Corfu Beer

Posted: 22 May 2022 09:01 PM PDT http://g3xbm-qrp.blogspot.com/2022/05/corfu-beer.html


So far this week, we have had blue skies and warm sunshine and a very
pleasant heat. A cold beer has been very welcome.

8m beacons

Posted: 22 May 2022 08:53 PM PDT http://g3xbm-qrp.blogspot.com/2022/05/8m-beacons.html


There is a growing interest around the world in the 8m band for propagation research.
The band is between 10m and 6m, at the transition between HF and VHF.
Sadly, the few beacons there are there are on different frequencies and
modes.
In my view, they would be far more use if they all included an FT8 sequence
and were all on a single USB dial setting (different audio tones so they
are not on top of each other). They could be on 24/7 and widely monitored
with ease by many.
Personally, I think we would all benefit from this. Propagation research
would be greatly advanced.
FT8 works with weaker signals than CW, WSJT-X software is free, and even
very brief openings get spotted.

Ultra simple RX for 80m or 40m

This is one of the most simple designs that you will ever find for 80m or
40m RX. It will readily scale to 160m or 60m. I went on to make a
transceiver version based on an idea from W2UW (SK). Imagine that - a
complete transceiver using just 1 FET (see the FETer).

John's blog always seems to have interesting stuff on it. He has news of
the 40 and 60 MHz bands as well as much more. On the web version of my blog
is a link to the EI7GL blog is on the right.
