I really would like to help, but...

Please, please, slow up and try it again. Please use whole sentences and
don't abbreviate. Tell me what YOU are measuring. I can read the manual on
this end.

Jim,
I'm still troubleshooting a squelch problem - I can't easily overcome the
squelch - on my RST-442E and have a query re the Operations and
Maintenance Manual content.
Section C. 3. Troubleshooting Procedures. Audio Microphone Response Tests
(a) and (b) on Page C5 note that the output of U101A pin 1 should be 3.5
volts peak to peak from a 0.5 volts P-P microphone input [speech] but
Section D. Theory of Operation para 1 on Page D1 notes the output at U101A
pin 1 from speech will 1 volt peak to peak.
Which is correct?
Thanks,
Leo
