Eric and Marc,

Thanks for the replies.

Marc, I have the Colibri set up following the Winpilot recommendations
of GPGGA and GPRMC outputs. I can try turning them off one at a time.

Eric, I checked and the IR port is turned off. So hopefully that is
not the problem.

I will try some test to see if things improve. I would like to get
this all worked out before heading to Ely next week.

Thanks,

Tim
