XBS Telecom

This EU company seems to offer very good prices with VAT added and good guarantees. I have never used them, so have no experience. If other have, perhaps they could share their experiences here.

It is interesting that many dealers are now offering the ICOM IC7300 with free gifts. It appears that ICOM are resisting dropping the basic unit price.

20m FT8

A few moments ago I went on 20m FT8 with 10W to the tiny indoor loop.

It is now 1426z and 36 stations spotted on RX and just 1 spot on TX by II0IDR (1442km).

UPDATE 1450z: No other spots of me on TX. When a strong signal appears I can get swamped. I have just moved about 100Hz LF to see if that makes a difference. I always check I am on a clear spot, but this does not always work!

UPDATE 1725z:  Now spotted by 18 stations across Europe.

Webcams - NOT amateur radio

It seems possible that some of the next few months we will be stuck at home under quarantine. Thank goodness for webcams!

Earlier today my brother was in Devon at Buckfastleigh at the South Devon Railway. He alerted me on WhatsApp so I was able to see him on the platform with his grandson. There are plenty of other webcams around the world. Some are live.

New life - NOT amateur radio

Every year the daffodils in the churchyard look a picture giving us hope of spring and better weather. In these Covid-19 filled times it good to see nature getting on with life.

Sunspots - Sunday March 15th 2020

Solar flux is 68 and the SSN 0.  A=3 and K=1.

Solar flux

For the last few days we have seen solar flux numbers in the sixties. In February, unless I am mistaken, numbers were in the low 70s. Perhaps we have not quite reached the solar minimum yet? We may just be bumbling along the bottom.

More on loops

At our old house, I did some tests with a loop antenna using central heating pipe.

More recently I have been using a Wonder Wand loop that was a gift many years ago. As described yesterday, this loop uses a different way to match the loop and much thinner wire for the loop. Thicker wire results in better efficiency and sharper tuning. As I recall, my loop of some years ago was surprisingly effective.

For 10m FT8 the loop could be brought to resonance with a small length of coax. This needs to be carefully cut to tune to frequency, but once cut, it should not need further adjustment. A short length of coax acts as a capacitor and should be able to cope with the high voltages at the top of a resonant loop.

Pre-theatre meal - NOT amateur radio

Some months ago we went to the theatre in Wembley. The photo shows me eating a pizza before the theatre.

I was told of these videos from Dr John Campbell by Chris M0PZC. The "delay" phase is trying to reduce the peak of the coronavirus pandemic, so that health services are better able to cope. This is to help the community.

Children, in general, are not badly affected, but they can spread the disease. Older people with pre-existing health conditions can become seriously ill and die.

Your help is imperative. Do what you can to slow the spread of the virus. Thank you. Your actions could save lives!

With a vaccine readily available being some way off despite great effort, our best hope is some antiviral treatment that may improve outcomes. From what I have read, the best hope is remdesivir, although I am no expert.

20m FT8

In a short while, I shall go on 20m FT8 with the tiny indoor loop antenna. Results previously have exceeded expectations.

UPDATE 1118z: I have turned on the 20m FT8 (10W). Already 39 stations spotted, but no-one has spotted my yet. I maybe am (unknowingly) co-channel with a strong signal inaudible here. I checked the frequency before TXing.

UPDATE 1230z: Since moving about 200Hz HF I have been spotted by 18 stations! Best DX is a spot of my 10W by N4PSK (4374 miles). On 20m FT8 RX 145 stations have been spotted so far.

UPDATE 1920z:  Still being spotted! 111 spots of me today and 7 in the USA.

UPDATE 2129z: 121 spots of me today on 20m FT8 with the tiny indoor loop and 10W as the map shows. Several 2-way QSOs too. Now QRT.
