Hi. Looks great and works well. Nice to have a contact here as well as on air. I just have to point out one tiny thing, the diodes are 1N4148 and not IN4148. Just a tiny thing. Don’t have one of these wireless but have been looking around. I really like all your videos. Keep up the great work and congratulations on the portable to portable UK contact. So exciting to listen to. Look forward to another QSO on air. Best wishes for the season and the new year to you and your family. 73s Richard VK2VD
Unfortunately, I don't trust these types of circuits. The main reason for this is that they only switch when the high frequency is present and it also takes some time to switch the relay. During this time, the SWR load of the final stage increases. Instead, I prefer the PTT line. Anyway, good luck, and happy new year !
hi, nice video and circuit. I did try to make a auto switch, but i was lucky to have the amp switch on my ts 480hx, which simply connects the power across the relay, the switching line has no power on it from the rig, so no sensing circuit required, its just simply a switch .it seems to work ok, although i am not sure, if i should have other components onboard for protection. sent you the circuit via email, if you could comment on it, would be very much appreciated. cheers. brian zl3xdj.

👍Looks good, thanks for sharing.
Nice job
Awesome …. Thanks for sharing!
Hi Alex. would this work with 12v relays for a non clansman radio or would you have to redesign it. Thanks Brian 2e0tcu.
