My 257 magnums audio keeps cutting in and out but my receive is fine

need to put it on an oscillascope and frequency counter and have it aligned. even taking to a shop should be less than $45 to have it fully done.

tengo un magnum 257 y necesito la COMBINACION PARA INSTALARLE UN ROAD DEVIL RD104E.

I wouldn't do this...makes them splatter and sound like hell

sounds like the PA has failed, I would have the radio shop serviced

Notice the black mic plug has the numbers it is solder by numbers. Used rosin core silver solder radio shack sells it.

Hello.I have a similar situation on a Magnum 257 HP operating on SSB (AM and FM works fine). If i Transmit it works fine, but when i release the Mic button (after TX), in the bottom side were the RX level should be, it appear somth like a signal level 3 to 5 (constant and continous), but i can't get any reception at all. Only if i turn the TX power level to MAXand i transmit, then it goes back to reception, but not every time. Somtime after TX i need to push the mic button 2-3 times to make it recive somthing, but this wors only if the power level is over 60-70% an i repeat, only on SSB.Can i get some help with this issue?
