Cobra 29 NW LTD

Hooked up 29 NW ( stock power no P&T) when I keyed up mic needle moved to 9 on meter ( normal) when I unkeyed the meter moved back to 7 and stayed there and antenna warning light came on, and then key mic again, unkey, and needle went all the way back to the left. Any ideas whats causing this, is not the antenna because tried three other radios and they function normally.

 

Yes, was using a Ranger SRA 198 which has always worked well with that radio, so I tried Astatic 636 and RK 56 and they both did the same thing.

 

I have a Huster Q27 antenna installed on a bird perch on a 2015 volvo, swr is 1.2, and as I stated, my other radios didnt exhibit the same problem. I got to believe its something in the radio, I was just hoping to get some ideas before I take it to a Cb shop. Guess next time Im in San Antonio I will go to Clays, I trust them.

 

I didnt try talking because when I first keyed up the ant warning light came on ( and it usually doesnt) so I unkeyed and that is when I noticed that needle just went back to 7 and stayed there. I didnt hear anyone on receive but did hear normal white noise.

 

Update: put radio back in line and it works fine, dont know what was causing it to malfunction, maybe coax to radio was loose, dont know but its working now. Thanks all for your input.
