20m FT8

On the tiny indoor loop 614 stations spotted in the last day on 20m FT8 RX, well exceeding all expectations.  Already on 20m FT8 RX with the loop lots of stations spotted. This is far from a great loop as the wire is not exactly thick. Quite amazing.

Today I might try a higher HF band.

Trump Impeachment - NOT amateur radio

Whilst I fully accept that the good people of the USA are free to elect whoever they wish as their president, I personally have problems with President Trump and PM Johnson.

Both men seem to me (personal view and others are free to hold different views) to be right wing and rather poor in their roles. President Trump seems to me to be out of step with many e.g. over climate change and Iran to name just 2. His actions seem to fall short of what I'd expect from a true statesman. PM Johnson seems to be in a similar vein.

We'll see what the impeachment enquiry into the activities of President Trump reveal.

All I ever wish is that leaders of the western nations act as true statesmen, thinking long-term and not about their own careers. I struggle to think of any leaders who are more focussed on the long-term good of the planet rather than their own short-term well beings.

20m FT8 RX

As I have no antennas outside for 20m I am using the tiny loop on the back of the rig indoors. At a guess this is about 0.5m across. In the first 2 hours no less than 97 stations spotted with best DX EA8AT (2843km) in the Canaries. This antenna is so small and indoors.

UPDATE 1533z: Quite amazing. 373 stations in 4 continents spotted today on 20m FT8 RX with the tiny indoor loop. Best DX spotted is JF8QNF (8763km).

UPDATE 1542z: As an experiment, I tried a quick 20m FT8 CQ (10W) using the indoor loop, but was spotted by no-one. I may try again as there is a high chance I was being clobbered by another station on the same frequency.

UPDATE 1727z: For some reason, my 20m dial had moved to 14.000 rather than 14.074MHz. I called FT8 CQ again (this time on the correct frequency) and was spotted in southern Italy by 3 stations and 1 in France. On RX 465 stations spotted on 20m FT8 with the tiny indoor loop today.

UPDATE 2140z:  584 stations spotted today on 20m FT8 RX with the tiny indoor loop. I have to say that results with this tiny antenna have far exceeded my expectations.

PSKreporter issue?

All morning nothing I received was being reported to PSKreporter maps. I restarted the PC and checked WSJT-X was working on 20m RX. Locally lots of EU stations are being received, but nothing is appearing on the maps. Time was just resynced and as far as I can tell my internet connection is working. I am beginning to wonder if there is a problem with PSKreporter getting reports.

UPDATE 1011z: All now working. Mystery.

2m FT8

Although I called CQ (10W) on 2m FT8 earlier, just a couple of people spotted me (EI and G) and no QSOs resulted.

On RX it was a similar story with no spots yet. It appears that many stations get active with FT8, find out the ranges are incredible, then give up having worked those stations that are active.

By the end of the day, there are usually plenty of stations and countries logged on 2m FT8 RX and TX, but I get the sense that 2m FT8 is beginning to go "off the boil" and activity levels are now dropping.

Perhaps those that get on FT8 go to work, so only get on in the evenings mainly? Certainly early mornings are not that productive.

The Outer Hebrides - NOT amateur radio

One of the places I have never been to is the Outer Hebrides in western Scotland. Having read about  these quite a bit,  it is now unlikely I'll get there.  There are miles of white sand in the Hebrides, but few trees because of the winds. Much of the coast has wild flowers.

Barra in particular takes my fancy. This is one of the southernmost islands and the plane lands on the sand twice a day.

Heathkits

Like many of my generation, I loved Heathkits. The very first thing that got me into the hobby back in 1961 was an Electronics Workshop. In the late 1960s, I wanted a 2m HW30 Twoer AM transceiver.

According to their website Heathkit was making a comeback. Their website exists, but their product range is very limited and very overpriced. If it still survives, it must depend on a very loyal customer base. Certainly, I would not buy these. If the comeback was successful, I'd be surprised.

G6ALB's (mainly valve) website

For years I had regular QSOs each week with G6ALB in the next village. It looks like his website has not been updated since 2009! If you are "into" valves, you may find some ideas here.

