I upgraded to the latest version last evening and that went very well.
I operated the CWT contest this afternoon and noticed some strange happenings with N1MM.
I was operating at a transmit speed of 25 WPM.
I didn't have any problems with the receive, but when I transmitted it seemed that there were times when the letters were rolling into one another.
There didn't seem to be the crisp, clear spacing that I had before with Version 1.2.
Sometimes this happened and sometimes it didn't.
I also noticed that when using the GUI Screen that when transmitting that it was quite jumpy.
This does not occur when I was using just a paddle.
Is there possibly a setting I need to adjust within N1MM?
Any help would be greatly appreciated.

I presume you are using COM port keying. This cannot be done so reliably using 'Secondary Key' in ESDR2 1.3 as it was in version 1.2. N1MM should be set up differently. Use the method explained in the UMA, N1MM+ section, pages 52 and 53. You will find it smooth and trouble free, being independent of timing variances.

Erik,
I had some time to make those changes that you mentioned above to N1MM.
I operated last evening during CWT at 25 WPM with no issues whatsoever.
Thanks for your advise.
