[Elecraft] K3S Chirp?

[Doug Smith]

I was in the CW SS in November using my then new K3S with an ACOM 1500.  All of which was *great*.  

But, then, I received an Official Observer Advisory Notice that I was “emitting a CW signal with a chirp”.  The report detailed a QSO that is, indeed, in my SS log.  I was running on 20 meters at the time.

FYI, the ACOM is on it’s own 240 VAC circuit and the K3S is on it’s own 120 VAC circuit.  The rest of the shack is on a separate 120 VAC circuit.

Since receiving the report I’ve listened to my signal on two different receivers and I do not hear a chirp.  Is there any possible way I could have somehow misadjusted the K3S during the contest that would result in a chirp?
