throw it away and get a real radio.I have a maxon 45 that I am trying to repair for over three years and Every time I come close ,it not the problem.Radio is to old just save it for parts or junk it but get a new one.
I have one that doesn't transmit between the two we could have one radio but who's.. you should try to tune the receive cans but with no schematic you can't because if you turn the wrong one you could kill the radio. I would buy another radio like a radio shack trc - 503 or something in that line if you're into small radio's. Some of them can be opened up to talk like a big radio.
Could be a few things.One as simple as a bad soilder on the board or your voltage regulator could have went out. If you take the top cover off and talk in the mic and its starts transmitting then you have a bad soilder to check the regulator is a little harder and not for just anyone to do.
You said that you can hear everybody and then you said all you can hear is static. Which is it?
If you can hear everybody and you have switched to a known good mike, then you either have a bad antenna or you have a bad final amplifier caused by a bad antenna or by having transmitted at sometime without an antenna at all.
sounds like you are getting a feedback squeal.. try taking a wire and attaching to you handheld and grounding it to something.. that might work.. i know i have to have my mic on my cb grounded to my radio or i get a feedback squeal...
Check you mic first to see if it is indeed working. Then if it is the below advice is applicable. It sounds as if your TX audio amplifiers might be malfunctioning or the TCXO might be bad. If you have a background in Electronics I would suggest that you open up the unit and using a dummy load on the antenna check the two TX audio amps to see if when you key the mic and speak into it the amplifiers are amplifying your voice and sending it to the modulator. If the problem is not amps or the filters in between the amps, the modulator and the VCO buffer are suspect. If the TCXO is being modulated I would check the PPL IC and the Drive amp to see if the modulated signal is getting through. The last two checks I would perform are on the final amp and the TX switch prior to the antenna jack.
If you do not have a background in electronics, still check your mic, but the rest of the above advice can be done by a qualified Radio Technician.
I recall the combo unit as I used to sell them. I am about sure they are no longer avaidable. You never know, you might see something on ebay/auction sights that might be to your liking. Good Luck.
