Selective TEP opening on 144 MHz from the Caribbean to South America - 9th Feb 2022

9th February 2022: There was another TEP (Trans-Equatorial Propagation) opening on 144 MHz between the Caribbean and South America but this time, it was a bit unusual.

As the map above shows, nearly all of the signals shown on the PSK Reporter website were from Argentina to Aruba, Bonaire, Curacao and the Dominican Republic. There was also some from Argentina to Puerto Rico. What was unusual was the lack of signals further east from Puerto Rico to the south of Brazil.

Usually there are two parallel TEP paths crossing the Geomagnetic Equator. For whatever reason, the eastern path to Brazil seems to have been mostly absent.

Spots on the DX Cluster show a small bit of activity from Puerto Rico to Brazil but it seems to have been at a very low level compared to the path further west.

The path from PY5EK in Brazil to WP3DN in Puerto Rico was the only one I noticed on the PSK Reporter website.

As for why the western TEP path was better than the eastern TEP path???

Most of these contacts were in the region of 5,000 kms.

For the TEP contacts with Argentina, PJ4MM was using 100-watts to a 13-element Tonna Yagi which is 13 metres above ground level.

PJ2BR completes 5461km contact on 144 MHz with just 10-watts - 7th Feb 2022

At the moment, there seems to be an TEP opening on the 144 MHz band every evening between South America and the Caribbean area. The evening of the 6th of February was no exception with an opening just after midnight UTC on the 7th (~8pm for the stations involved on the evening of the 6th).

Brett, PJ2BR in Curacao reports working stations in Argentina with just 10-watts into a 3-element Yagi!

PJ2BR writes... "This is an unusual evening. Was able to work @LU4DJC, @LU1FAM and @LU2EPO on 2m Q65. What makes this unusual is, made the contact with 10W and a 3 element Arrow yagi! My signal was also rx’ed in Uruguay. 5461 Km on 2m 10W!"

Many people will be familiar with the Arrow dual band antenna which is often used to work the satellites.

5,461 kms on 144 MHz with just 10-watts in to a 3 element Yagi is pretty amazing. Remember that this is via Trans-Equatorial Propagation and not via some satellite passing over. 

It is also a LOT further than the 3000kms or so across the North Atlantic from Newfoundland to Ireland which has never been bridged on 144 MHz.

To complete the contact, PJ2BR was using the Q65 digital mode...

In this screen shot, LU2EPO in Argentina was hearing PJ2BR at -16dB which is just below what is detectable by ear.

There are the spots from the DX-Cluster for the opening...

FM radio stations from Jamaica heard on 89 MHz & 96 MHz in Chile via TEP

Pipe, CE3SX / CE3SAD in Chile writes to say that he managed to hear two FM radio stations on 89.9 MHz and 96.1 MHz from Jamaica during a TEP opening recently.

CE3SX writes... "Stylz FM 96.1 from Port Antonio and KLAS 89.9 from Kingston, Jamaica heard in Chicureo, Santiago, Chile FF46pr Via Trans-Equatorial Propagation

Date: January 31 and February 01, 2022. Hours: 21.46CEv 00.46 UTC and 22.03CEv 01.03 UTC

Maximum distance: 5,755 km"

As Pipe outlines, the distance is around 5,700kms and is approaching the maximum distance usually associated with Trans-Equatorial Propagation. 

A video clip of the reception is shown below...

Pipe also notes that regular reception TEP signals on the 88-108 MHz band from Columbia and he is using a 7-element Band 2 Yagi as designed by YU7EF.

CE3SX also notes that there are no 144 MHz stations in Columbia (HK) and Jamaica (6Y) to try on the 2m band.

As I outlined in a recent post, there are parallel paths from Brazil and Argentina to the Caribbean on 144 MHz during TEP openings and it's likely that similar paths are there further east from Chile to Columbia, Jamaica and Cuba on 2m.

