[Elecraft] use of the KX2 charger as the PSU

[Matt Zilmer]

Hi Howard,

The Tenergy charger isn't an AC adapter.  It is designed specifically to 
charge the Tenergy pack used with the KX2.  As a charger, its output 
runs constant current initially, then it switches to a constant voltage 
for the final charge push.  This type of charger should NOT be used with 
a KX2 because of the constant current output.

The best type of mains-powered for the KX2 to use is an AC adapter, 
rated 3A or higher.  I found that Triad makes a good set of them, and 
they're available at retailers like Digikey and Mouser.  Others on this 
list have also tested various adapters for RFI, etc. (and DC power 
quality) and you might check the archives for that info.

73!
