser, OK, DX LISTENING DIGEST)

#173 Issued on Thursday June 22, 2017 at 1600 UTC

We are now firmly in summer/winter solstice type of HF radio wave propagation conditions.

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstice.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation conditions are improving but may begin deteriorating in the next 1-2 days.

40-30 (41-25) meters- fair to good at night and poor at day,

20-17 (22-15) meters- fair to good at night and poor to fair at day,

This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25 watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts and ½ wave dipole up at 40 feet.

The hamateur radio SSB RF mode signal levels received are based on 100 watts and ½ wave dipole up at 40 feet.

The HF shortwave broadcast band AM Mode RF signal levels are based on 100,000 watts (100 kw) and a typical VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

---------------------------------------------------------------------------------------------

Solar, Space & Geomagnetic Weather Conditions On

Wednesday June 21, 2017-

Solar activity was low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 74.1 73.7 73.8.

The official daily sunspot number (SSN) was 35.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now unusually early.

In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.

As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.

In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There were 3 newly risen and/or emerged official sun spot groups (SSG).

SSG #12662 located near N12W37 with a simple alpha magnetic signature.

SSG #12663 located near N14W85 with a simple alpha magnetic signature that was in the process of setting around the west limb of the sun.

SSG #12664 located near N13E62 with a simple alpha magnetic signature.

There was no unofficial and as of yet unnumbered earth facing sunspot group (SSG).

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of

0 0 0 1 1 1 1 2.

The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.

The 24 hour period maximum and minimum planetary A index (Ap) ranged between

7 and 0,

which was at quiet geomagnetic conditions.

The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level below 10 MeV.

The 24 hour period averaged background x-ray flux was at B1.55.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

+4.55 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -17 and +9 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

368 and 255 km/s.

There was a directly earth facing (geoeffective) northern hemisphere coronal hole (CH), #809. It had grown southward and could possibly impact earth’s geomagnetic field in a negative manner in 1-2 days.

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL HF PROPAGATION CONDITIONS-

NOTE!!! The propagation indices "interpretations" are my personal
intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted © 1988-2017 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.

1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.

2.) A daily sunspot number of 150 or higher, 200 or higher best.

3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.

4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.

5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.

6.) Energetic protons no greater than 10 MeV (10+0).

7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.

8.) No current STRATWARM alert.

9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.

10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.

12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.

13.) Energetic electron flux levels no greater than 2 MeV (2+0).

14. A solar wind speed of less than 300 km/s for several days consecutively.

Automotive industry embraces DAB+ radio

Over 4.6 million new cars with DAB sold in 2016, across eight key European markets and Australia 21 June 2017, Munich, Germany: Today in Munich at the 2017 WorldDAB Automotive event, speakers from automotive manufacturers, regulators and the broadcast industry gathered to discuss the growing adoption of DAB radio in the car.  

The event also saw the announcement of results from research WorldDAB and its members have undertaken into the digital radio user experience in cars, a first of its kind study.  

The adoption of DAB radio in cars :

In 2016, 4.6 million new cars were sold with DAB across Germany, France, the UK, Italy, the Netherlands, Norway, Switzerland Denmark and Australia – up nearly 40% on 2015.  
In Norway 98% of new cars are fitted with DAB as standard, with the UK at 87% and Switzerland at 66% all three markets are leading the push for drivers to go digital. In the second wave of European markets, Denmark, France, Germany, Italy and the Netherlands, DAB is fitted as standard in a growing number of vehicles. 

“With Norway in the process of switching off national FM services and Switzerland starting its Digital Switchover in 2020, it’s more important than ever for the automotive industry to fully embrace DAB radio,” said Patrick Hannon, President, WorldDAB. “Our message to the automotive industry today is that all cars should have both FM and digital radio capabilities, delivering the best experience for drivers across the continent.”   

Across Europe there is a growing recognition by national and European policymakers, media regulators and public and commercial broadcasters that DAB digital radio is the future core platform for radio. 

Speaking on behalf of the European Digital Radio Association, Helwin Lesch, EDRA Board Member said:   

“Drivers should be able to listen to their favourite stations on the move and across borders. Our members represent over 300 stations that reach more than 130 million people each day and it’s clear that DAB digital radio is the core future platform for radio. Our members and the automotive industry continue to work together on delivering the best possible experience to drivers across Europe. As DAB becomes the natural choice for consumers we want Europe to embrace it and manufacturers to offer DAB alongside FM in sets and vehicles, just as they did for AM and FM, and at a price which is attractive to the consumer." 

German highlights: 

The event saw a particular focus on developments in Germany.  Population coverage has now hit 96% and in February 2017, Dorothee Bär, Parliamentary State Secretary to the Federal Minister for Transport and Digital Infrastructure, published the Digital Radio Action Plan.
