[Elecraft] OT: wall wart for RX-only PS?

[Ron D'Eau Claire]

Check the actual voltage, Doug. Often a "wall wart" has very poor
regulation, with the voltage of a "12V" unit jumping to 15 or 16 volts under
light load and sagging to 9 or 10 under full load. 

Also, their filtering often leaves a lot to be desired. Some have none at
all, producing pulsating, unfiltered DC and depending upon filtering in the
device being powered. 

If neither of those points is an issue, it should work for receiving at
least.

OK folks, I do own a pair of K3 and a K2...but I also own A Yaesu
FT817.  Here is my question....

I want to set this up away from the shack, but still in the house, for
RX only (when I'm not in the shack).  I have a RS wall wart rated at
14 watts (12v, 500ma).  Is there any reason why I should NOT use this
as the PS?

Thanks,
de Doug KR2Q
