4m

This is a band that is gaining in popularity. It is very good when there is Es, but it is also good for inter-G working. I am sure that with reasonable power and FT8 the whole of the British Isles would be in range. The new Yaesu FTX-1F is supposed to include this in European versions.Β  I would expect 6W and a dipole to reach widely on FT8 especially.

A while back I designed and build a 4m transverter that is on my website. It is only low power but managed to work well. It was inΒ  GQRP SPRAT some years ago.

Smelling diseases - NOT amateur radio

Β When our children were young they had a "poorly smell". It was not unpleasant at all, but both my wife and I were aware of it. Maybe it is a parental thing that nobody else is aware of.Β 

Today I read of a nurse who has a remarkable sense of smell. She can literally tell if a patient has early signs of a disease by smelling their breath or even a swab. Her success rate is extremely high.

Crystal set DXing

Β 


Many years ago I tried making and using a short wave crystal set. It is on my website.Β  As you can see, it does not cost much to have fun. I had aims of making a crystal set that covered VLF to VHF. Then my stroke scuppered plans!

Short wave radio is changing and there are far fewer English language broadcasters. I was pleasantly surprised by what I could hear back then. It is not just broadcast stations you can hear.
