Results of the Low Band VHF Propagation Tests - Sat 13th & Sun 14th May 2023

Over the last few months, Phil EI9KP in the west of Ireland has been carrying out some low-band VHF propagation tests. On the 13th & 14th of May 2023, he had a beacon action at 32 MHz, 34 MHz and 36 MHz.

This is his report...

Local reports: EI3GYB Michael in IO53OT (30kms) reports receiving the beacon on all three frequencies, signal strength from 5/1 to 5/3 for the CW component.  He was using an ICOM IC-7200 and a horizontal V antenna.

EI3IX Joe in IO53IU (40kms) reports receiving the beacon on all three frequencies.  He was using an Icom IC-7300 and an Antron-99 antenna. 

Both would be "over the hills" from my QTH, via diffracted ground wave.

Sporadic-E reports from Europe: SWL Hugh HC02 in IM67BB (1900kms), south Portugal, on all three frequencies, with FT8 SNR from -2dB to -20dB.  A total of 95 spots over a period of 3 hours and 22 minutes. He was using an AOR AR 8000 and a 2.4m sided square loop coupled into a tunable FET preamp.

PA3GHQ Kees in JO21LT (965kms), the Netherlands, on 32Mhz with FT8 SNR from -14dB to -19dB.  He was using an Elad FDM DUO SDR and a home made dipole.  A total of 8 spots over a period of 57 minutes.  Likely via Sporadic-E.

Both are for 13/05/2023.  No EU reports were received for 14/05/2023.

EI9KP to carry out Low-Band VHF Propagation Tests on Sat 13th & Sun 14th May 2023

Back in January, February and Arpil of 2023, Phil EI9KP carried out some propagation tests on the 34 MHz band. These tests are possible because the radio amateurs in Ireland are allowed to use a large part of the low band VHF spectrum.

Apr 2023 results HERE

On Saturday 13th & Sunday 14th May 2023, EI9KP will be carrying out more propagation tests but this time on three frequencies on 32 MHz, 34 MHz & 36 MHz. 

His supervised 1-watt beacon will operate from 08:00 UTC to 19:00 UTC on both days. The purpose of these tests is to investigate F2 layer propagation at this point in the solar cycle. There is a possibility of some Sporadic-E propagation as well.

EI9KP writes... "Six weeks on from the last test, I will be repeating my experiment over the weekend of 13/14th May 2023, from 0800UTC till 2200UTC om both days.

Propagation may be diverse and include diffracted groundwave, tropospheric scatter, ionospheric scatter, sporadic-E and F2 layer.  The Solar Flux forecast is 160 and Kp index 2.

For this test there are three time slots:

TS    Frequency  USB dial (kHz)
[00]  32013         32012.200
[01]  34013         34012.200
[02]  36013         36012.200

Each 1-minute sequence is 2*FT8, 2*CW and a short carrier.  The beacon power is 1W.  The antenna is a vertical dipole consisting of a 33MHz feeder dipole and a 36MHz coupled dipole."

Coverage Area: Considering that the tests will be done in mid-May, the main propagation mode will likely be Sporadic-E. This should allow the signals to be heard at the 1000-2000km range in Europe. e.g. Germany, Spain, N Italy, S France & the Nordic countries.

F2 propagation may be more difficult although a key target would be the SE of the USA. The lower 32 MHz frequency is likely to be more successful than say 36 MHz for F2 layer propagation.

Antenna: The antenna that Phil is using is shown on the left.

The element on the right is a half-wave dipole for 33 MHz with an adjustable capacity hat.

The element on the left is a dipole is parasitic dipole for 36 MHz which is coupled by its proximity to the main 33 MHz dipole. The purpose of this element is to extend the VSWR bandwidth of the antenna so that it can cover from 32 MHz to 36 MHz.

The antenna is mounted on a fibreglass mast.

The coax feed is probably a little bit too close and may distort the radiation pattern somewhat but Phil reports that the VSWR is acceptable at 1.6 and below.

Reports: Reports to EI9KP on QRZ or you can leave a comment here.

Results of the Low-Band VHF Propagation tests by EI9KP - 1st & 2nd April 2023

In a previous post, I outlined how Phil, EI9KP was carrying out propagation tests on 32 MHz to 36 MHz on the 1st & 2nd of April 2023.

Phil, EI9KP send on the following report... "I ran the time slot beacon test 32...36 MHz over the weekend of 1-2 April 2023, unfortunately few reports.  

