If you're still getting loud squelch noise but do not receive on any channel, you must check the RF from the antenna to the audio stage(not included). There must be more than just one RF stage in this radio. Let me know what you find.
Hi What I do with a perfectly healthy radio is to run around the house with it until it recieves properly. I may have to use the old advice from 60years ago to fasten the antenna to a radiator made of iron(if they are still to be found). Then you are sure to get the radio working. If all goes to the worst you may have to old the radio above your head. (take care to use one hand at the time, this was done in my youth- 60 years ago) hope this works for you Kolbrun
Sounds like an internal prob within the reciever, since recievers have radio tuners in em, maybe a prob in the input switching in it.
I assume you are running unbalanced rca cables out of the dvd player into the reciever as it probably doesn't have balanced input capability, unbalanced lines are susceptible to R.F.I. ( radio frequency interference ) but I doubt if that's the problem here unless maybe you are running very long cable lengths from the dvd player to the reciever.
Try using a different input and see if the problems still there, can use any input other than phonograph really as they are all line level inputs.
IN your CB there are 25 tuneing slugs (square matal cans with
ferrite tuneing slugs) if you speaker output is low leavel but still
clear and free of hash the set should be ok , but you will need to tune these slugs with a small jewlers screw driver (WITH GREAT CARE) as the slugs break easy. If you want to email me it will not be a problem ,cheers , DENNIS [email protected]
Mounted on the circuit board is a tiny black encased rx/tx
changeover relay. It is almost in the center of the board and one third to the left (facing the controls) and may be etched MRATA.
I would be looking at that. These sets are subject to a lot of problems as they age and can be fixed with a BIG HAMMER!!
Have you checked that both radios are in the same Channel and the same Squelch Code? are the batteries ok? any rust in the battery contacts?
Some FRS radios gets a Malfuntion, and the syntom is like that, check this first
