Graham was another good sport. When I asked him about the receiver, he had already moved on, and — is often happens — had separated the stages and replaced some of them. He agreed to put the receiver back together and to shoot a video of it in action. Above you can see it, happily inhaling SSB from nearby Spain. He used a different AF amplifier cicruit — that is why this is in the Honorable Mention catergory.

It has been an interesting exercise as I’ve tended to use active mixers before, but I think I am converted to DBMs now. The other rx I’ve been working on with a VCO is performing very well. I need to move the preamp over to the PTO one and see how it performs.
Thanks Graham and congratulations.