Good opening on 28 MHz to North America - Sat 5th Feb 2022

Saturday 5th February 2022: Over the last few weeks, there have been some good F2 openings on 28 MHz to the east but it has been poor to the west. On the 5th of February, things flipped around a bit with poor F2 conditions to the east but very good to the west.

The map above shows the WSPR signals that I heard on 28 MHz and as you can see, there are plenty of signals from North America. The two that were of special interest were the northerly path to Utah and Arizona.

It was also nice to see that some of the stations were running just 200-milliwatts. 

There was also some Sporadic-E to Europe.

The solar flux on the day was 130.

Stations running 200mW or less...

5000km mobile contact on 144 MHz SSB between Puerto Rico & Paraguay - 4th Feb 2022

This report is really pretty amazing. Jose, WP4KJJ reports that he managed to complete a SSB contact on 144.300 MHz with Juan, ZP9HTL in Paraguay while operating mobile!

Jose said that he was using an ICOM IC-7000 radio with a COMET vertical antenna on his vehicle.

He said that ZP9HTL was 5/1 on SSB.

This contact was via Trans-Equatorial Propagation (TEP) and the distance was 5,018 kms!

It's one thing to make contacts with Yagi antennas on a mast but to complete a 5,000km+ contact from a vertical antenna on a pick up truck on 144 MHz is pretty amazing. 

Remember that the distance across the North Atlantic between Ireland and Newfoundland is 3000kms. This was 2,000kms further.

There are people operating mobile on the HF bands who would be happy with a 5000km contact but this was on 2-metres!

TEP opening on 144 MHz... It was of course part of a bigger opening as can be seen from the map below.

Most of the activity seems to have been on the Q65 mode.

DX spots from the opening are shown below...

WSPR activity on the 40 MHz band in North America - January 2022

In 2021, seven US stations and one Canadian station were given experimental licenses for the 40 MHz band. Several are now active and using the WSPR beacon mode on the band.

This post covers the reception reports for each station in North America for January 2022.

Canadian experimental station CBG209: To allow the callsign to be recognised by WSPR, the callsign was reversed and 902BGC was used.

The openings for the month of January are shown above and I have listed the openings below with the reports under 200kms filtered out. I also removed multiple reports for the same station for the same opening. The power is listed as 10 watts.

Even though it's mid-Winter, there seemed to have been five distinct openings. Most of the signals can be accounted for by mid-Winter Sporadic-E or possibly Auroral-E propagation but the one that really sticks out is the 3365km opening to W3PM in Alabama. 

The maximum distance for one hop Sporadic-E is about 2200kms. As it occurred near the end of an opening, it was probably due to double hop / chordal hop Sporadic-E.

WM2XCW in Washington State: Just local reports for this station during the month.

There seems to have been seven openings during January. Most of them are Sporadic-E but it's interesting to see several in that 300-800km region which is usually inside the Sp-E skip zone.

In conclusion: To the best of my knowledge, there is no WSPR activity in Europe at present and the guys in North America are certainly leading the way. 

Despite the fact it was January and mid-Winter, there is plenty of evidence of openings on the 40 MHz band. Once we get to May, these openings in the region of 800-2000 kms should start to become a lot more common. 

Looking through the full reports for January, most of the signals were buried in the noise and it shows the advantage of using a weak signal mode like WSPR as opposed to just plain CW. If all of these experimental stations had just CW beacons then I certainly wouldn't be writing this post as little or nothing would have been reported.

Some thoughts...

1) It would be nice if more people set up receivers for the band and listened for WSPR signals.

2) We'll have to wait and see if the remaining three experimental US calls have any interest in getting up and running on WSPR.

3) It would be great to see some WSPR activity in Europe as well. Anyone interested??

Another TEP opening on 144 MHz between S America & the Caribbean - 2nd Feb 2022

Wednesday 2nd February 2022: Another day, another big Trans-Equatorial Propagation (TEP) opening on 144 MHz between South America and the Caribbean. The map above shows the parallel paths from Argentina to Bonaire, Curacao & the Dominican Republic and from Brazil to Puerto Rico, Martinique, Guadeloupe and Trinidad.

