Has anyone investigated building a receiver as a plug in peripheral to eg an IBM PC or Mac, etc? I'm curious as to whether the major problem would be noise radiated into the frontend, or if power supply carried noise would be the problem. Rick Spanbauer, WB2CFV State U of NY/Stony Brook

I've hooked P.C's up to scanners and written programs to switch banks and load banks with pre-stored frequencies before..and it hasn't been a problem...although the scanner has been equipped with the necessary inter- facing. Are you thinking of some form of sampling set-up using a series of D/A and A/D converters? The only time you'd get problems from a radio receiver causing problems is if the IF sections are not shielded..and I'll bet that would be a very hard item to find these days. Just make sure that you are supplying the radio receiver with power from the computer's supply. Using an external supply is just asking for trouble. -Mike N7GYX

Both an FM broadcast receiver and a television broadcast receiver are available as boards for the Mac II. I think it silly. I did see the "Micro TV" board in action at Computerware today. It's supported as a desk accessory, and you can watch TV with a 2x2 window devoted to the TV screen. Supposedly you can do this while doing other things, but our attempt to watch TV while running Model Shop crashed the machine immediately. Incidentally, the on-screen TV image is monochrome, even on color displays. John Nagle
