[CQ-Contest] Kenwood ts-850sat RFI issues

[Bob AD5VJ]

Wanted everyone to know:

 I finally resolved the RFI issue with the TS-850sat and Drake L-7 setup.

 I had to end up regrounding everything and then the computer to the same
ground as all the other equipment. 

After a generous ferrite treatment which resolved nothing but the
interference to my keyboard, the computer grounding gave me a final solution
and am active again on cw at full power out along with rtty and psk, etc.

Still don't understand why I had no trouble with all the other rigs I had in
here before the Kenwood 850. I had everything from Icom 756 orig to a Yaesu
FT-1000MP MKV and even a Kenwood TS-2000. 

Maybe it works better HIHI

Oh well all's well that ends well.

Thanks to everyone for the help
