Hi guys. I recently bought a 737 that i had shipped. The seller described the radio as working fine. I just received it yesterday and unboxed it and connected it today. Initial light / quick testing earlier today wirhout yet transmitting (i planned on rtfm) i was very impressed. Tonight i decided to try it out across the bands with the main tuning knob and found that when going through the bands there are segments in each band that go deaf. Its like on/off through the bands at about equal intervals if you know what i mean. I guess i got fawked on this used deal but thought i would ask you guys who maybe know this oldie 737 and what i could or maybe dealing with. Ya, the seller will go with "it must of happened in shipping". I reached out this eve already to him and was told it was insured through the post office. Pretty discouraged at this point but i guess crap happens on used deals. Anything i can check or try would be great.
