[Elecraft] K3 Drive Levels and the SPE 1.3K-FA

[Keith Trinity WE6R]

You can play with the Config Menu watt meter calibration high and low 
numbers to get the switch-over point different.
IE where the Low power amp (LPA) switches to 100 amp (KPA3). This 
happens at 12W "indicated".
The two Calibration numbers are for all bands!

So; Go into config menu WMTR LP (below 12W) or HP (above 12W). (note 6 
meters switches at 8W)!
Make a note of both numbers so you can put them back!
Extreme numbers to get the KPA3 to click in at lower actual power levels 
would be to set both for 180 (max).
You will have to use an external watt-meter to see what is going on as 
the K3 internal watt-meter readout is all out of calibration now!!
I just played with a radio and it switches over at about 7 watts with 
both numbers at 180
Have fun!
