    Well apparently I transmitted into my rf concept 2-317 2 meter amp with a bad coax. I THOUGHT THEY HAD A HIGH SWR PROTECTION CURCUIT. The amp completely nulls all signal and the preamp does not work if i take the amp out of line the rx in my 2 meter comes back. I opened the amp and what i found is when I put a lead from my test meter on the antenna port so-239 of the amp it is shorted to ground. If I put a jumper wire from the cent of the in and the center of the out on the so239 my rx works somewhat but still down about 10db. Any body else had this problem before and what to check
