Micro-Trak TinyTrak4

The Micro-Trak TinyTrak4 (MT-TT4) is a Byonics TinyTrak4 controller combined with a single channel, crystal controlled, 500mW radio transceiver on the North American APRS freqency of 144.39 MHz. The MT-TT4 can act as a tracker (with added GPS), KISS or UI Text TNC, APRS Digipeater, and packet display, all at the same time.

The MT-TT4 utilizes a special configuration of the TinyTrak4 microprocessor, and a special version of the firmware to control the aspects of the transceiver that are unique to the MT-TT4. Firmware versions for the regular TT4 will not work and should not be loaded into MT-TT4 processor. New versions of the MT-TT4 firmware may be freely downloaded here and installed in the MT-TT4. Refer to the TT4 manual for instructions on loading firmware and setting software values and parameters.

The MT-TT4 has a DB-9 connector with 2 serial ports, an RJ-45 connector for a remote display, a PS/2 connector for keyboard support, and an RJ-45 connector for telemetry inputs. A F-F Null model adapter or cable is needed to connect to a computer. It has a threaded SMA connector, so it can take any of the Micro-Trak Antennas, or other standard amateur SMA 2-meter antenna. A two-part black case is included.

Please Note, the MT-TT4 should NOT be used with the original Micro-Amp, but can be used with the Micro-Amp 3.

Ordering:

The MT-TT4 has been discontinued. But look forward to our new MT-AIOIV, with built in GPS and Bluetooth, coming soon.
