Same with me, currently just try to find out why the
AF MONI sound is more loud than the retransmit AF out.
I tried to adjust VR4001 but it doesn't much help.
And your comment give me some ideas.
At schematic diagram and in service manual book, they
mentioned about -20db AF attenuate by R4180 and R4211
before limiter op-amp.
And my idea is to bypass or to change with VR so later
I can adjust the AF attenuation
If it is not solve the problem, I will try to look at
electronic volume control Q4029. The IC is controlled
by maxdev trough DAC.
This IC fungtion is for control volume AF out before
TX MIX op-amp. maybe change value C4162 and C4171 to
4.7uf will also help.
