Tonight I had my first QSO on the Brendon DSB radio! I was talking to LA6GOA/M on 3.670MHz and received 59+ without the linear! The distance was not very far, just a couple of hundred metres. This is pure QRP fun! I have a minor problem that I need to sort out: The audio disappears from time to time on both TX and RX. I will have a look at this later.