F2 propagation favoured a north/south path, mainly a zone across north Africa (simulation).  SFI (Solar Flux Index) was in a trough at 125 and MUF over Ireland was very low at 25MHz, touching 28MHz by late afternoon.

I have N3IZN in California and K9MY in Illinois reporting they were listening but nothing heard. 

Michael EI3GYB reported on your blog that he could receive the beacon on all frequencies, from his QTH it would have been a diffracted ground wave.

The beacon software, hardware, dipole and band pass filter all performed without any problem.

I am planning a repeat test in about 4 to 6 weeks, hoping for higher SFE and perhaps sporadic-E."

*****

Michael, EI3GYB is located about 30kms to the south-east of EI9KP and sends on the following report... "I monitored the beacon on both days during several hours of the days at my QTH in locator io53ot.

I used two transceivers- an ICOM IC-7200 and a YAESU FT857D. Both TRX had Windom antennas for reception.

I copied the signals on all 5 frequencies with both TRX. The signals on the Yaesu were a bit weaker than on the ICOM. The signal meter showed no bar on the Yaesu- while on the ICOM I had at least one bar, sometimes two.

33,34,35 and 36 MHz all had the same signal strengths- I'll give it a 51 on the Yaesu and a 52 on the ICOM. The signal on 32 MHz was weaker- on both TRX. I'll give it a 31 on the Yaesu and a 41 on the ICOM.

There was a noticeable fading on all 5 frequencies. Slow QSB, not too deep though."

Larry, VO1FOG in Newfoundland reports listening on both days on CW and hearing nothing. Over the last few days, I have heard the WSPR signal on 28 MHz from VE1VDM in Nova Scotia many times but this was often after 19:00 UTC. Perhaps the test beacon at 32-36 MHz was turned off a little early for the path to North America?

Paul, MI3LDO in the north-west of Ireland reports that the last decent trans-Atlantic opening at 34 MHz in his location was back on the 21st of March so perhaps the test was a little too late in the season for good east-west F2 layer propagation.

Analysis... As we're now in April, F2 layer propagation in the northern hemisphere is getting noticeably worse as we head towards the Summer. While there was plenty of propagation on 28 MHz over the weekend, it did seem to struggle to get up into the low band VHF region especially on east-west paths.

It seems like the test period was a bit late for F2 propagation and too early for the summer Sporadic-E season. Hopefully that will have changed for the next test in May when there should be plenty of Sporadic-E to Europe.

It was interesting to note that EI3GYB was getting slow fading over a short 30km path.

EI9KP to carry out Low-Band VHF Propagation Tests on Sat 1st & Sun 2nd Apr 2023

Back in January and February of 2023, Phil EI9KP carried out some propagation tests on the 34 MHz band. These tests are possible because the radio amateurs in Ireland are allowed to use a large part of the low band VHF spectrum.

Jan 2023 results HERE

Feb 2023 results HERE

On Saturday 1st & Sunday 2nd April 2023, EI9KP will be carrying out more propagation tests but this time on five frequencies from 32 MHz to  36 MHz. 

His supervised 1-watt beacon will operate from 08:00 UTC to 19:00 UTC on both days. The purpose of these tests is to investigate F2 layer propagation at this point in the solar cycle. There is a possibility of some Sporadic-E propagation as well.

EI9KP writes... "The test beacon is now a time slot beacon and can run a different frequency for each time slot, from 32MHz to 36MHz. There are 5 time slots available, being minutes [00], [01], [02], [03] and [04].  Each time slot will have the sequence: 2*FT8, 2*CW followed by a short carrier.  The time slots repeat at 5, 10, 15, etc., minutes.

The time slots and frequencies are:

TS     Frequency   USB dial (kHz)
[00]  32013         32012.200
[01]  33013         33012.200
[02]  34013         34012.200
[03]  35013         35012.200
[04]  36013         36012.200

The CW and carrier should appear at 800Hz on the waterfall and the FT8 signal a little higher.  The beacon frequency is synchronised to GPS and should have an accuracy of 1Hz or better.  The antenna is a dipole in vertical polarisation, beacon power is still 1W."

Coverage Area: Considering that the tests will be done at the very start of April, there should be some F2-layer propagation still about. If my 28 MHz WSPR reception reports are anything to go by then a key target will be the eastern half of the USA.

The key difference between this test and the previous ones is of course the lower frequency of 32 MHz. Not only is that more likely to be propagated by the F2 layer in the ionosphere but it's also likely that a lot of people may be listening with antennas designed for the 28 MHz (10m) band and they might perform better at 32 MHz as opposed to 34 MHz.

