[Elecraft] K3 current draw

[Keith Trinity WE6R]

Hi David;
You can tap DISP and rotate VFO B knob to see the current. Then set "tun 
pwr" to nor, select desired power out, and long press XMIT to send a 
carrier and see the current.
(do not TX at exactly 5 or 50w as that will cause a TX gain calibration).
That will give you a close reading.
The RX current depends a lot on if you have a sub receiver or 2m module 
but you can watch RX current and change options to see the changes.
If you design a system for 2Amps on RX and 25a on TX, that would give 
you plenty of overhead.
