[Elecraft] K-3

[Don Wilhelm]

Gerald,

Have you checked the power cable?  Are the connector blades of the APP 
connector fully inserted and locked over the locking blades in the housing?
Are the connections to the power supply tight?

Too much resistance in the power cabling (due to loose connections) can 
cause exactly what you are observing.
