Re: K1 power out vs current draw.

Mike Morrow-3
The following is not the detail and the variable parameters that
were requested, but FWIW:

My K1 (with LCD backlight, KNB1, KAT1, KFL1-4) on 10.12 MHz
using a 12.6-volt DC supply consumes

On RECEIVE
Low AF volume out     60 mA
High AF volume out   120 mA
             
On TRANSMIT to 50-ohm dummy load  
0.1 W (min)          280 mA
1.0 W                450 mA
2.0 W                550 mA
3.0 W                650 mA
4.0 W                750 mA
5.0 W                850 mA
7.0 W (max)         1200 mA

The best efficiency seems to be around the 5 W output setting.
