First project for 2017

Mine will have Anderson PP instead of an auto-type DC plug
Happy New Year!

I've just ordered the ingredients for a new project for the year - a Byonics Micro-Trak RTG FA. This is a complete 10-watt APRS tracker in a plug-n-play package.

I've dabbled in APRS before using cobbled-together components from a variety of manufacturers and it resulted in a spaghetti mix of cables, wires, adapters, etc that didn't lend themselves to being easily moved from one vehicle to another. This set-up is compact enough to be used in a car one minute and on a motorcycle the next.

It will likely see use in both of those applications but I also want to see if it is sized (electrically speaking) to a 20-watt solar cell I have along with a 22AH AGM battery. The purpose of that would be to have it installed on our travel trailer so that family & friends could see where we are. Last year's motorcycle trip with a satellite tracker for safety proved informative and useful but costs $30/month for the service. APRS will do the same thing (in most locations) for free.

Determining the power requirements for such a device is almost impossible. Or at least impossibly tedious since the duty cycle is variable. Once I settle on a transmission rate, the plan is to set it up as if I were on the road and let it do its thing while an inline power meter records all the pertinent power info.

  1. Sounds like fun. Keep us posted on what happens! I am looking at getting back into APRS this year as well.
