Thanks me to . I know there is mixed feelings about Dustin and his work but I must say speaking for myself my comp 29 is a animal barefoot when I run my amps that thing is a monster.
 
It might be a good idea before you "lock and load" on the connections...

Check for that looseness and even clearance - make sure the knurl seats and the feruule under it is not loose...

Give then a good tug to see if the "knurl - notch and Teeth" are seating and you can't twist the coax sheath (not the knurl twist on - it's ferrule the one on the PL-259 that slides into the connection that has both the center pin and outer shield) make sure you can't make it move or make it shift.
  • - if that's the case, you're going to need to make some changes to the SO-239 PL-259 connectors
  • - that may require retightening or rework/redo the SO-239 at that component of your system so you can provide clearance to the PL-259's screw "depth" - if it's too long - replace with a different brand of PL-259 or even to the extreme of grinding off / filing down that knurl ring to threaded portion - but it looks like hell - so better to replace with a less deep connector - even if it means using a different patch cord
I've seen a few PL-259's that their outer Knurl thread-depth is TOO deep in depth, preventing the notch of the PL-259 and teeth of the SO-239 - not mating making a SOLID sealed - SEATED connection - it will come loose if you fail to check it on occasion.

Don't want to see you lose your monster to a bad connection...

Mostly wear and abuse. It also happens when someone leaves a solder blob on a coax connector and jams it in the socket.

I replaced a relay in my amp because of this recently. Intermittent RX loss was the symptoms. I could key the amp a couple of times with the foot pedal and the RX would come back. I figured it had to be the relay but I was wrong. The connector under my work bench that goes out to the antenna was loose on the center conductor.

Hopefully it fixes your problem.
I have a radio that does this, I'm going to have to take a closer look. Thanks
 
UPDATE. My 15 year old jumper died. I tried 2 new truck stop junkers both bad . Moral of the story don’t go cheap . Dustin fixed me up with new jumper solder amphenol ends with big grey chord. I’m 10-8 again.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
  • @ AudioShockwav:
    Wes, it's better if you start a thread on the main forum, more people are going to see your question.
  • @ heartbreaker3473:
    Okay, sorry, will put in a forum
  • @ heartbreaker3473:
