Good basic circuit board
|
Time owned: more than 12 months

I constructed two of these boards for APRS tracking. It is essentially similar circuit as TinyTrak3. I had problems with RF feedback with TinyTrak3 (with Icom IC-V8) and found the problem cleared with FoxTrak. Foxtrak has a larger ground foil area, the circuit elements are flat to the foil giving it a smaller chance of RF feedback (compared to TinyTrak perpendicular elements) and several extra capacitors across the power supply and ground to minimize noise. I also tried the Foxtrak-m which gave me RF problems.
Where Foxtrak lacks is the supplied main chip programmed with less features. I simply substituted a TinyTrak chip. If you set the jumpers right you can run it as a TinyTrak3.