The parallel paths are due to the fact that at 144 MHz, TEP signals must cross the Geomagnetic Equator close to right angles. At lower frequencies like 50 MHz and 28 MHz, the angle can be much wider.

I have included a list of the spots from the DX Cluster at the bottom of the post.

Video: Brett, PJ2BR in Curacao has a nice video clip of a LW2DAF on 144.300 MHz SSB.

Caribbean: This is a map in closer detail of the stations in the Caribbean...

The reason I include this is that it shows the usual stations and countries in the Caribbean that are taking part in these TEP openings on 144 MHz. The map also shows all of the other countries where there doesn't seem to be much if any 2m activity.

The map just got me thinking... could more people in the Caribbean get active on 2m?

Chile? Cuba? Columbia? Central America?... In other previous posts, I've looked at TEP openings on the 88-108 MHz band between Chile and Columbia. 

Q. Do these reach 144 MHz as well? Is the lack of contacts just because there are no stations from some of these countries on 144 MHz?

CO8LY was mentioned on the DX cluster but I couldn't see any record of a path on the PSK Reporter website.

432 MHz??? Lots of questions today! 

Q. If there is a really good TEP opening on 144 MHz in South America, can it reach 432 MHz? It's been done before between Zimbabwe and Greece.

Q. Is anyone trying to make a 70cms contact via TEP at the moment? 

Q. Is it only possible at the peak of the solar cycle?

Antarctica heard on 28 MHz - 1st Feb 2022

Tuesday 1st February 2022: While conditions on 28 MHz weren't as good as the 31st of January, the 10m band still opened to Australia. I was listening on WSPR all day and the most interesting signal for me however was the German Antarctic research station DP0GVN.

These are the WSPR decodes from Australia & Antarctica...

If you examine the signal strengths then you'll notice that they are all down down in the -20dB to -29dB region i.e. they're buried in the noise and well below what I could hear by ear.

Even if the signal is really weak, there is still a bit a of 'wow' moment when Antarctica appears on the screen on 10m.

Big TEP opening on 144 MHz between South America & the Caribbean - 1st Feb 2022

Tuesday 1st February 2022: The impressive looking map above is from the PSK Reporter website and it shows some of the paths that were open on 144 MHz on the the 1st of February between South America and the Caribbean.

And yes, that's 144 MHz! ...the VHF band that is supposed to be 'line of sight' as we're often told.

Most of the contacts were between 3,700 and 6,000 kms.

The opening which was around 01:00 UTC or 20:00 local time was due of course to TEP - Trans-Equatorial Propagation. Most of the paths on 144 MHz were at right angles relative to the Geomagnetic Equator.

Most of the contacts seem to with the Q65 mode with a few on FT & SSB.

Here are the 144 MHz spots on the DX-Cluster from Brazil & Argentina...

Good opening from Europe to Australia on 28 MHz - 31st Jan 2022

Monday 31st January 2022: There was a nice opening on 28 MHz on the 31st with some strong signals between Australia and Europe.

The map above shows what I heard on WSPR on 28 MHz on the 31st. While conditions were poor to the west, it was good to the south and the east. It's worth noting that this is WSPR where there is a limited number of stations transmitting. If I had been listening on FT8 then the map would have a lot more dots.

I heard four VK stations on WSPR with all three of the VK3 stations near the city of Melbourne. 

The 50 watt signal of VK3KCX/1 had a signal to noise ratio of +8dB which is up at the level where a SSB contact would be possible. It was nice to see the 2 watt signal from VK3QD also making it through with a signal of -23dB.

I also heard the VK8VF beacon near Darwin on 28.268 MHz which was just above the noise. There's something magic about actually hear a CW signal from the other side of the world on 28 MHz. 

The video clip below from G8DX shows how strong the signals were on SSB...

Amazing conditions on 28MHz today - here’s a short clip of VK3KJ from this morning with my aerial at just 25ft due to strong winds #hamradio pic.twitter.com/RFsS2acrnN

The solar flux was up at 130 so it seems the sun is well up on the 100 or so of late.

