I recently purchased a Taiwan made cobra 148 gtl.From a member here that sold it to me for shipping cost, which I really appreciate. It apparently had been hooked up backwards at some point in its life.The hash chokes were burned up, and the protection diode blown. I got that fixed, and changed a 4.7 uf electrolytic cap that was corroded by the brown glue. Then fired it up and cautiously have done some testing on it.
The radio has full output power on ssb, with excellent sounding audio,it is even on frequency. The radio does have receive,but the green receive led is not light,,,but it does change to red on tx. The radio does not apear to have any mods that I can see, channel, clarifier etc even the limiters appear intact. The only thing wrong with it is there is no carrier on am, no modulation no nothing. The the light does turn red, but I get nothing on am. I do plan on doing a full recap just have not had time yet. What can cuase this on a 148 gtl? Any advice is very much appreciated I will not give up on this radio lol.
It will never end up in the scrap pile.
Thank you
