I use jumpers from my IC756 to my Ameritron AL800 amp. Occassionally, I
notice that certain bands, mostly the low bands, become effected with signal
attentuation coming into the rig. The coax checks ok with a meter, but what
might happening to it over time to cause this...I change out the coax, and
the newer coax cures the problem- but the old coax seems to look ok......any
suggestions or ideas??
When I do end up changing out the coax jumper, sometimes, I have to go
through 2 or 3 different lengths to get one that works- I've had 3 footers up
to 20 feet.......all RG8X......I just chalk it up to the DX gods but what
might be happening here and any suggestions on curing the problem-??? Of
note, I did have a piece once that work just fine except on 12 meters, when I
changed it out, everything was good again until after about a year-
