[Elecraft] k3 High Current Message on 10 meters

[Don Wilhelm]

Harv,

I think the key is what you said about "long cycles modes like RTTY".  
Things heat up in those instances and the current will increase.  The 
only 'cure' is to reduce power.  I would suggest running RTTY at a power 
level of 50% of the CW/SSB rating for the transmitter.
