[Elecraft] K3 Current Drain When Off

[Josh Fiden]

Hi Jim,

A couple of thoughts.... I have a Kill A Watt meter for measuring line 
power consumption and discovered it is VERY inaccurate at the low end of 
its range. I was measuring an unloaded DC linear supply and at values of 
a few mA it was high by a factor of 10 (!) compared to a Fluke 87V. I 
haven't used the Watts Up meter, but you might want to check its 
accuracy in this range. Also, if the K3 is dissipating 4-5W when powered 
off, I'd expect that to be a noticeable amount of heat.

73,
Josh W6XU
