A few weeks ago I built up a Foxtrak kit, see Foxtrak build.
During testing, I noted that VK2ZEN-5 occasionally corrupts Foxtrak packets, or more generally MIC-E encoded packets. It is a known problem with aprsd which has not been fixed in more than 10 years.
As a result of the fact that one local digi (OT3) never decoded the Foxtrak (DK7IN firmware), I tried aprstracker0.11 and original TinyTrak(1) firmware.
The aprstracker evaluation is described at Review of APRSTRACKER v0.11 firmware, it was unsuitable.
The TinyTrak(1) firmware didn’t work with the OT3 digi either.
The matter of Foxtrak / OT3 interoperatibility is discussed in more detail at:
- Interoperability of FoxTrak tracker and Argent Data’s OT3 – Part 1; and
- Interoperability of FoxTrak tracker and Argent Data’s OT3 – Part 2.
A TinyTrak3+ was also evaluated, see TinyTrak3 v1.42 review.
Considering quality, price and performance, the Foxtrack works with most digis types but not OT3s, the DK7IN firmware has more feature than the original TinyTrak, but the combination is nowhere near as capable as the TinyTrack3+ which is less than double the price as landed in Australia.
