[ICOM] IC-756ProIII: Meter adjustment menu Was: increase tuning power to 20 Watts?

[Alex]

I've done that before with the FT-897, but didn't want to go that route 
with the P3. I want one button convenience when using the external 
tuner. :) I'm using the P3 with a MFJ-993B and I found that the 993B, or 
perhaps just the unit I have, doesn't measure the reflected power very 
well at 8-10 Watts. Every time the tuner found a match, I noticed that 
the SWR was a lot worse with just a few extra Watts applied. So for 
instance it finds a 1.0 match at 8 Watts, but when you transmit a 20 
Watt carrier, the SWR it then calculates is 1.6. Now I adjusted power 
used for external tuners on the P3 to 20 Watts and things are a lot 
better so far. The tuner is rated for 20 Watts in tuning mode (or 100 
Watts if the rig has a foldback feature). Still got some more testing to 
do.

Incidentally, it looks as if the P3 relies on the foldback feature when 
the internal tuner is used.
