Hello everyone. I have a Older Uniden PC76xl, Philippine made and it is hooked up to my 102" ss whip. 1:01 swr on channel 1 and 1:2 on channel 40 so, no swr problem. Using lmr-240uf coax cable around 15 ft.
The problem I am having is when I key up and talk on say channel 1 or 2, and up through the channel 11 and 12 freqs, the needle actually swings backwards when modulating.
When talking say from 12-13 on up to channel 40 then the needle swings forward.
It's like it's not modulating correctly on the lower 11 meter band but, is on the upper end of the band.
It seems to talk well but the backward modulation on the lower channels has me puzzled.
Anyone know what might be causing this?
