[RFI] Nighthawk CO2 Detector

[Chuck Gooden - N9QBT]

I am having RFI problems with a Nighthawk CO2 detector when I operate on 40 
Meters.  Does anyone have any Ideas on how to get rid of this problem.

I am planning to try a Ferrite core on the AC Line (hot lead only) inside the 
electical box as soon as I can get some but any other ideas would be welcomed.

The CO2 Dector is Model KN-COPP-3, Assembly #900-0076, Manufactured 17 April 
2000.

Thanks,
