CV1931 update

For some time I had a CV1931 on the website, the example being a 6H6 metal double diode, though not 6H6 marked. Today I got a glass CV1931, also marked 6H6GT. I never checked before but the metal one is clearly incorrectly marked.

The CV Register has three CVs in a  series: CV1929 / 6H6G, CV1930 / 6H6 and CV1931 / 6H6GT. This makes sense.

For now I’ve left the page as-was but added the glass valve.

 

Amateur radio

I’ve had an interest in amateur radio since I was young. I’ve had all sorts of radios, built radios, wired all manner of aerial but never got round to taking the exam. Then the exam changed from the old class-B / class-A business to the new foundation/intermediate/advanced. Still I never took the exam.

Then I got interested and decided I would. So I wanted to find out where I could take the foundation exam. I contacted a large society and got nowhere. I tried the local clubs and never got an answer. So I gave up.

I just decided to look again. Apparently the nearest clubs where I might take the exam are at least 10 miles away and meet on evenings when I am busy. One club has a calendar, the latest event in which is some time back in 2013.

So I won’t bother…
