[Icom] Power meter on my 706 MKII

This isn't unusual....  The meter can't keep up with the peaks on SSB.
Turn on the Compressor and you'll see a difference because the average
output increases.

My 706MKII exibits the same behavior as yours.

Subject: [Icom] Power meter on my 706 MKII

Hello Icomites,

I have a MKII that I use as a base. While making some measurements a few
days ago, I realised that the power meter on my MKII was way off on SSB
compared to what is registered on my Diamond SX 200 power/SWR meter.
Everything else works fine..its just the power meter. SWR indicator is
close to what is registered on the SX200.

When I key down on RTTY and CW, both mode registers
close to 100W. I go on SSB, the meter on the radio
indicates full power while, the actual power output as
seen on my SX200 is only 50W. There is no RF loss as
the SX 200 is in line with the radio and the antenna
tuner. The SX 200 is connected to the radio with a
short stretch of coax (about 30cm). Has someone
noticed this on their radios? Is there anyway we can
calibrate the meter? 

When I had my station inspection done a few days ago,
the inspector mentioned that he had observed this with
most radios. I doubt his statement as there is no
point in having a 'way off meter' on a radio when it
does not serve its purpose. Just my thoughts

In anticipation for your inputs
