[Elecraft] W2 Resolution

[Jim Miller KG0KP]

IMHO from RTFM = From the Manual on the W2 Copies below, you will see that 
the W2 will range the sensors.  The 2KW sensor for instance can show only 
0-20 watts so with 20 lights, the lowest light lit would be 1 watt.  and for 
the 200 w sensor it will be 1/10 watt.
