New FT4 protocol hits the airwaves

Back on the 23rd of April 2019, I had a post up about the new FT4 protocol from Joe Taylor & the WSJT team.. https://ei7gl.blogspot.com/2019/04/new-ft4-protocol-announced-for-digital.html

A new Beta version of the WSJT-X software was released on Monday the 29th of April and there seems to be a lot of interest in it already.

I took three snapshots of the activity levels on the 20m, 30m, 40m and 80m bands on the evening of the 30th of April and the morning and afternoon of the 1st of May. The results are shown in chart below...

As can be seen, there are already a substantial number of people using FT8 after just 48 hours. The main band is 20m followed by 40m.

The general release for FT4 will be in July of 2019.

Although it was designed for digital contesting, it will almost certainly be used outside of contests when it is finally released. As the FT4 transmissions are 6 seconds in length as compared to 15 seconds for FT8, it is likely to be used on busy bands where the FT8 frequency is crowded and the signals are strong...i.e. 20m & 40m.

Will FT4 replace FT8 in time? FT8 does have the advantage of being more sensitive but it's hard to imagine it not being used on say 50 MHz where FT4 is two and half times faster and people are trying to work as many stations are possible during the short openings.

The website for the software is http://physics.princeton.edu/pulsar/k1jt/wsjtx.html

FT4 intro...

Late opening to EA8 on 28 MHz - Tues 30th Apr 2019

In contrast to the last few days, Tuesday the 30th of April was really quiet on 28 MHz for the most part. In fact, it had seemed pretty remarkable earlier in the day that so few FT8 signals had been heard.

By the late evening, I had pretty much given up hope of hearing anything and I wrote up a blog post with a map to say just how quiet it had been. Needless to say after getting the post ready, the band opened to the Canary Islands!

This is the updated map...

These are the stations uploaded to PSKReporter...
IK2IQC 10m FT8 1467 km 20:44:00
EA8DFQ 10m FT8 2705 km 20:34:29

G0OYQ 10m FT8 579 km 12:04:00
DO1JTS 10m FT8 1080 km 09:35:33

The opening to the Canary Islands lasted from 20:04 to 20:36 UTC. I actually heard six EA8 stations but only one was uploaded to the PSKReporter website.

201015   9 -0.2 1274 ~  CQ AM870PT
201930  -4  0.2 1276 ~  CQ EA8DFQ IL28
201945   9  0.0 1019 ~  <...> EA8SG
202015  -3  0.0 2520 ~  <...> EA8SR IL18
202015 -22  0.2 2461 ~  <...> EA8TH IL18
203515 -14  0.0 1013 ~  EA8DER R-07

As for the mode of propagation? Multi hop Sp-E? F2? The path from Ireland to the Canary Islands was close to sunset so I wonder if that was a factor?

Examples of signals heard at 34 to 36 MHz

Thanks to Rob PE9PE for sending on the link to this video which shows what a short wave listener in Italy heard from 34 MHz to 36 MHz.



This part of the low VHF spectrum is used by many government agencies and utilities. Examples given in the comments on the video were DDE = France Highway Service and Turkish Jandarma (Military Police and Country Police).

Sporadic-E on 28 MHz - Mon 29th Apr 2019

There was a pretty modest opening on 28 MHz on Monday the 29th of April as can be seen from the map below. The main opening was from 10:30 to 14:00 UTC.

The strongest signals were from North Italy and South Germany and as can be seen from the map, there was a concentration of lines in that direction.

I did notice later that GI4SNA in Northern Ireland and GM4WJA in Scotland managed to hear South America but there was nothing heard here.

These were the beacons heard...

Example of Band 1 TV Tropo Signals at 66 MHz...

Someone left a comment on the blog about the early days of TV back in the 1960's and trying to receive signals from Wales in Ireland. Rather than just leave it as a comment, I turned it into a blog post as it shows the possibility of tropo propagation on the low VHF band around 60 MHz.

Band 1 TV
The first TV broadcasts in the UK used the 405 line system on Band 1 - 45 to 66 MHz. The last of these transmitters were turned off in January of 1985 in the UK.

This is an excerpt from Wikipedia about the 405-line service in Ireland to give the post some context...

Ireland
Ireland's use of the 405-line system began in 1961, with the launch of Telefís Éireann, but only extended to two main transmitters and their five relays, serving the east and north of the country. This was because many people in these areas already had 405-line sets for receiving UK broadcasts from Wales or Northern Ireland. Telefís Éireann's primary standard was 625-line; it began using this in the summer of 1962, more than two years before the UK had any 625-line channels.

