I have been working on the soldersmoke DC receiver in between batches of good weather and the weather has been unseasonably good, so it has been a little slow. I finished the audio amp a couple of days ago, and put all the boards together today. It works, more or less, but I miswired the transformer on the RF side of the double balanced mixer and have to fix it before I can declare victory. ?

That's a neat-looking build Bill. I like the yellow trimmer capacitors in the BPF. I have a number of those that I got from Dan's Small Parts and Kits. They are 65pF, and Dan sells them for a dollar apiece. Not as cheap as the little 6mm economy trimcaps (including the "little brown buggers" to quote another group member!) but they are eminently more satisfying to use. They even have vanes that you can see - like a real variable capacitor! :D

Hope you manage to get the DBM transformer rewired correctly.
