Galaxy dx2547 (959) No squelch

[CbRadiosPRONTO]

cannot engage squelch (constant static). Squelch pot is adjusting correctly 0-50k. The problem is on both AM and SSB, however I check Vr3/d15 and vr4/d35 anyway, and they're good.

Should I be looking at IC1 or possibly a transistor? I don't have a voltage chart.

Suggestions?

Here ya go

IC1 checks out, including pin 8, which adjusts in voltage as squelch pot is increased.

Suggestions?

Maybe the squelch isn't the problem; check feed signal to the squelch?

I handle general radio work whereas my vacationing tech normally handles the tech stuff.

Not a tech either; but it seems like a logical guess.

Thanks, Robb. I traced it back to Q44. The trace was pulled away from the board, slightly. Re flowing the solder did not fix it though. Q44 was actually bad. It must have gone bad from having the bad connection.

She's back in business.

PS: This is a fresh out of the box radio. Arg. Happens too often.
