This is a reply that I posted to email on the NCCC list this morning.
The original post complained of buggy control between a Microham
keyer and Writelog. I don't think it's a WriteLog problem.

I'd put my money on pin 1 problems in the keyer. I haven't done
actual testing, but AE6RF used one at my QTH over the weekend, and
it was still here when I returned from N6IJ. After I tore down his
station to make room on my operating desk, I opened up the Microham
and studied its construction. I can't find a single connection
between a cable shield and the chasssis.
