Anyone experencing noise in their HF rigs from their Power converters? I have a Progressive Dynamics 80 amp switcher and it does get some noise when it is powered up supplying 12 VDC for the TT and batteries. It is comming in to the rig (IC-718 and IC-706) via the power leads. If I run a Astron PS then no noise at all. I've tried two different units to no avail. They are both noisy. Its not a problem during the daytime when I can be on solar.

I also found some noise from my Honda EU-2000i but I was able to get it to quiet down.
