[Elecraft] Possible power supply option for the KX3

[Geoffrey Mackenzie-Kennedy]

Phil,

If of any help to you, I did use a Toshiba Laptop power supply to run my 
K2's receiver continuously (i.e. 24/7) for almost 3 years in Scotland during 
a propagation study.  This supply's output is stated to be 15 V DC, and its 
current rating is 6A.

Because this supply's voltage output is not regulated, thus can increase 
when the current demand decreases, I did add a voltage regulator set for 
13.5V output between the supply and the K2.  I also placed the supply in a 
fireproof box :-)

RF noise from this supply was not evident on the K2.  However the antennas 
used during this project were a good 200ft distant from the house, and all 
cables to the antenna "farm" ran underground.

73,

Geoff