New 40 MHz beacon WM2XCS now operational from New Jersey

George, N2CG has one of the seven experimental 40 MHz permits in the USA and was given the callsign WM2XCS. He has just announced that he now has an operational 40 MHz beacon from his location in New Jersey.

George writes..." I am happy to announce that on January 26, 2022 at 1900 UTC WM2XCS beacon began operating on 40.685 MHz CW mode at 10 Watts output into a SIRIO 8m 5/8 wave vertical
antenna.  

The WM2XCS CW beacon on 40.685 MHz sends the following message at 12 WPM: "VVV DE WM2XCS BCN WM2XCS BCN FN20WV NNJ 5 seconds dash AR" that takes about 50 seconds to send.  This message is followed by a 60 seconds delay and then the sequence repeats.  My transmitter frequency tolerance is +/- 0.5 ppm.

For now, I operate the beacon about 10-11 hours a day beginning around 8 AM EST (1300 UTC) to 7 PM EST (0000 UTC).  Signal reports and/or spotting reception reports of my 8m beacon will be most welcomed.

I encourage all when hearing my beacon to spot your report on the DXMAPS website ( www.dxmaps.com ) that indicates 40 MHz band reports.

73, George  WM2XCS/N2CG"

Analysis... This beacon should be widely heard once the Sporadic-E season begins in the second half of April. The map above shows the typical range for Sporadic-E signals on the 40 MHz band while most of the openings should be around the 1200-1800km mark.

This in effect means that stations in Wisconsin, Illinois, Tennessee, Georgia and the north of Florida are the most likely to hear it during the Summer months.

There will be openings in the range of 2000-2300kms but these will be weaker.

During the months of May, June & July, there should be more multi-hop Sporadic-E openings. This should allow openings from New Jersey to California and from New Jersey to Europe.

The fact the beacon is CW only and doesn't have a digital component like FT8, PI4 or WSPR means the conditions will really need to be good.

What will be really interesting to see if the rising solar flux levels result in an opening via the F2 layer? Will the MUF reach the 40 MHz band?

Certainly, F2 layer propagation from New Jersey to California and Europe on 40 MHz at the peak of the upcoming sunspot cycle will be possible.

It would also be very interesting to see if anyone in South America is able to hear this beacon.

Listening for the WM2XCS beacon... For the 40 MHz band to open, the 28 MHz band below it will almost certainly be open as well.

I have compiled a short list of 28 MHz beacons which are in the general area of WM2XCS...

K3CX/B 28.2025 FN20CI 
WN2A/AK2F 28.2085 FN20OU 
K3FX/B 28.2160 FN20XE
N3TVV/B 28.2320 FN20DU
N2MH/B 28.2325 FN20UT

KA3JOE/B 28.2495 FN20MD
KB2RSK/B 28.2685 FN22QW
WA3NFV/B 28.2700 FN20IH

If you can hear any of those beacons on 28 MHz then that would be a good time to look for the WM2XCS beacon on 40.685 MHz.

3155 km opening on 144 MHz between Australia & New Zealand - 28th Jan 2022

28th January 2021: There was another 3000km+ opening on 144 MHz between Australia and New Zealand when Peter, VK5PJ in Adelaide received the WSPR signal from Bob, ZL1SIX.

The two WSPR decodes are shown below and the signals were pretty weak at -19 and -20dB.

 UTC (y-m-d) TX txGrid RX rxGrid MHz W SNR drift km
2022-01-28 01:06 ZL1SIX RF64vt VK5PJ PF95mk 144.490537 10 -21 0 3155
2022-01-28 01:12 ZL1SIX RF64vt VK5PJ PF95mk 144.490537 10 -19 0 3155

The map above shows the WSPR signals heard on 144 MHz by VK5PJ over a 24 hour period. Most of the Australian signals are tropo but the 3155km distance was really something else.

Remember, 3155kms is the distance between Ireland and Newfoundland across the North Atlantic.

