I have an icom M700 with an AT-120 antenna tuner.
I understand the importance of good grounding for the AT-120, but do I
need to be as paranoid about grounding the M700 itself ?

Thanks


Steve, here is a good description of the best way to achieve galvanic
isolation of RF ground. The transmitter may use coupling to achieve RF
ground, but if that turns out to harm performance there are options as
discussed in this report:
