When I drag the tuning, the parallel input port on the radio<br>causes noise in the audio and spectrum. It does this even when the radio is<br>off. Everything is grounded well and I tried an entirely different<br>computer and parallel cable. I tried grounding different points with the radio off. I found that grounding the 5volt line near the connector helped some. I bypassed the 5 volt line at that point, but that did not cure the problem. This noise also causes the XVTR Tx relay to clatter when that option is checked on the XVTR screen. HELP! Paul WA3GFZSun, 06 Jan 2008 12:24:58 GMTwa3gfz
