[R-390] Computer RFI and R390s

Mike,

A couple of things . . .

A) you must get the antenna to a low noise area, away from the house.  The rx
should be fed with good quality coax all the way to the ant.  The ant does not
necessarily have to start at the house.  You can bury the coax and start the
ant somewhere out in the yard.

2) you should choke off all of the transmitters, that is, all of the cables
coming off your computer with iron toroids or equiv.

But the main thing is it is coming in the antenna and your ant is in a high
noise area.

This may not elim the noise but should help.
