[Kenwood] Ts-850 : ALC strange problem

[Allan]

Hi all,

I have a strange problem with my modulation (ts-850sat+mc60), I did some
test :

With 50 watts, compressor at 5 o'clock (10 db ) , mic gain at 3 o'clock (
alc indication is ok ) so my modulation is good.
With 100 watts, compressor at 5 o'clock (10 db ) , mic gain at 3-6 or
maximum o'clock ( alc indication fall down ) , modulation very strong in the
monitoring but on the airs the modulation is bad .

If I use the tuner, and tune the antenna, with 50 or 100 watts the
modulation works fine.

But the swr not matched is good, i have 1.2/1.

Do you have any idea of the problem ?
Which board must I test ?

This problem start when I used my amplifier, maybe any relation ...

I search on internet but don't  find something concerning my problem, find
dc-dc board problem but don't look like the same symptomes.

A big thanks for any help,

Regards

Allan
