Galaxy DX2527 Low Volume Help?

[dx77HML]

I have a Galaxy DX2527 and it has very low volume.Receive is normal and transmit is normal.When I first turn it on after it has been off or unplugged for a while it makes a whine noise like a scud missle coming in then quits.Volume wide open and barely able to hear.No audio can be heard when operating in PA mode.I have low volume in all modes.This 2527 was made in 1998 according to the serial #.Have checked the audio IC and several caps and diodes in audio circuit.Transmit on AM,SSB is fine.Anybody have this problem with a 2527 or have any suggestions??
Thank's!

Found the problem finally.C-219 in front of the audio IC was the culprit.Replaced and all operations resumed to normal!

Great! I'm afraid I wouldn't have been any help in determining your problem... a tech I'm definitely not.

By your user name, I assume you either have or have had a DX77HML. I've had one in the mobile for many years (since 2003??). It's a good rig, and drives my MagnaForce 350 very nicely.

The only beef I have with it is that its receive is w-i-d-e on SSB. Do you know of any mods that would narrow it down a bit? Say to 2.8 kHz or thereabouts? That would probably mess up the AM/FM receive, though.

Maybe one of those DSP speakers would be a good option... ?

Have you thought about the Schottky Diode mod to clean up the receive on that Galaxy 77?

I wasn't even aware of any mod to clean up its receive. I'll check into it. Thanks!