The last 405-line relays, in County Donegal, were turned off in 1982; the main transmitters had been shut down in 1978 to free up frequencies for RTÉ 2.

https://en.wikipedia.org/wiki/405-line_television_system

Thanks to Desmond Walsh for providing some details about his experience of receiving TV transmissions at 66 MHz from a transmitter in Wales, a distance of roughly 300 kms.

"When I was much younger I lived in southeast Co Tipperary and was eager to get BBC TV from Wales ( before TE came on the air)

There were two possible channels , 4 and 5 (in the old 405 line +modulation with AM sound 3.5 MHz lower , from memory ) Channel 5 from Wenvoe (100KW) had a much higher erp than Haverfordwest Channel 4 (0.044KW).

So I obtained a 4 element yagi for ch5 (63 to 68 MHz ?) and braved going on the roof of the 2 storey house to erect it on the chimney. Definitely would not do it now !

Reception of course varied with different signal strengths but gave about 50% reception , up to a week at a time of tropospheric signals when high pressure was around.

An annoying QRM happened at times when the French 819 line system blotted out Wenvoe but that is tropospheric reception for you!.

Channel 8 HTV (St Hilary 100KW CH7?? Band 3) came later but suffered from overlap with RTE Ch F , Mt Leinster.

These cross-channel signals were stronger in the Waterford city area , 15 miles downstream of the River Suir.

Desmond Walsh"

Sporadic-E on 28 MHz - Sun 28th Apr 2019

Like previous day, there was plenty of Sporadic-E about on 28 MHz on Sunday the 28th of April 2019. The band opened at about 07:30 UTC which seems a bit earlier than usual. The band also closed at about 14:00 UTC.

One thing I did notice was that one the Sporadic-E faded away, the propagation on the other HF bands like 17m, 15m and 12m really died as well. With the solar flux down around 70, the higher HF bands are very dependent on Sporadic-E for any propagation at the moment.

These are the FT8 signals heard on 28 MHz...

The propagation seemed a bit more southerly than previous days favouring the south of Germany, the north of Italy and Spain.

Only one double hop Sporadic-E signal was heard and that was in Ukraine.

There were some very weak signals later in the day but I didn't have the software running. South America? I can't be sure so I'll have to go with what I did hear for sure.

These are the beacons heard...

PSKReporter website passes 7 Billion reception reports

I noticed today (27th Apr 2019) that the PSKReporter website has just passed seven billion reception reports!

I can see from previous posts that I had that it passed four billion around the 21st of July 2018 and five billion around the 28th of November 2018.

The vast majority of those reports are of course FT8 and it just highlights once again how popular it is.

Small opening on 28 MHz on Sat 27th Apr 2019

Saturday the 27th of April was a day when the 28 MHz band barely opened. It's easy to look at the map below and think it was a reasonable day but the vast majority of those signals were buried in the noise.

Looking at the PSKReporter website, the main Sporadic-E opening was over northern Europe centered on a region over the north of Germany and the south of Sweden. I could hear lots of weak signals and it certainly felt like I was on the edge of the opening.

In the afternoon, the only loud signals were from Iceland which were there for a few hours.

In the evening, the band opened to South America but the signals were really weak.

I listened several times during the day for beacons or other signals on the band but heard nothing.

These are the FT8 signals heard on 28 MHz...

The mysterious signal of KI5BLU on 28 MHz... 26th Apr 2019

Two days ago while listening to FT8 signals on 28 MHz, I heard the signal from KI5BLU in Texas... or so I thought.

On the 26th of April 2019, I saw the signal again while the band was open to South America. Note that the trace shows KI5BLU in Texas (locator square EM12). Note that I have Puerto Rico marked ...more later.

This is the traffic that I recorded on FT8 which shows KI5BLU working Ireland, Wales, England and Germany on 28 MHz...
160630  -1 -0.1 1058 ~  EI8GS KI5BLU EM12
160645  16 -0.3 1224 ~  KI5BLU EI8GS -01

163645  -7  0.1  924 ~  DK4CF KI5BLU EM12
164400  -7  0.1  754 ~  <...> KI5BLU EM12

Suspicious...
If this was 14 MHz or even 21 MHz, I would have thought nothing of it. But this was April at the bottom of the sunspot cycle. East-West multi-hop Sporadic-E from Ireland to Texas on 28 MHz would be unusual this early in the season.

I then checked on PSKReporter to see who was hearing KI5BLU over a three hour period...

I then selected several of those... AM70E in Spain, G4HZW, G0LUJ, 2E0XXO, G8IXN and G7KFQ in England, MU0WLV in Guernsey, EI8GS in Ireland and F5OIH in France. I then checked what they had heard over a six hour period.

