    have an old TS-930 that works great but when you key the mic in ptt, even with mic gain to zero, meter pegs. Listening to the audio in another external receiver sounds fine. scope display, audio does not seem over driving, just the radios meter pegs. Is there an adjustment somewhere to tweak the ALC reading on the meter somewhere (have not found it yet in the SM I am perusing thru).

    The listed instructions show them to be on the SIGNAL unit. It requires a calibrated output af generator
