[Elecraft] K3 Current Drain When Off

[Bill Frantz]

With my old Fluke 97 in series with the PowerPole input to my 
K3/10 (#6299), I saw 0 as the parasitic current. I couldn't even 
measure anything on the microamp scale.

When I turned the K3 and P3/SVGA on, the current readings were 
much higher on the meter than on the K3 internal meter. (On the 
order of 1.8A vs 0.75A.) Turning the P3 off with the front panel 
switch reduced the difference to something on the order of 200 
milliamps. It sounds like most of the parasitic current is being 
drawn by the 100 watt option (or the internal turner).

FWIW, my K3 has the 2M internal transverter and a bunch of 
crystal filters as the only significant internal options. (My 
XYL, KI6SLX, is giving me the 100 watt internal amp this Christmas.)

Cheers - Bill, AE6JV
