[Yaesu] Yaesu FC-102 Tuner "Peak" Function Problem

[Ken, WA2LBI]

Good afternoon to the list,

I have a FC-102 tuner that reads about 1/2 the proper output power when in the
"Peak" mode. In the "RMS" mode it reads correctly. I am using a CW carrier as
the test signal.

The manual provides a schematic but no voltage or other troubleshooting
information. Has anybody worked on the peak hold unit, PB-2381? Can anybody
provide any assistance or suggestions?

Thanks,

Ken, WA2LBI
