So the plan is to make a morse beacon that pulses on and off at 1Hz and then every minute the gm862-gps takes over and pulses out the time,lat,long and alt. To achieve this without using a complicated PIC I've got hold of some CMOS 555 ICs which will be set up to pulse the radio at 1Hz and the GM862 will pull the reset to ground and toggle the pin itself.
