[Ham-Mac] RFI getting into computer

[Dick Kriss]

Dick,

Too bad you cannot put the bookshelf antenna in another room.  Too bad you
do not have an attic for the antenna.  Any distance you can get over the
current 10 feet will help.

I cannot comment on how RF will effect the new Mac.  If it does not bother
the Toshiba laptop, you may be okay.

Good luck.... if the window box antenna will tune six meters, try 50.290 for
PSK or HELL.  The band was open over the weekend.
