[Elecraft] K3 Low Output on 15

[W0MU Mike Fatchett]

Did you do a re-calibration?  Is this output confirmed on a external 
meter?  Do the K3 and external meters agree is what I am asking.

Is there some way you are getting rf back into the rig just in 15m?

Does it do this on a dummy load?

Have you taken the K3 completely out of line, no computer, no amp, no 
tuners etc?
