Doug built a really beautiful receiver, but reception was marred by a bad hum. It was quickly determined that this was caused by a noisy "wall wart" located close by. A re-location of the power supply remedied that, and allowed Doug to pull in some really nice signals.

Had a lot of fun doing this over the past couple of weeks. Not my first DC receiver build--I built a Neophyte Receiver from QST years ago--but this one was the most fun. Thanks Bill, Dean, and the whole DCR challenge community--I'm learning a lot in my old age!
I'm a retired pastor who's been fiddling with radio stuff since about 1991, and though I've been inactive for long periods of time, I've always enjoyed QRP and homebrewing (and I've built a bunch of kits, too, including my main rig, an Elecraft K2). It's been a while since I had a halfway decent antenna up, but that's in the works. As a boy I was at my dad's side in his modest shack whenever he was building or operating (he was K8LZO back in the day), and one day while listening to shortwave broadcasts during the first Gulf war, I tuned around and heard some CW signals and decided it was time to learn the code and get my license. Anyway, this project has been a hoot, and I so appreciate all of you and your generosity with your experiences and experiments and successes and failures. Thanks! 73, Doug, AA0MS
Congratulations Doug and welcome to the Hall of Fame.
