10m Tenbox QRP transceiver

Posted: 21 Aug 2021 03:17 AM PDT http://g3xbm-qrp.blogspot.com/2021/08/10m-tenbox-qrp-transceiver.html


Because of my poor health, progress on this project stopped. It would make
an ideal winter project. It is designed as a local natter box, ideal for
local nets. It is not intended for DX.

Posted: 21 Aug 2021 01:15 PM PDT http://g3xbm-qrp.blogspot.com/2021/08/10m-ft8-rx_21.html


Now I am back home, I am on 10m FT8 RX again. 64 stations spotted with the furthermost 4Z5LX (3633km) in Israel.UPDATE 1314z: 181 stations spotted
today on 10m FT8 RX including 2 in Newfoundland, probably Es.
UPDATE 1955z: QRT soon. In all, 237 stations spotted today on 10m FT8 RX
(see map).
UPDATE 2008z: Now QRT with 240 stations spotted today including LU1HW (11230km) in Corduba, Argentina. He was very strong, but too late to be
shown on the map. This was the best DX today. When I went QRT there were
still South Americans coming in.

Rally and BATC ATV Convention

Posted: 20 Aug 2021 11:30 PM PDT http://g3xbm-qrp.blogspot.com/2021/08/rally-and-batc-atv-convention.html


In the last few days I have been reminded of the following:On this Saturday August 21st is the BATV Convention. You may recall the date has changed.
One person missing will be Ian G3KKD who died earlier this year. He was a
keen ATV man.On Sunday August 22nd is the Grand Field Day Out at
Willesborough Windmill, near ashford in Kent.

As usual, I'd made sure these are on before setting out.
