[ct-user] "Stutter" in transmitted CW

[Ken Wolff]

CT9.37 has gone to full duplex on the COM ports. That means CT will send and
receive simultaneously on the RS232 lines. Based on this, I think the 1000D
(and others) can't handle RS232 send, RS232 receive and CW sending
simultaneously.

I now need to interlock CT to stop sending while data is arriving.

I believe I was running from "real" DOS by selecting the "Restart in MS-DOS
Mode" from Windows 98.  I should have added to my original post that I was
keying with my Vibroplex paddle using the rig's internal keyer.  I did not
have CT hooked up to key the rig.

Were you running in a DOS box under Windows, or "real" DOS?

Thanks - Ken

I definitely had the same problem with CW stuttering.  I did not realize it
until several hours into CW SS.  I thought that everyone was getting rusty
receiving CW -- Hi Hi.  Once I figured out the problem, I had to disable
radio polling to get the stuttering stopped.  Later in the contest, after
the problem was fixed, a half dozen dupe stations called me.  It seems they
must have incorrectly copied my call due to the stuttering!!!

I was running 9.37, FT1000D, and Pentium II - 400.

Switched from v9.31 to v9.37 just before SS.

Never seen in previous versions, but 9.37 seemed to sometimes
"stutter" on sent CW characters.....

Not consistently, but often enough to be bothersome, it would mangle
a character by inserting a "mini-pause" between character elements...

...for example the number "0" might sound like "MO" because of a
little glitch between the 2nd and 3rd dash, or "B" might be sent
as "NI".  The pause is not enough for a "full" character break, but
definitely confusing.  On average, I'd say the "stutter" occured
once every 10-15 QSO's.

I've used v8.xx, 9.20, 9.21, 9.31, and now 9.37.  This problem was
NOT in these earlier versions I have used on this same computer
(a venerable Compaq 486-33).
