[Elecraft] Firmware, K3, large jump AB3JN

[Keith Trinity WE6R]

You must go into the config menu, set KPA3 to "nor" then cycle power. 
Then connect to the utility and the 50w should be available to run from 
there.
Set KXV3 to nor also, cycle power, then you can use the Utility to run 
the MW test too.
Looks like you DID do the 50 manually and the TXGN number most likely 
changed, (see next sentence). (The MW and 5w need to be run too).
You can do all the gain cals manually but the Utility is soo much 
easier. Manually you make sure TUN PWR is nor, then set power to 50w 
EXACTLY, (or 5w for the low cal), then long press XMIT and let it send a 
carrier for several seconds. You will see the TXGN number change from 
the default 10 to something (although 10 is a valid number too, just the 
default and should not be 10 on all bands). For MW, set KXV3 to "test" 
and set to 1.0mw exactly and TUNE for several seconds) DON'T FORGET TO 
TAKE IT OUT OF TEST, HI HI, there is NO indication and it will confound 
you, been there, ha ha.
Then Never, ever, EVER set your tx power to *exactly* 5watts, 50watts or 
1.0MW ever again because you can inadvertently re-do the tx gain cal and 
if not into a flat dummy load, you can get it all fouled up.
