I was wondering if you guys had any insight on this. I just got this radio of Ebay. Its an used Cobra 29 mounted in 2004 Silverado with Little Whip antenna in the center of the roof. Radio was advertised as working and tuned/peaked with talkback. I'm powering the radio from the fuse box and ground is attached to the chassis. Original antenna cable that came with little whip was too short so I'm running the 6 foot extension. Cable is not coiled anywhere and slack is laid out flat. My SWR reading on 1 and 40 is about 1ish/1.25 respectively using build in radio meter (separate meter is in the mail so next week I can tune up the antenna better). Now I'm in suburban NJ driving to NYC and even with all the buildings and limited line of sight I should get a lot of chatter. All I'm getting are unclear occasional transmissions.