ISWL

Way back in the 1960s, and again much later, I was a member of the International Short Wave League (ISWL). In the 1960s it was quite a large international organisation producing a monthly magazine called "Monitor".  At that time, years before I was a licenced amateur, it had a tapesponding section and I exchanged tapes with an SWL in N.W. USA near Seattle. This continued for several years. I do not know what happened to him.

I think the ISWL still exists (just) but when I left for the second time many years ago it was down to a few hundred members. The ISWL was unique in that it catered for broadcast listeners as well as amateurs.

If it still exists, I would expect it has very few members left. If anyone knows how it is today, please let me now. I left for the second time as it ceased to meet my needs. The website still exists, but it looks the same as it did many years ago.

Another IC-705 video

This YouTube video was found this evening. I hope you enjoy watching it.

Wasted spectrum?

In the UK, great swathes of spectrum are reserved for the military. I have long argued that some of this should be made available for the amateur service on a strictly non-interference basis. Even a very low ERP level could be set and stations closed if there is any hint of interference. It seems this falls on deaf ears.

In the meantime, much of the spectrum remains unavailable for serious experimental work. In no way am I saying such spectrum should not be available for the UK military as the primary user. But surely, under NoVs, parts of the spectrum could be opened up for serious "radio science" work? A phrase like "p***sing in the wind" come to mind. As commercial gear is not available at many of these frequencies, only serious experimenters are likely to apply for NoVs. Numbers would be small and all addresses known. We could even be asked to notify someone before experiments start.

Autumn leaves - NOT amateur radio

For several years now my wife has taken a photo of a certain tree at nearby Anglesey Abbey. We went this morning to catch it in its autumn colours.

After a few more weeks and with a decent blow, the leaves will have fallen until new buds appear in the spring. When we went last week, it was mostly green.

Although it was a dull morning, it looked better last year.

Trump: please read the facts!!! - NOT amateur radio

"The scientists are "virtually certain" that the global ocean has now warmed without pause since 1970."

The BBC reports on the latest news from climate scientists at the UN. Oh, sorry, this is all rubbish and just a Chinese hoax, says Trump allegedly. The world needs the USA and China fully engaged for the good of our children and grandchildren. For some nations, rising sea levels are a threat to their very existence.

Reading means you stop watching soaps on TV, tweet less, forget lobbyists from the gun and oil people and actually read reports. A true statesman does this and listens to knowledgeable and wise advisers.

2m FT8

Although I have been on 2m FT8 RX overnight, just 2 spots (1G and one DL).

I may try a 10W FT8 CQ call shortly. It seems few transmit overnight. Some start at breakfast time. I think these were both normal "flat band" conditions with the DL (who is regularly on FT8) via flat band tropo judging by the signal level.

UPDATE 1242z: So far today 13 stations in 7 countries spotted with best DX on 2m FT8 RX being EB1DJ (1279km) in northern Spain. On TX (10W to the big-wheel omni) an earlier CQ on 2m FT8 was spotted by 7 stations in 3 countries with my best DX DF6PW (562km).

UPDATE 1917z: A recent 10W FT8 2m CQ was copied by 11 stations in 4 countries. One QSO with PA1BVM (367km) resulted. On 2m FT8 RX 32 stations in 9 countries spotted in the last day.

CME triggered auroras?

Southgate News reports that there is a risk of a coronal mass ejection causing auroras this week. In the past I have worked stations via auroras with QRP on 6m CW and 10m SSB. A geomagnetic storm is likely even if the CME debris misses Earth.

Rybakov antennas

The basic idea of Rybakov antennas is to feed these at the high impedance end via a transformer so the impedance is brought down to the range (usually VSWR better than 3:1) that can be matched with the auto ATUs in many modern HF rigs.

Somewhere in the garage I have an x80 antenna which was a commercial version. I think this antenna is no longer available, but I guess similar antennas are available. The one I have was criticised for blowing wildly in winds. If I can erect it on our bungalow, it should give me access to several bands.

If you buy the toroid formers and wind the transformers, Rybakovs are quite easy to make. There are several examples on YouTube and elsewhere on the internet.

Back on air

The storm risk seems to have passed with both the BBC and Met Office weather forecasts showing no thunder and lightning this evening, so I have reconnected the rig, PC, PSU and antenna and have returned to 2m FT8.
