[Xastir] TM-D710 config file

[Liz VK2XSE]

With the loss of another aged GPS dongle I am back trying to get Xastir
to use the GPS attached to the transceiver.

I am getting the GPS data from the transceiver head, but Xastir is not
accepting this data
I have in the startup config

(the last lines)
GBAUD 4800
GPSTEXT $GPRMC
LTMH ON
LTMON 5
#LTMHEAD ON

I have the interface set for Serial TNC with GPS

I get in the TNC log
one of these each 5 secs
# 1361839780  Tue Feb 26 11:49:40 EST 2013
VK2XSE-9>GPS:$GPRMC,004936,A,3415.9935,S,14606.8214,E,000.0,012.2,260213,010.9,E*61


Xastir says it is delaying transmission until it has a valid GPS fix
Checking the GPS status it still says it doesn't have a valid GPS fix
so no transmission occurs.

Can someone assist with the last bit of configuration?
