OpenTracker1 has a noise sense, similar to a TinyTrak unit.

OpenTracker2 has full receive capability so can do more yet.

I have my OT1 in the Jeep tied to the speaker out of the mobile rig.
When the squelch opens it won't transmit.

The OT2 will be able to run open-squelch all the time, making one
less adjustment that can screw up my tracker.
