Thank you, Mike. I think it is satisfying any time you take something not working and make it work again. This is the most complex radio I've worked on and is especially satisfying to get it working so well, especially without major problems of my own making!

The FM converter is working very well. I am enjoying listening to music on various local FM stations from classical to rock and from my own FM transmissions streaming from my DAW. Interestingly, the audio from my HiFi AM transmitter sounds indistinguishable from the FM sound when I have the AM selectivity in the broadest position. FM is a tiny bit quieter. The AM transmitter is not really a transmitter, rather a micro AM rf source modulated from about 20 Hz to 15 kHz. I can connect it directly to the AM antenna connection of the radio and disconnect the long wire to eliminate outside AM signals. All of the HiFi AM radios sound great, including the Philco 37-116, from this source.

Perhaps I'll make a couple of videos to show the AM portion including the short wave bands, the FM with the converter, and, perhaps, demonstrating the variable selectivity control - how it works, how it changes the sound, and how it affects selectivity. I'm just not much into videos! Maybe I can Buzz to help!!
