<Posted for a friend> I have an IBM PC/AT 12 mhz compatible, and a Leading Edge XT compatible. I plan to use both for various amatuer/shortwave radio applications. However, both machines now generate enough RF noise to drown out all incoming signals. A few questions: 1) The rcvr Im now using is fed directly with a random-wire antenna. I plan to upgrade to a decent xcvr. With this will of course come an antenna fed with coaxial cable. Will this elimiate/reduce <significantly> the amount of noise? 2) If that doesnt work, are there any relatively cheap/easy ways to modify the computers (some form of shielding perhaps? they're already in grounded metal cases) to produce less noise? Again, for what I plan to use the computers for, they will have to be on simultaneously with the radio.. so shutting one down until Im done with the other is not an alternative.
