I realize you are using the TNC-X where the TXDelay is set with a pot, 
but for anyone using another TNC where it is set in software, 250 to 400 
ms is usually much longer than needed. I have reliably used less than 
100 ms, regularly use 100 ms and suggest about 125-150 ms for someone 
that doesn't want to take the time to see if shorter TXDelay can be 
used. Yes, if it's too short, no-one will be able to decode your tones, 
but set too long, and it uses up valuable bandwidth.
