Recently purchased a used (but in excellent condition) FT-1000 MK 5
with MD-200.

I am having trouble setting up the microphone, and am told my TX audio
is FLAT.

What are the best settings with this mic and radio, ie:-

What menu settings should be changed and to what value?

Where should the PROC knob be turned to, and also the MIC knob?

On the bottom the the mic is a switch, which way should it be set?
Also inside the mic is a rotatable control - again, how should this be
set?

Thanks for your help in advance.

Best Wishes...
