Most likely the cause in my case.

Radio communications worked fine, no delays.

No packet racquet.

No RF either, as I was S&P, entering the call to see if it was a dupe.

Only on for an hour, rate was about 40 or so an hour, not enough time for disk sleep.

Booted into DOS.

I just noticed this. I normally run CT on my 486DX66 machine without a problem. I was testing out a P-III 600MHz machine this time. It might have to do with the config.sys/autoexec.bat memory setup.
