I'm sorry, but a mode that expands willy nilly from about ~500 Hz to 2.5 kHz AFTER a qso has started is just asking for trouble. This is why busy detection will never work really well for pactor 3. If a session starts and someone unknowingly starts another qso ON A CLEAR FREQUENCY besides a pactor 2 qso, they are probably going to get qrm'd!
This is a commercial modem designed to work in a commercial environment where once you seize a channel you OWN the whole 3 kHz channel. Trying to use it in a shared frequency environment is simply asking for interference problems which will only get worse as the solar cycle continues to rise. If you take the time to watch, you will see this occur time after time after time.