All nine stations as well as myself had heard KI5BLU but had not heard a single other station on FT8 on 28 MHz from the USA.

It's safe to say that KI5BLU was not transmitting from EM12 in Texas.

Initially I thought he was using a remote station as suggested by his QRZ page.... " Elecraft K3-mini for remotehamradio.com"

After a second search on Google, I found this...
KP4/KI5BLU - Palmas - Puerto Rico 04-22-2019
Thomas, KI5BLU will be active as KP4/KI5BLU from Palmas, Puerto Rico, IOTA NA - 099.
He will operate on HF Bands. QSL via KI5BLU, LOTW, eQSL.
Link

This would certainly tie in with the propagation paths that would seem likely to Europe on 28 MHz at the time. The problem is that he is giving out his locator on FT8 of where he lives in Texas rather than where he is in Puerto Rico. He was also not using the KP4 prefix.

This is what confuses people into believing the band is open to the USA when it's obviously not.

RTE radio service on 252 kHz to be extended

The RTE radio transmitter on 252 kHz on the long wave band has been flagged for closure for many years as there is adequate coverage on the FM VHF band around Ireland.

A sizable Irish diaspora in Britain however campaigned for the service to continue as many elderly people don't have internet access.

Located near Tullamore, it is one of the few radio stations transmitting on the long wave band. It does however suffer from a lot of interference from an Algerian radio station operating on the same frequency.

According to an Irish Times article in 2017, the service had been extended to 2019.

It now looks as if the mast is going to be upgraded and it will continue for another two years at least.

See the statement below dated Thurs 25th April 2019

More Sporadic-E on 28 MHz... Fri 26th Apr 2019

For the third day on a row, there was another good Sporadic-E opening on 28 MHz. It was perhaps a little bit more patchy than previous days but there was a very good opening to South America.

This is the world map of the FT8 signals heard on 28 MHz on Friday 26th of April 2019.

The station KI5BLU shown in Texas was almost certainly not there and was giving out the wrong locator. See other post.

The opening lasted from about 09:30 UTC to as late as 22:30 UTC and the band was pretty much open for all of that time.

During the day, the coverage was more patchy than previous days. It did open to the south towards Spain but it wasn't great. It seemed much better towards the east for most of the day.

The beacon in Greece was double hop.

This is a closer look of the European stations heard on FT8 on 28 MHz...

Note the yellow line showing the rough limit of one Sporadic-E hop from my location.

There was some small amount of double hop into Greece, Ukraine and Russia. The suprise opening though was towards South America and the Carribbeean.

A list of stations heard on FT8 is shown below with those over one hop distance shown in bold...

Another big Sporadic-E opening on 28 MHz - Thurs 25th April 2019

There was another big Sporadic-E opening on 10-metres on Thursday the 25th of April 2019 and the band was pretty much open all the time from 08:30 UTC to 21:00 UTC.

It was pretty similar to the opening on the 24th of April except there seemed to be a bit more double hop Sporadic-E. These are the signals heard on FT8 on 28 MHz...

I have included a yellow dotted line on the map to show the extent of one hop Sporadic-E from my location on the south coast of Ireland.

As you can see, there didn't seem to be any double hop in the direction of the Baltic states of Estonis, Latvia and Lithuania. Further south though, there was double hop into the Ukraine, Russia, Romaniam Bulgaria, Greece, Turkey, Israel and Egypt.

I heard one lone signal from South America although I know others in the UK heard a lot more from there. I have a large hill to my south-west which blocks low angle signals from that direction.

These are the signals from Europe in more detail. Look at the big numbers in Germany!

Germany at 1000 to 15000 kms is pretty much the ideal distance for Sporadic-E from Ireland.

Like the previous day, I missed an hour or so but I think I caught most of what was there to be heard. In total, I heard 1163 stations in 47 countries which is pretty remarkable if you consider that it's 28 MHz.

Big Sporadic-E opening on 28 MHz - Wed 24th April 2019

After a quiet week and a half, the 10-metre band burst into life on the 24th of April with an extensive Sporadic-E opening. This is the world map of what I heard on FT8...

There were a few unusual signals in there.... Israel, Burkina Faso, Mauritania, Trinidad and Texas! Also heard but not shown was a station in Cyprus.

That one from 'Texas' was a real surpise but see the explanation here.

The band seemed to open at about 10:30 UTC and lasted until about 22:00.

What was unusual was just how long the opening lasted and how extensive it was. Usually with Sporadic-E, the footprint of the opening moves around. With this one, the band just seemed to be open all over Europe.

