Radio Make and Model: Cobra 2000 GTL
PCB Number: pc-497aa
PLL Number: 8719
Test gear available: Motorolla Service monitor R-2200b, Freq Conter, Digital and Analog VOM, Ect...
Symptoms: I am having trouble alligning the sideband on this radio. I can get the tx to line up perfectly but as soon as i go to set up rx the fun starts. If i can even get the rx to line up it throws the tx off again. Something is wrong in the sideband section maybe there is someting sorted that is causing the two frequencies to mix? any help would be appreciated.

thanks,

Mike

I am having a similar problem with my 148gtl-can you tell me how you are lining up the transmit and recieve,in other words wich cans for the receive and wich ones for the transmit etc...

Hmmm...this looks nearly same like President Madison

You got a solution? What? I have the same problem, will be the PLL?, bought a new switch but when the radio did not have audio.
