Unfortunately I have not found a way to increase the weight of the Winkeyer
when it is under control of the N1MM Logging Program. I can change weight
with the Winkey Utility Program, and the K3 CW sounds fine, but when I exit
the utility, the weight setting is not sticky. I don't see any weight
setting in N1MM.

Increase the weight setting going into the K3 jack.
73, Roy K6XK
harp-eared operator at W3LPL told me that my CW keying sounded a little
light in the CQWW contest. I am using a Winkeyer, controlled by N1MM
Logger, connected to the KEY jack on the back of the K3.
An oscilloscope shows that the Winkeyer is producing a string of dits at
the proper 50% duty cycle. However, looking at the RF envelope of the K3
output, the duty cycle is about 40%. Listening to the K3 on another
receiver, the dit shortening is quite noticeable. If I set CONFIG: CW QRQ
= ON, the transmitted dits are exactly 50% duty cycle. However I can’t
live with the RIT, Split, etc. restrictions with QRQ ON.
I have two K3’s, and they both behave the same way. Any ideas out there?
