I don't think it's your problem, Jim. Okay, well thanks for the comment back on that. I'm using a switcher, a switcher power supply. It's relatively new, less than a year old, and it's the brand is pyramid, and I just run the 12-volt output from it to my transmitter fever, and so that's how it's working. Right, and that switching power supply probably switches at 200 kilohertz or something, so you should not hear a 60-cycle hum because it shouldn't be there at all, regardless of what's going on. I think it's coming from somewhere else. Okay, well thanks for the heads up. Anyone else, any topic whatsoever?