As noted earlier, the Sporadic-E season in the northern hemisphere should be starting in April and there is a possibility of some Sp-E to Europe during the tests.

Antenna: The antenna that Phil is using is shown on the left.

The element on the right is a half-wave dipole for 33 MHz with an adjustable capacity hat.

The element on the left is a dipole is parasitic dipole for 36 MHz which is coupled by its proximity to the main 33 MHz dipole. The purpose of this element is to extend the VSWR bandwidth of the antenna so that it can cover from 32 MHz to 36 MHz.

The antenna is mounted on a fibreglass mast.

The coax feed is probably a little bit too close and may distort the radiation pattern somewhat but Phil reports that the VSWR is acceptable at 1.6 and below.

Reports: Reports to EI9KP on QRZ or you can leave a comment here.

Results of the 34 MHz Propagation Tests - Sat 25th & Sun 26th Feb 2023

On Saturday the 25th and Sunday the 26th of February 2023, Phil EI9KP conducted some propagation tests on the 9m band in the low-VHF part of the spectrum. He operated a supervised beacon on 34.013 MHz for most of the daylight hours running 1-watt into a vertical dipole with capacitive loading.

This was the second weekend of tests on the 34 MHz band and the results of the January 2023 tests can be seen HERE

EI9KP reports... "I have collated the below information from my 34MHz beacon test on 25/26 February 2023.  The beacon 1W transmitter and the dipole in vertical polarisation worked without technical problems.

On Saturday, I got a few reception reports from the USA.  On Sunday, propagation conditions were generally poor with maximum usable frequency (MUF) reaching only 26 MHz by late afternoon, and I received no reception reports. There was an absence of tropo over Ireland and the UK and no Sporadic-E was reported.

Also, there were no reception reports from the east, conditions were not right. It was positive that HAMs and SWLs were listening out, I have a few new names in the log."

Report: As compiled by Phil with a few additions from myself ...

Saturday 25th February 2023: SF-index: 164  A-index: 6  Kp-index: 2

Absence of tropo conditions over EI/GB/Europe.
Beacon on at 0712, beacon off at 1843.
 
13:47 UTC. Reception report from SWL W1-7897 Bill in Douglas, MA, USA. He was using a 5 element beam for the 50 MHz band and a Yaesu FT-847 transceiver.
 
17:30 UTC. SWL David in Indian River City, FL, USA. He was using an Airspy R2 with a non-resonant OmniX airband antenna on the side of Rohn tower 14 metres above ground level.
 
17:31 UTC. K5YT Ed in Texas, USA, reported that he received the FT8 at -17dB SNR but could not hear the CW part.  He was using a 2 el. tribander Hygain TH2-MK3 and an Icom IC-7300.
 

Edward Johnson, K5YT writes... "I copied EI9KP on 02/25/2023 for 4 decodes using a Hygain TH2-MK3 @ 100’ and a IC7300 de K5YT EM22"

The following were listening but nothing received:

DJ0MEW Bert in Germany - JN68IE. He was using an ICOM IC-7300 and an OCF dipole 40m long.

EI8DJ Don south of Cork city on the south coast of Ireland - IO51UT.

EI7GL - Just to add I live a few kms from EI8DJ and I also heard nothing via tropo or F2 backscatter. EI9KP is about 250kms from my location.

Franz van Velzen, OE3FVU in Austria writes... "I am monitoring here (since 7.30 UTC) with 3 receivers and antennas: IC7300 with tuned SteppIr; IC-R8600 with 3 ele 6m beam and FT-847 with Gap Titan plus Tuner. Not ideal, but perhaps I copy on one of them. All report to PSK reporter: with OE3FVU/3, OE3FVU/RX and OE3FVU respectively. At this moment (08:35 UTC) no signal has been received yet."

Kees Smit in the Netherlands writes... "I am also monitoring with 3 radio’s. Elad FDM DUO SDR with HM dipole for 40 Mhz. 8 mtr. in the attic. Yaesu FT991A with Hyendfed short version 15,6 mtr. for 10/20/40 & 80 mtr. Directional west. Kenwood TS690SAT with Wellbrook ALA1530 LNP in the garden below sea level. 2 fake decoded and nothing else at the moment but still waiting on a signal."

Sunday 26th February 2023: SF-index: 152  A-index: 10  Kp-index: 3

Absence of tropo conditions over EI/GB/Europe.
Beacon on at 0730, beacon off at 1814. No reception reports.
All morning a 'wedge' in the MUF over Ireland, England to France.  Low MUF at 18-21MHz. 

