Hi Terry,
Well, the small NiCd battery pack on my DJ-580 has a nominal 7.2 volt rating (when years ago it would hold a charge, that is), so a 9v supply should be plenty for proper operation. You won't get the full 5 watts out, but receive audio should be unaffected.
Perhaps the audio connectors might be dirty? Also, recall that there is a difference between the V.U.SP jack on the left, and the SP jack in the middle, with a stereo plug required for the V.U.SP jack. Which are you using? Volume control still work (no dirty wiper contacts)?
I've not used the radio for some years now, though it does still power up with external power... Might be worth dusting off, since it is full duplex.

Hi Folks,
I’m trying to resurrect my old Alinco DJ-580 for use on AO-85/91. When using the DC supply socket on the side with a 9 V plug pack, I’m finding that the Rx audio output is very low (the nicad pack has at least 1 dead cell).
Is anyone still using one of these radios and if so how well does it perform?
