[OZAPRS] TT4 Switchable?

[Michael Wain]

Hi Geoff,

In the TT4 Tracker config software set Primary window with the 300 Baud
packet box unticked, in the 

Secondary window set 300 Baud packet box ticked, save setting, then run a
wire from pin 5 on U1 (sw1 pin ) 

to pin 4 ( unused pin ) on J1, then you can run a wire from the db9 plug
pin 4 to a switch, open circuit for Primary mode,

Ground/neg for Secondary mode. works with the tt3p but the wire on U1 pin
5 to pin 4 on J1 is already setup on the tt3p

Jumper J5 and J6

These holes are available for input or output switches. For the TinyTrak4
APRS Tracker, J5 is SW1, used to switch

between primary and secondary configurations and J6 is SW2 used to control
power to the radio or GPS
