When clearing some old photos yesterday, I cam across this photo of the
shack in 2015.
How time flies!

10m QRP TX (Thursday)

Posted: 28 Apr 2022 03:33 AM PDT http://g3xbm-qrp.blogspot.com/2022/04/10m-qrp-tx-thursday.html


Yet again, I am on 10m WSPR TX with the W5OLF beacon. So far just local
G4KPX (14km) spotting me.
UPDATE 1033z: Just local spots still. I think even Richard has given up!

80m FETer transceiver

Posted: 27 Apr 2022 02:25 AM PDT http://g3xbm-qrp.blogspot.com/2022/04/80m-feter-transceiver.html



It seems like yesterday, but this was designed in 2008. Starting from the
40m design by W2UW (SK) I wanted to see how simple a transceiver could be
made for 80m. The result was the 1 FET FETer transceiver. My main issue was netting on RX.

Posted: 27 Apr 2022 09:18 AM PDT http://g3xbm-qrp.blogspot.com/2022/04/10m-qrp-wspr-tx-wednesday.html


As my 10m antenna is again available, I am on 10m WSPR TX with 500mW from
the W5OLF beacon. So far just 1 spot by TA4/G8SCU (3010km).
UPDATE 1617z: Just 3 unique stations spotting me all day. Nothing further
than the TA4 above.