Propagation??... It's important to note that VK5PJ was the only station in Australia to hear ZL1SIX on 144 MHz that that. i.e. none of the closer stations near the south-east coast heard him. This does suggest that Sporadic-E was the main propagation mechanism.

One single Sporadic-E hop might account for a maximum of say 2300kms but not 3155kms. What makes up the difference?

The map above shows the tropo prediction from Pascal, F5LEN and it suggests that there might have been some tropo ducting over the Tasman Sea.

It's possible that the western path of the 3155km path was due to Sporadic-E and that coupled into a maritime duct for the remainder of the circuit to New Zealand.

A second option was that it was due to chordal hop Sporadic-E with the signal going between two Sporadic-E 'clouds'. This does happen at 144 MHz but it is relatively rare.

It's impossible to know for sure what the propagation mechanism was but the probability of a combined Sp-E / tropo duct opening is higher.

A snapshot of conditions on 28 MHz - 28th Jan 2022

Friday 28th January 2022: As an experiment, I left my radio on 28.074 MHz to monitor the FT8 activity and to see what the current conditions on 10-metres are really like. The results are shown above and they show I heard 181 stations in 35 DXCC countries.

Every day, I listen for WSPR signals on 28 MHz and I know that I'm not seeing the full picture due to a lack of stations. FT8 is quite simply the best way at present to see what the conditions on a band are like.

In terms of DX, it's always nice to hear Australia on 28 MHz and I logged a total of 15 on FT8.

Radio astronomers image sky at 144 MHz in more detail

I came across an interesting article today about how radio astronomers are in the process of plotting the radio sources of the northern sky in more detail at 144 MHz.

The problem up to now is that the ionosphere slightly distorts the signal at 144 MHz and that impacts the resolution of the radio image. A team of radio astronomers have now worked out a way to compensate for this distortion which allows resolution of radio sources at much greater detail. Some of these are shown above.

The paper was published in Nature Astronomy on the 27th of January 2022 and a preview can be seen HERE

Tracking a German Polar Research Ship on 28 MHz - Dec 2021 & Jan 2022

For the last few weeks, I have left my HF radio on the 10m WSPR frequency of 28.1246 MHz and any signals I decode are uploaded automatically to the WSPRnet website.

One of the more unusual signals that I have heard over the last few weeks was DP0POL, the WSPR station on the German polar research vessel Polarstern.

I first noticed this when it was off the west coast of Africa. Between the 22nd of December 2021 and the 3rd of January 2022, I heard the 5-watt signal a total of 39 times. The distances range from 5116 kms to 9705 kms.

I remember checking this a few weeks back and there were no earlier reception before it was off the west coast of Africa. Possibly, it was inside the F2 layer skip zone for me when it was further north.

Back in May of 2021, I was able to track the same ship on 28 MHz as it made its way through the North Sea.

Interview with W1ZY about Phased Vertical antennas for the HF bands

The Ham Radio Live YouTube channel recently had a very interesting interview with William Des Jardines, W1ZY about a Phased Array Vertical Antenna as well as a simple Beverage Antenna. A video of the talk is embedded further down.

I think anyone who is interested in making and experimenting with antennas will find this of interest.

The presentation is a bit light on graphics so let's address that first.

The image above shows the general principle of a phased vertical array. By using phasing lines, signals from each vertical can either be added together and subtracted from each other.

The image above shows the view from above of the radiation pattern. Signals coming from the right are added and there is a small gain of about 3dB. The signals from the left are out of phase and there is a large drop in this direction.

With a relay and suitable phasing lines, the direction of the array can be flipped to the right or left at the flick of a switch. This has obvious advantages for say propagation and antenna tests as opposed to waiting for a Yagi to turn on a mast.

The talk also covers Beverage antennas which are used for receive only, especially on the lower HF bands.

The video is shown below and the part of interest starts at 11:30...

There are a two links for more information.

W1ZY has an article on his substack site HERE

W1ZY's QRZ page also has a LOT of information, see HERE
