Another 2517 low receive issue

[Hawkeye351]

Check for voltage on the RF gain wiper lead (center) with RF gain turned down to halfway.

Also, check R233 for voltage on the rear lead, should be the same as the voltage on wiper (center lead) of the RF gain control. Also, check Q17 and L5.

...and here comes the freezing rain, I gotta go salt sidewalks

oh! I was just outside, walking around, in a T-shirt, drinking a brew.

I just got off the phone with the owner of this radio with the low volume (receive signals are great, just low volume) and he informed me that the squelch control is the same way, he has to crank it almost wide open to silence out even the weak stations. I checked the squelch VR adjustment and it's set properly. So I guess once I figure out the volume low issue then the squelch issue should also straighten out, I hope.

Question:
Isn't the squelch and volume tied into the same circuit somewhere that could be affecting both?

Also, does the transmit audio go through the 7222ap audio IC as well as the receive? If so, then could the IC be bad on the receive audio side but just fine on the xmit audio side?

Stupid questions probably, lol...

No, the transmit audio does not go through the 7222. It looks like it comes off pin 1 of the op amp and goes in by the AM carrier control at Q53.
