what does it do to a set of phones or ext speaker?
my thought lie with a naff speaker.
even though the beep is ok.
have you a sig gen? or maybe stick a radio from the eaphone socket to two
bear wire and put them across the scanners speaker after disconnecting the
scanners own feed, does it work ok then?
you need to find out if it is the scanner at fault or the speaker as the
dirst step.
if an external audio source works, then time to scope the i/p & o/pof the
audio chip.
should be easy to do.

Thanks Mike,


I tried an amplified source via the earphone. The
Amplifier was a Klipsch 2.1 (200 watts) the audio was barely intelligible.
the background hiss was overbearing
and a beep tone at the same amplified volume level was
well beyond tolerability. I will try your other suggestions
as I do have a tone generator that I could get out of mothballs.

regards,

Allen
