[Icom] re pro output power]

George, realize your comments are relative to the factory hand mike's
insufficiency.  For those of us who are using the front panel mike
connector, can we safely assume the SM20 and/or SM8 desk mikes will drive
the transmitter to full output (assumed to be 100 watts)?

| The gist of Julius' comment on eHam.net re the PRO and PRO II being "setup
| for only 60 watts output on SSB" is that the rigs are adjusted per the
| service manual for 100 watts output key-down CW or RTTY. An audio signal
| generator signal fed into the mic connector will indeed drive the output
to
| 100 watts PEP SSB.
|
| The 60 watts comes in from the service technician's observation that *the
| standard factory-supplied mic* will only drive the PROs to about 60 watts
| SSB output.
|
| Thus, the fact of the matter is that any limitation on power output in SSB
| is a result of the inadequate output of the factory hand mic and not of
any
| problem with the radio or factory alignment and setup.
|
| I operate my PRO exclusively with transmit audio being delivered to the
| ACC1 connector and can readily obtain 100 watts output with a two-tone
| input signal with no visible distortion of the signal at that level. As I
| stated earlier, the usual mic connected to the mic connector will only
show
| analog meter peaks of around 40-60 watts at the most due to meter damping
| and time lag. Actually, that reading is probably obtained only with
| substantial compression and probably a somewhat high Mic Gain setting.

| Thanks, Ken, and the others who have pointed me to Julius' review on eHam
| under PRO II. I'll have a look and see if I can unravel what is meant by
| this 60 watt comment.
