[Elecraft] K144XV on digital modes - disappearing power

[Don Wilhelm]

Kjeld,

Are you driving the audio up to 4 bars on the ALC meter with the 5th bar 
flashing?  This is the "zero ALC" point for the K3, KX3 and KX2 
transceivers.

Without sufficient audio  The K3 will "power hunt", and that may be what 
is happening.

Refer to the article on my website www.w3fpr.com.  Scroll the left 
column down to the lat article and click on that link.
