The TinyTrak3 was the first TT unit to support HF (300bps) operation. Like the TT2 it also supports a Primary and Secondary profile, allowing the same unit to be easily switched between VHF and HF operation.

The TinyTrak3 has a couple of variant models:

• TinyTrak SMT, a surface mount version
• TinyTrak3+, an update to the original TinyTrak3
• MicroTrak,  various models of self-contained tracker with an RF module built in, based on the TT3 firmware

If you have a TinyTrak3, please consider using the configurations below, where the Primary configuration is the VHF setup, and the Secondary configuration is for HF.
