I have the filter dip; it was not cured with realigning, but realigning was
anyway helpful to gain a dB or two.
I also see that disabling AGC cause less noise in FM while listening to 2m
converted to HF by the internal converter of the Yaesu FR-101. I didn't check
if enabling or disabling AGC cause any change in the filter dip, anyway I'll
check and report soon.

It uses a MC1496G as mixer and two CA3053 as IF. Plus some DG FETs, in first
RF amplifier, after the mixer... What information do you need?
