[Elecraft] Portable Power Supply

[Geoffrey Mackenzie-Kennedy]

I used a Toshiba laptop computer power supply to power my K2 (receive only) 
for almost 3 years nonstop 24/7 during a propagation study, although I did 
add a voltage regulator placed betweeen the supply's output and the K2. This 
particular supply is rated to deliver up to 6 amps at 15V, but its output 
voltage is not well regulated and will increase as current draw decreases. 
The supply generates noise at HF which could be a problem when operating 
portable.

Footnote. Should anyone contemplate using a Laptop's supply in cotinuous 
unattended duty, I suggest that the supply should be enclosed in a fireproof 
box as a safety measure.

73,
