Colin's FB Rig

Hi Bill,

I'm still enjoying your podcast very much - I have the T-shirt to prove it!

My parents bought me SolderSmoke the book for
Christmas and I must echo other people's comments that it is very good and the explanations you give make a lot more sense than those in other technical publications.

Listening to your podcast got me thinking about radios again and I have nearly completed my first homebrewed transceiver project. It's all YOUR fault! I had a spare RockMite keyer chip in my junk box, so I thought I'd use it........... Take one small keyer chip and......... build a whole
new radio!

Okay, I used Dave's (K1SWL) schematic, but I did not use any
printed circuit boards and I have made some modifications to the circuit. I think I can class this as homebrew. I even made the twin paddle key! The only thing I didn't make from parts are the earphones, see http://www.flickr.com/photos/24901892@N03/5833428467/ There are more photos on the Flickr site too.

Looking forward to the next edition of the SolderSmoke podcast.

  2. Colin,

    That is super thick PC board. I have similar board that makes nice bottom for VFO's. I have trouble cutting it though. Nice work on your project. You are a member of a very small group...those amateur radio or electronics enthusiasts who actually scratch build a receiver. It can be exciting.
