Hi Vic -- I am far from expert on this, but I wonder if you can locate ANOTHER protective diode in the receiver circuit. I once killed my Omni VII receiver by hot-switching an "active" receive only antenna - the power connector arced to case ground of a bias-tee injector as I plugged it in, and that fritzed the receiver. Gary at TenTec service called me to explain it before he fixed it, and I believe he said there were multiple diodes to protect the rig in such cases.

So... perhaps you have more than one diode or fuse or other prophylactic device to check?

I lifted the component (EMI protection diode?) that jumpers the coax
connector on the back of the Paragon, but it made no difference.
