[Elecraft] K3 Util "not responding"

[Don Wilhelm]

Larry,

The cable only needs to contain pins 2, 3 and 5 (TXD, RXD and Signal 
Ground).  They should be wired straight through (nor crossover).

Everything on K3 Utility is greyed out because the communications with 
the K3 is not complete.

73,
Don W3FPR
