I love the XM weather and the approach plates as well as moving map but on the higher com frequencies the pc screen output causes enough electrical noise to make the radios hiss. I does not seem to reduce the receiver range much but just causes the radio to break the squelch limit. (like pulling the test button) My radios both do the same and one is an SL-30 and the other a GX-60 by Apollo (UPS). Anybody got an idea how to fix this? I have tried grounding and shielding all the PC lines, etc to no avail.