The following were listening but nothing received: 

DB6LL Ham in JO43VP (near Hamburg), he was using a Yaesu FTDX101MP and a non-resonant 5/8 lambda vertical antenna for 10 metres. Decoding was on JTDX.

K5YT Ed in TX, USA.

Analysis: In contrast to the January tests, conditions for the February 2023 tests were very much subdued. The was a large aurora later on the evening of the 26th of February which shows how disturbed conditions were. 

Most of the stations listening in Europe were well inside the F2-layer skip zone and it's possible that a repeat of the test during the summer Sporadic-E season would yield much better results. 

The path to the stations in the USA was likely due to two or more hops off the F2 layer in the ionosphere.

EI9KP to carry out 34 MHz Propagation Tests on Sat 25th & Sun 26th Feb 2023

On the 21st & 22nd of January 2023, Phil EI9KP carried out some propagation tests on the 34 MHz band - Results HERE

Now one month later, EI9KP will be carrying out test transmissions on the 34 MHz band (9m) band on Saturday the 25th & Sunday the 26th of February 2023. The beacon will operate from sunrise (07:34 UTC) to sunset (18:04 UTC) on both days. The purpose of these tests is to investigate F2 layer propagation.

EI9KP will be transmitting on 34.013 MHz. The sequence of the beacon will be 2 x FT8, 2 x CW ID & Locator, short carrier.  The 2 x CW part is to help SWL's who do not use digital modes and also help during QSB cycles.

The beacon will be GPS disciplined with an output power of 1-watt. The antenna last time was a horizontal dipole with capacity hat loading. This time, he will be using vertical polarisation with the antenna on an insulated mast and should have a clean omni-directional pattern. 

To listen for this beacon, try 34.013 MHz CW or 34.0122 MHz USB.

Predicted Coverage Areas...

The map above shows the predicted coverage area at 12:00 UTC for a 1-watt FT8 transmitter operating at 30 MHz. It's not quite 34 MHz but it's close.

It clearly shows the first F2 hop going from Ukraine, Romania, Bulgaria, Greece... to the far south of Italy and perhaps the far south of Spain and Portugal. The path to the Canary Islands looks particularly good.

It's possible the second F2 payer hop might reach parts of the Caribbean and the SE of the USA.

The image above shows the likely coverage area at 17:00 UTC. It seems good in the SE of the USA and during the January tests, the signal was heard in Florida and Texas. 

Reports to EI9KP on QRZ or you can leave a comment here.

Note that it may be possible for stations in western Europe to hear the signal via backscatter. Leave your radio on 34.0122 MHz USB and see if you can get a decode of the FT8 signal.

Results of the 34 MHz Propagation Tests - Sat 21st & Sun 22nd Jan 2023

On Saturday the 21st and Sunday the 22nd of January 2023, Phil EI9KP conducted some propagation tests on the 9m band in the low-VHF part of the spectrum. He operated a supervised beacon on 34.013 MHz for most of the daylight hours running 1-watt into a horizontal dipole with capacitive loading.

This is a report on who heard his signal over the two days.

Phil, EI9KP writes... "This 34MHz beacon experiment got people interested in listening and I am pleased to have received the reception reports below.  Also I'd like to express my thanks to Paul Logan in Co Fermanagh for twittering his followers.

Two reception reports from EI, two from Europe and to my delight a few from the USA. 

YO9FTR in Romania at 2795km received the signals on both days.  He suggested that start earlier on Day 2, in fact propagation was waiting when I switched on and he decoded the first 15 seconds of the beacon's FT8 sequence.

N2OTO in Florida is near enough twice the distance than VO1FOG in Newfoundland, on the same great circle line.

 K5YT at 6864km / 4265 miles was the greatest distance. Edward, K5YT in Texas was using a Hygain TH2-MK3 tribander @ 30m (100’) as a receive antenna.

FT8 signal received by K5YT in Texas

The USA reports suggest F2 propagation, but how many hops to FL or TX?  What about the one from CT?

YO9FTR made a long observation of the signal/SNR. This wasn't pre-arranged, however, I am thankful for the data and realised there was some pattern in it.  The resulting graph shows signal/SNR over several hours, really a nice observation of propagation.

So, I enjoyed the experiment, there's always something new to learn.

 73, Phil EI9KP"

If I missed any reports then let me know.

