My ready-to-plug grounding (mass) solution
Very strange... (not your idea, but ATM I don't have an explanation why this helps).
BTW: Could you check the voltage between the CF-adapter ground pins (on the power connector) and the Atari RF ground (without your cable)? If it's something else than 0.0xV, you most certainly have a bad connection somewhere.
so long,
