Ok I was lazy and had a piece of RS RG8/U between the duplexer and a 60' run of LMR600.
Was using a MSF5000 UHF and a ARR preamp Cellwave 526 Duplexer and a Diamond F718A antenna. Spent many hours playing with the duplexer tuning and adding filtering in the tx and in front of the preamp. Any time I ran the pwr over 30 watts it killed the RX. There was definetly some problem with the cable checked connectors (N) and they seemed fime. But caused a simalar problem when in line with my Icom 910H. Changed out the jumper to 9913F7 and all the noise went away. Comments Welcome.
