[net.ham-radio] Computer Noise

brosen@BBN-SPCA.ARPA (Bruce L. Rosen) (11/20/85)

I received my AIR-ROM for the Commodore 64 yesterday, and was up very late
copying a variety of previously un-copiable RTTY stations.  The AIR package
seems to work pretty well.  My only quibbles so far are that its Autostart is
too stingy in my estimation, and that it doesn't seem to remember what Baudot
speed had been set prior to going into ASCII mode.  When you come back into
Baudot mode, you need to reset the speed if you want something other than
60WPM.

However, I have now experienced having a computer in the ham shack for the
first time.  The C64 seems to produce incredible amounts of noise, which the
receiver (an HQ-180) picks up over the entire spectrum (or at least the part
that I listened to last night).  I am looking for advice on how to quiet it
down.  Your personal experiences or references to QST articles would be much
appreciated.

Thanks!!   Bruce (K1FFX)
