[ICOM] Clear Speech Speaker vs. MKIIG

[D C Macdonald]

Doug, have you put a calibrated signal generator
into/onto your 706 to see how the S-meter
calibration compares with the other rigs?  You
may not actually have more noise, just a meter
that reads much higher on  ANY  signal!

Gary,

You misunderstood.  The noise is not being GENERATED by the radio. It's the
radio's noise floor that's the problem.  The radio is picking up ambient
noise, noise that most other radios don't hear.  I've substituted an IC-735
and a Yaesu FT-100D and neither radio picks up the noise that the MKIIG
does.  For example, with the 735 in place in the mobile, the ambient noise
with the vehicle running is slightly above one S-unit.  With the 706MKIIG in
place, same conditions, same connections, the noise is a solid S-7.  Similar
results with the FT-100D, slightly over one S-unit.
