[RTTY] Rig Control Problem

[John Grimm]

I recently went from serial port to USB operation and am having one problem with the new setup, which is 756Pro3, Writelog10.76, Microham Microkeyer, Win7Pro 64 bit.  After I send *some* exchanges, the radio frequency and/or mode as shown on Writelog goes momentarily crazy and can indicate pretty much anything.  It then usually resets itself correctly after a second or so and the rig stays put and never reacts to what is shown.  If I hit enter and record that qso during the exchange, it gets plugged with a big red B or the frequency/mode is recorded incorrectly.  This happens fairly often and randomly, regardless of band, and will occur even with no rf applied.  I have lots of ferrite on all cables, the baud rates are all set correctly on rig/software, I've tried 19200 and 9600, and tried on 2 computers.  Still the same.  Any ideas or feedback sure would be greatly appreciated.  John / K0YQ
