Here is what I ended up doing. Bear in mind that I live in a small farming 
community in SE MB and do not have ready access to bits and pieces that many 
hams take for granted and make do with what is available in the shack, the local 
hardware store and a Radio Shack agency. Components used include 12" of two 
conductor #26, two AA cells and some black electrical tape. The two AA's make a 
3v battery - no holder, that's what the tape is for. The wire connects the 
battery to the enhancement board via a hole drilled in the rear panel of the 
Kam. The wires are soldered to the now defunct button battery holder. Having the 
taped up AA's laying on the desk beside the Kam may not be a pretty sight but it 

As soon as I tweak up the vco's to get rid of the dots on the '440S I'll enable 
my gateway station.

Thanks for all the suggestions.