I was in a mini pile up for the Spanish AM70 stations on CW and I could heard people all over Europe calling them. It took a bit of work to get through in the end which just goes to show how many people they were hearing at once.

This is the European map of what I heard on FT8...

The ones of interest here are those in Sicily, the end of Italy, in Crete and in Greece. These were all double hop Sporadic-E.

I wasn't listening on FT8 all day, just most of it. I probably missed maybe 1-2 hours made up of small breaks. There were probably a few extra that I could have added if I was on FT8 all day.

These are the beacons heard...

Always nice to hear the beacon from the Faroe Islands as it's a bit unusual.

Looking through my logbook, the contact with AM70S on CW was my first contact on 28 MHz since May 2018! I guess I listen a lot! :o)

Sporadic-E on 28 MHz - Tues 23rd April 2019

There were a few weak Sporadic-E signals today on 28 MHz. Now nine days since the last decent opening.

The one notable signal was that from EA8WU in the Canary Islands at 20:25 UTC and well after sunset. I'm assuming it was double hop Sporadic-E?

New FT4 protocol announced for Digital Contesting

On the 22nd of April 2019, a PDF document was released outlining the new FT4 Protocol for Digital Contesting. Link.... http://physics.princeton.edu/pulsar/k1jt/FT4_Protocol.pdf

Key points...

1) Transmissions last for 4.48 seconds as compared to 12.64 s for FT8.

2) Works at about the same speed as RTTY for contesting.

3) For a rough comparison with RTTY, it was noted that in simulated mid-latitude moderate conditions RTTY has been shown to yield character error rates less than 10% only when SNR exceeds –1 to +4 dB, depending on the software modem in use. FT4 offers a sensitivity advantage of about 10 dB over RTTY.

4) As many as 50 stations can operate in a 3 or 4 kHz passband with little interference, even when signal strengths differ by as much as 60 dB.

5) July 15th 2019: General Availability (GA) release of WSJT-X 2.1.0 and FT4.

From the document..."FT4 is a special-purpose mode designed for rapid-fire contest QSOs. It serves this purpose very effectively, but like FT8 the mode is not useful for more extensive conversations. FT4 uses much less bandwidth than RTTY and provides reliable decoding at much lower signal levels. Stations using low power and compromise antennas can participate effectively in a contest using FT4."

Thoughts... 
It will be interesting to see how this develops and what impact it will have. Will it help kill off RTTY? Will it be used outside of contests?

The software can be downloaded here... http://physics.princeton.edu/pulsar/k1jt/wsjtx.html

Update... See this video presentation about FT4 from Joe Taylor K1JT. The piece about FT4 starts around 14 mins...

New 434 MHz to 2.4 GHz Transmit Converter

The new OSCAR 100 satellite in geostationary orbit has a downlink in the 10 GHz band and an uplink at 2.4 GHz.

I was looking through the most recent edition of the Dutch Kingdom Amateur Radio Society  magazine and I noticed this transmit upconverter...

The price seems pretty modest for what it does although I don't know anything about its performance.

From what I understand, something like 2 watts into a 2.5-3 metre dish or 10-20 watts for a 1-1.5 metre dish is required for an SSB signal for the uplink at 2.4 GHz.

For more information, go to http://www.dxpatrol.pt/

Poor conditions on 28 MHz on Sun 21st Apr 2019

The last seven days of this week have been pretty poor on 28 MHz and I wouldn't consider any day to be good. That is in marked contrast to last week when there was reasonable Sporadic-E on five days out of seven.

My own date to watch is always the 23rd of April. It just seems to be a day when there is often an opening on 10m and 6m. This may have something to do with the fact that the Lyrid meteor shower peaks on the 22nd of April and that meteor dust is a vital component in the formation of Sporadic-E in the following days.

This is what was heard on FT8 on 28 Mhz on Sunday the 21st of April

Weak opening on 28 MHz - Sat 20th Apr 2019

Conditions on 28 MHz for the last two days have been poor although Saturday seems to have been the better day.

Friday 19th April 2019... I wasn't able to monitor 28 MHz on Friday the 19th of April but looking at the PSKReporter website and what some of the regulars in the UK heard, it seems like it was pretty dead.

Saturday 20th April 2019... There were a number of FT8 signals during the day although not a great amount. The signals were pretty weak as well.

The most interesting signal was probably that of EA8EE in the Canary Islands at 2733 kms. It was most likely double hop Sporadic-E.

Looking at the PSKReporter website, it looks as if some stations in the UK were hearing South America but there was nothing here.
