[UK-CONTEST] N1MM glitch

[Darrell G0HVQ]

Hi

Not familiar with the MicroHam keyer but I used N1MM on CW via a USB/serial 
port converter and a homebrew interface (lots of ccts on the www) to an 
IC7400 and don't get the symptoms you describe.

Clutching at straws, but can I suggest opening up the keyer and/or 
monitoring the USB line with a multimeter to determine if it's the 
software/PC keying up the interface (and hence the radio), or something in 
the interface keying the radio on it's own? Or borrowing another interface 
from someone near you? Or knocking up a quick interface, should only need a 
few components.

I only started using N1MM in the past year but am a complete convert, 
although this IOTA was the first time I'd used the CW facility.
