Ahh, So is was the one I was thinking about...


Heres a quick tip - KEEP AMP UNPLUGGED FROM POWER - but Reverse the connections - see if the SWR stays the same - Hook up ANT to XMT and XMT to ANT - the recheck SWR - DO NOT POWER THAT AMP DURING THIS TEST.


This is more of a check of which one -


Set SWR on meter to FWD setting...


IF the SWR FWD is the same, then the coax may have been damaged so you simply need to replace jumpers.


IF SWR changes - then more than likely the relay may be more at fault than the coax. Burnt contacts.


The aspects of distance to the connectors is what I'm looking for - if one of the coax jumpers is bad, it's position in the line will affect the FWD reading - not necessarily the overall SWR - it can still be the same - but the ASPECT of the impedance bump affects the CLAIBRATION "FWD" setting too...(Because the coax and the antenna  AFTER then look as a complex load affecting the impedance bump like a coaxial balun)


Just some thoughts...
