[Elecraft] Dirty signals was: K3 and Mutek Transverter combo?

[Ray Sills]

This past weekend during the VHF contest, I heard several signals from  
CW operators that were -far- from T9 in quality.  I suspect that they  
were using computer generated CW.. i.e. keyed tones generated by  
software, and using a digital interface to send them.   Problem was,  
to my ear, there was a lot of "buzz" modulating the CW tone.  It could  
have been due to RFI, or just bad audio connections, permitting a  
pickup of AC fields from the nearby gear.  I'm sure they would have  
benefited from reading Jim's treatise on RFI.

My gear was running from battery DC, so I know it was nothing from my  
end.  And, there were signals that were clean.  There were quite a few  
CW stations operating, at least on six meters in this neck of the  
woods... EPA.

Anyway, I had fun operating during the contest.
