[Elecraft] Lo P error on K2

[Don Wilhelm]

Bob,

It is difficult to tell you where to look.  That message indicates that 
there is less than 2 watts being produced.
If you have the power control set to less than 2 watts, that message can 
be expected, just turn the power knob up for a 'cure'.

OTOH, it could be the result of damaged wattmeter diodes in the KAT2.  
Give the wattmeter a check - Set the ATU menu to CALP and connect an 
external wattmeter between the KAT2 and a dummy load.
Set the power to 5 watts and do a TUNE - what does the external 
wattmeter read as compared with the K2 display.  If the external 
wattmeter reads 12 watts or greater while the K2 indicates less than 5 
watts, then something in the KAT2 wattmeter has been damaged - the 
diodes are the most likely suspects.

73,
