[RFI] CO2 detectors and RFI

[David C. Hallam]

If you want to read about how poisonous co2 is, look up the story about 
the African Lake Nyos disaster in 1989 in Cameroon.

While transmitting on 80 meters after a while it starts audible warning, very loud.  I called the company tech support line and they did not have any solution.  As an experiment I plugged the detector into a two wire extension cord and wrapped the extension around a #31 mix snap-on, then tested and it did not go off.  The tech support said not to use an extension cable with the detector.
