Designing a lab model
The Arctic Tracker project is not dead (yet). The idea is to develop a tracker device with traits like these:
Receiving APRS packets
Receiving and decoding of APRS packets is now implemented and it seems to work. It is more tricky than sending
Transmitting APRS packets
APRS packet transmission is now tested and it works. It is clear that the SA818 radio module is not usable
Using the DAC
Can we use the 12 bit DAC of the Teensy 3.1 to generate AFSK (Audio Frequency Shift Keying) signals? Lets
Hacking the radio module
It works. I connected the SA818 module to the Teensy 3.1 and wrote some code to control it. I tested
Towards a next generation tracker
The Polaric Tracker developed by LA3T was just the right APRS tracker for search and rescue services. Now the question
ArcticTracker
After a somewhat successful campaign from LA3T, the PolaricTracker where born, and with it PolaricServer and PolaricApp. Unfortunately, for unknown
DACS proof of concept
During the LA8HTH event August 13th-14th 2011 (Ham-treff Helgeland), a bunch of us set out to complete a proof of
freqDB – RF spectrum systematized
A couple of years ago I was searching for a decent database to look up repeaters, nodes, beacons etc. To my surprise,
