Gotya, Steve.

My main problem is an interesting one.  For some reason, I have started 
tripping off a carbon monoxide detector on the bottom floor of the house 
when I key up in CW, even with less than 100 watts on 40 meters with my DXCC 
which is resonant with a 1.1 to1 SWR on the lower part of the band. 
Actually, I think it may be the detector, because it is of the cheap Walmart 
variety, but I want to eliminate all other possibilities before tossing the 
thing out and replacing it with a better one.
