We are sorry to report that Pocket Tracker is no longer available. It was discontinued because some of its parts were obsoleted and replacements have not been found. This page remains for reference.

However, Byonics now carries a similar product, the Micro-Trak 300.

Pocket Tracker FA

The original Pocket Tracker by HiValue Radio is a 2-meter FM transmitter combined with a TinyTrak3 that provides an easy and inexpensive way to build an APRS tracker. It is able to transmit on one of two pre-programmed 2-meter frequencies.

Michael Pendley, K5ATM, has developed a firmware modification for the two-meter transmitter portion of the Pocket Tracker that makes it Frequency Agile! The new modified Pocket Tracker, called the Pocket Tracker FA, allows the user to easily change the programmed frequencies using any computer that supports a terminal emulation program such as Hyperterminal.

The FA option allows experimenters to do even more. The same terminal emulation program allows experimenters to become familiar with the MC145170 Phase Locked Loop (PLL) by allowing them to control the individual PLL registers and the transmitter's power amplifier.

The Pocket Tracker FA has all the features of the original Pocket Tracker, uses all the same cables, and in default mode operates essentially the same. The default frequency is 144.39 MHz, and the alternate frequency, selectable by moving J11, is 144.34 MHz. The Frequency Agile Pocket Tracker option allows the user to set the primary and alternate transmitting frequencies. Recommended range: 144 to 146 MHz.

The Pocket Tracker FA is available as a kit, just like the original Pocket Tracker. There are only minor assembly differences. Three parts are added to support user-configuration of the special transmitter PIC (U6) firmware: D10, J14, and R33.
