Just a heads up.
I purchased a Kidde NightHawk CO2 detector model KN-COP-DP-LS, it is designed
to plug into a wall outlet plus it has a 9 v. battery backup and LED readout.
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.
So if you are looking for a CO2 detector be aware of this problem with 80 meter
RFI tripping the detector. I went to strictly battery powered CO2 detector and
that works fine.
