[SEDXC] Low Band RFI

[Tom W8JI]

Your antenna layout and wiring, both of which are unknown, are critical for 
solving problems like this.

Since I've been home, it's been a mad rush before Christmas to get antenna 
work done in the backyard. While everything is almost done, I now have a new 
problem: RFI. While testing on 160 yesterday and tuning the amplifier up on 
80M tonight, I've had some horrendous RFI - to the effect that my home alarm 
system thinks there is a fire in the house whenever I transmit with over 300 
watts on 80 or 160 - VERY NOT GOOD! What really gets me is - when I was home 
for Thanksgiving, I was having no problems running 1000 Watts on CW on 80M - 
somethings up...
Before I call the alarm company, does anyone have any suggestions? >>

The alarm system should not be a radio detector, but problems like this are 
almost always a combination of two  systems being less than perfect or 
ideal. In this case one is the alarm system, the other is likely the antenna 
installation.
