That is really strange. It is normal for Windows to key the PTT when
Windows starts. You will hear a beep-beep, a pause, another beep-beep,
and other pause and a final beep-beep. I occasionally hear that
transmitted from somebody over the air so I know it isn't only me. :-)
But to continue transmitting after that is very odd. What other
programs are running at the time. If you have NO other programs
running, does it still happen? How about if you use MSCONFIG to
disable the startup programs and also disable all non-Microsoft
services?
