Tom,

I know there has been a lot of talk about  the RFI problems you and Junior 
have been having recently.  This may not be practical for  75 or 80 meters, 
where you both seemed to have problems, but  may be worth a try for 17.

Cut a quarter wave counterpoise for 17 meters (about 12 feet, 11 inches) and 
attach it to the ground lug on the amp.   Use insulated wire and tape the 
far end, since it will be RF hot.   14, 16,  18 gauge, or whatever you have. 
Lay it around the perimeter of the room, and if it works, tuck it under the 
carpet or under the baseboard or whatever.

May not work, or may even make things worse, but it's a 5 minute,  no cost 
project that just may help.

Also, just curious:  I know you don't have a real ground system, but do you 
have the rig, tuner, and amp grounded together, or to a common point, or  no 
connections other than the coax between the gear?  Also wonder if you have 
the same RF problems while transmitting high power into a dummy load?


BTW, I did work a few Europeans on 40 last night, but the  band was jammed 
and deafening.  Hope to get on the higher bands sometime today.  Have fun.

73, Steve KW3A
