gps not work

[3dfablab]

HI, I guess is somethings I don't understand in this tnc....but why cannot send any packet from gps in tracker ..mode..? I mean, is there a baud rate for gps? is it 9600 ,4800, or every one work??
It work as beacon..no problem , it work in conv mode...I was on wb8wga site to see if there is a cmd for that...they use a jumper wire to work in tracker mode ...
If you can help me in solve this , please do.
Great job for the new pico...
tnx de iw0hjz alberto
