txd = txdelay, if you have a PLL transmitter then the txd delay needs to a
litte longer than with a xtal trx, what probably was happening was you
started to send data before your TX was locked, therfor the first few bytes
get lost, and no one can decode your packets, the same happens with SCC and
Baycom with TXTail, if its to short.

There is a program called 'beacon' which broadcasts a defined string, i do
for example.
beacon -t30 scc0 "PA3GCU-2 =chat PA3GCU-9 =NET/ROM node"
Of course if others do not monitor the channel they still wont know, but
then you could put a message into /etc/ax25/node.motd which is transmitted
upon a connect to node.
For chat i use the excelent ttylinkd program from Craig Small.
