Please watch this - NOT amateur radio

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.

Meal out - NOT amateur radio

As our son was 44 earlier this week we took him out for a nice meal as he was here overnight.

Amazon and amateur radio

Amazon is a bit like the UK yeast spread Marmite: you either love it or hate it!

My wife and I really try to support local, village businesses. As our son tells us, without our trade they will just go. The local butcher does amazing bacon and the local bakers great soft rolls and pasties.

I digress. What I was going to say was that Amazon does a great range of amateur radio products and books. With Amazon Prime you can order these for next day delivery.

Our shopping habits are changing and many choose to order from the armchair and get them delivered to the door the next day. OK, we cannot browse as we can in a real shop, but returns are easy and painless.

I was saddened by our local chemist: last year my wife just wanted some nail scissors. Nothing fancy, just simple nail scissors. She was told they had no stock and were not getting any! She went on Amazon, ordered them and they were delivered promptly, for less money! If local businesses are to survive they have to stock common items at sensible prices. Many people will pay a little more to shop locally.

Indoor loop matching

Normally, loops are matched with a primary winding about 1/5th the size of the main loop. In my case the matching is done using a tapped toroid tuned circuit. This matches the loop on 20m, 17m, 15m, 12m, 10m and 6m.

The wire used in the loop is about 1mm diameter and the loop diameter about 45cm across. It just sits on my shack windowsill. It works far better than I ever expected.

As I mentioned before, if you cannot use an outside antenna and you enjoy modes that don't require lots of retuning, consider a loop!

2m FT8

A few moments ago I went on 2m FT8 again. As usual, I am using 10W to the big-wheel omni antenna. On 2m FT8 RX 2 stations in 2 countries spotted and on TX I have been spotted by 7 stations in 2 countries so far.

UPDATE 1028z: Now spotted by 11 stations in 4 countries with best DX a spot by EI3KD (583km) in or near Cork.  One QSO so far with M0NPT (125km). On 2m FT8 RX, 3 stations in 3 countries spotted so far.

UPDATE 1128z: Now 6 stations in 4 countries spotted on 2m FT8 RX today so far.

UPDATE 1242z: Now 15 stations in 6 countries spotting my 10W 2m FT8 TX today so far.

UPDATE 1540z: Now spotted by 22 stations in 6 countries on 2m FT8 TX (10W) as the map shows.

UPDATE 2323z: Now QRT. In all 36 stations in 7 countries spotted my 10W FT8 on 2m today.

Chestnut tree - NOT amateur radio

A very long time ago a couple of horse chestnut trees were planted in our churchyard to celebrate the battle of Waterloo in 1815. The photo shows one of the pair with rooks busy nest building!
