[Elecraft] K2 Alignment and Testing Part 1 Troubles

[Ken K3IU]

G'morning Curt:

Sorry I can't help you with your specific problem, but PLEASE don't 
think that this list is "mainly for K3 owners." It may look like it at 
times, but this list was here long before the K3 was even announced and 
is open to any and all issues related to any Elecraft product. It is 
certainly appropriate to pose your K2 related query here.

Hope that the new MCU fixes your problem.

73,
Ken K3IU