Analysis... It should be noted that the reports above are from a beacon running just 1-watt which is pretty amazing. It just goes to show how far a signal can travel via F2 layer propagation with relatively low attenuation.

Let's have a look at a propagation map.

The map above shows the predicted coverage for a 1-watt operating at 30 MHz. It's not quite 34 MHz but it's close. The solar flux was just around 200-210 for the test.

YO9FTR... For most of the daylight hours, Romania is in the ideal spot for F2 layer propagation and reception of the beacon. The reception chart from YO9FTR further up this post shows reception of the 34 MHz signal from 08:43 to 11:41 UTC.

In the 'old days' when listening just by ear, it would have appeared that the signal was in and out, missing for long periods and then strong for a while. With a weak signal mode like FT8, we can see that the signal was actually there all of the time for three hours. The software was able to decode the FT8  signal when it was buried in the noise.

HB9TMC... It's hard to know for sure what propagation mode was responsible for the reception of the beacon signal in Switzerland. It's seems a bit too close for F2 layer. Was it Sporadic-E? Backscatter? Paul, MI3LDO heard French roads control traffic on 35/36 MHz on Saturday afternoon and thinks it was almost certainly Sporadic-E.

USA... Florida seems to be in the perfect spot for reception. It's the most southerly path and it's in the right area for the second F2 hop. Texas would seem to be at the edge of the footprint.

Overall an interesting test and a very successful one considering the relatively small number of people that would have known about the transmissions. It's also worth noting that very few people have antennas for 34 MHz and most are listening on antennas tuned for other bands.

Ireland is the only country in the world as far as I know where radio amateurs can transmit at 34 MHz (9m band). It lies pretty much half way between the 10m band (28 MHz) and the experimental 8m band at 40 MHz.

For more information about other 34 MHz tests, I'll keep the posts on my 40 MHz page HERE

EI9KP to carry out 34 MHz Propagation Tests on Sat 21st & Sun 22nd Jan 2023

Phil, EI9KP has announced that he will be carrying out test transmissions on the 34 MHz band (9m) band on Saturday the 21st & Sunday the 22nd of January 2023. The beacon will operate from 11:00 until 17:15 UTC on both days. The purpose of these tests is to investigate F2 layer propagation.

EI9KP will be transmitting on 34.013 MHz. The sequence of the beacon will be 2 x FT8, 2 x CW ID & Locator, short carrier.  The 2 x CW part is to help SWL's who do not use digital modes and also help during QSB cycles.

The beacon will be GPS disciplined with an output power of 1-watt. The antenna is a horizontal dipole with capacity hat loading.

To listen for this beacon, try 34.013 MHz CW or 34.0122 MHz USB.

Predicted Coverage Areas...

The map above shows the predicted coverage area for a 1-watt FT8 transmitter operating at 30 MHz. It's not quite 34 MHz but it's close.

It clearly shows the first F2 hop going from Ukraine, Romania, Bulgaria, Greece... to the far south of Italy and perhaps the far south of Spain and Portugal. The path to the Canary Islands looks particularly good.

To the west, the first F2 hop includes Newfoundland and the recent tests confirm this. Phil writes... "Larry VO1FOG reports receiving the beacon at 12:42UTC (his email time stamp) and all the way through till sunset, which for my QTH was 16:48UTC.  F2 layer propagation.  He reports that the signal was particularly strong about half an hour before sunset, to disappear all together at sunset. He reported a similar signal peak yesterday, just before sunset."

It's possible the second F2 payer hop might reach parts of the Caribbean and the SE of the USA.

Sunset for his Phil's location is at 16:54UTC on Sat 21/01 and 16:56UTC on Sun 22/01.

Reports to EI9KP on QRZ or you can leave a comment here.

Note that it may be possible for stations in western Europe to hear the signal via backscatter. Leave your radio on 34.0122 MHz USB and see if you can get a decode of the FT8 signal.

Trans-Atlantic opening at 34 MHz - 16th Jan 2023

Radio amateurs in Ireland have permission to use large portions of the low-VHF spectrum for experiments and Phil, EI9KP has been carrying out tests at 34 MHz which is the 9-metre band.

Phil conducted some tests during the Quadrantids meteor shower at the start of January 2023 and the results can be seen HERE.

With the rise in solar flux to over 230 and the rise in the maximum usable frequency (MUF) into the low-VHF spectrum, Phil conducted some tests on the 16th of January 2023 and his 1-watt beacon was heard across the North Atlantic in Newfoundland!

