I wonder if you're thinking of the Knight Broadcaster - Someone is selling a reproduction kit of it on eBay. There's also a tribute site, with p...

I'm not quite sure how the Heathkit DX-60 fits into this discussion. It was capable of putting out 90 watts of AM on the ham bands from 3.5MHz thru 28...

@richpowers - after making a few of my more convoluted, unfocused, and technical posts in this forum, I sit back, look at them, and think, "Well that ...

Thanks for the correction @richpowers. I need to go back and read your posts in this thread in greater detail.

Wow. That's an awful lot of information to take in Rich. Interesting that the Little Wonder Microphone, and products like it, were the first reason fo...

@mark Interesting demo. I had heard of Sean Cuthbert, due to his AM stereo transmitter. I didn't know he also had an audio processor. Thanks for the i...

@richpowers I completely understand. Once it's gone, it's gone. If I were in your position, I'd take plenty of time before making a decision. In the m...

@richpowers - if you ever want to sell your SSTRAN, let me know. I decided a while back that I'd buy an AMT3000 (or 5000) in almost any state, workin...
