[Elecraft] Harmonics on AMTOR FEC problem

[Jack Shrawder]

Trying digital modes using Elecraft K2/100 with Kantronics KAM XL and 
Mac G4 running RDCP+Mac software. I started getting reports from the 40 
mtr net that I check into that my AMTOR FEC signal was sold copy but 
described as having harmonics or RFI.

I have been setting K2 on RTTY rather than LSB or USB mode when on 
AMTOR or PSK-31. I reset SSBA to 1 and SSBC to 1 before going on a 
digital mode. Have made a reduction in xmit level of KAM XL from 
default 40 to 35 but no difference.  Set K2/100 power to 35 watts. Odd 
thing is that first couple of times I checked in to this net my signal 
was clean.  So something changed if anyone could give me a idea of 
cause or any corrective action I might take, I'd appreciate it very 
much.

Thanks for any suggestions and 73, Jack