EI9KP writes... " I am delighted that the 1W beacon was received at 13:27UTC by VO1FOG in Newfoundland, Canada, a distance of 3145km/1995mi.  A first report from across the Atlantic, likely F2 propagation.  Thank you Larry for the report and sound clip.

Given high SFI next few days and possibility of F2 type propagation I will turn on the beacon again tomorrow Tuesday 17/01/2023 from 11:00 till 17:00 UTC. "

EI9KP's 1-watt beacon on 34.013 MHz is based on a RF Zero board with GPS stabilisation. The beacon is self contained in a die cast aluminium box with a 2x16 char. LCD display and a few status LEDs. The sequence was 3 x FT8 transmissions, then a CW ID and then a carrier.

The beacon antenna is also an experiment in that it is a shortened (capacitive hat) dipole with sliding end tubes that can adjust for frequencies from 32MHz to 60MHz.

More info in this previous post.

Update 17th Jan: VO1FOG also heard the test signal from EI9KP on the 17th of January 2023. The audio recording below shows the CW and FT8 signal.

It's likely that the close in reports (<1000kms) were probably due to meteor scatter and not Sporadic-E although at the peak of the shower, it might not be possible to tell the two propagation modes apart.

I managed to get one successful FT8 decode but it was only one over the space of 12-hours. If the propagation mode was tropo or aircraft scatter then I'd expect a lot more decodes. I think I probably caught a large meteor burst at 01:02 UTC.

There were no F2 propagation reports but the 34 MHz signal will almost certainly cross the Atlantic when the conditions are good. 

EI9KP's 1-watt beacon on 34.013 MHz is based on a RF Zero board with GPS stabilisation. The beacon is self contained in a die cast aluminium box with a 2x16 char. LCD display and a few status LEDs. The sequence was 3 x FT8 transmissions, then a CW ID and then a carrier.

The beacon antenna is also an experiment in that it is a shortened (capacitive hat) dipole with sliding end tubes that can adjust for frequencies from 32MHz to 60MHz.

Other Tests... Phil reports... "I have been testing on 34MHz on and off during 2022. On 12/06/2022, I  had a 2-way QSO (FT8) with EI4GNB Tim in IO63 and on 2-4/12/2022, I was testing 34MHz propagation with LY2YR, but no reception his side.

On New Year's Day listener Paul Logan in Lisnaskey, Co. Fermanagh received the beacon signal at 12:03 and with a Delta Airlines jet passing over the signal, the beacon signal jumped suddenly from 0dB to +11dB for one over.  He heard it fluttering up.  So a groundwave (note: Cuilcagh sits prominently in the path) plus aircraft scatter?

Upcoming propagation tests at 34 MHz - 4th Jan 2023

Phil, EI9KP in the west of Ireland will be conducting some propagation tests on the 34 MHz (9m) band on Wednesday the 4th of January 2022. This coincides with the peak of the Quadrantids meteor shower which is expected to peak around 03:00 to 04:00 UTC on the 4th.

EI9KP will be using a supervised 1-watt beacon on 34.013 MHz into a horizontal dipole with capacitive end loading. The beacon sequence is three x FT8 (15s) transmissions, then a CW ID (callsign + locator) and then a 4-second carrier which completes the 1 minute period. The cycle then repeats.

Before anyone asks, yes... it's 34 MHz and not a mistake. Radio amateurs in Ireland were given permission to carry out experiments in most of the low-VHF spectrum back in April of 2018. See previous post HERE

Times & Frequencies... a) The beacon for the propagation tests will run from 00:01 UTC  to 17:00 UTC on the 4th of January 2023.

b) The frequency in use will be 34.013 MHz. Set your radio to 34.0122 MHz USB and the tone of the CW signal should be 800 Hz. The FT8 signals will probably be a bit higher.

If you're within say 1000kms of EI9KP then leave your radio on FT8 overnight and see if you get any decodes. I know MSK144 would be a better mode for meteor scatter but it's not part of the software that Phil is using. This is also a basic experiment, a lot more people are geared up and familiar with FT8 than MSK144.

Any listeners close in... say under 200kms may hear the signal by ground wave, tropo or via aircraft scatter. 200-1000kms should be ok for meteor scatter.

From 09:00 to 17:00, F2 propagation should come into play and there is a possibility the signal may be heard in Europe or North America. And of course, you can never rule out the possibility of Sporadic-E popping up.

If you're interested then have a listen and be sure to send your reports to Phil, EI9KP on QRZ. You can leave them as a comment here if you wish.
