The Best Tracker on the Market?
 
My 10 years old BigRedBee APRS tracker is faltering and I am thinking of replacing it with something more robust and modern. Any recommendation from seasoned hams? Which tracker is the best? I am not a tinkerer and wouldn't build my own. :)

MicroTrak RTG
 
I'm happy with mine that I bought a few months ago. Install cant be any more simple.... http://www.byonics.com/microtrak/

Ok I'm stupid. Whats a tracker (in this context) and why would one want to buy one? Why do HAMs use it?

Micro Trak
 
Has anyone used the Micro Trak AIO (all in one)? It looks like it could have multiple uses with the battery power and attached rubber duck antenna.

Mani,

These are little (physically) ham radios put in a wing or other place in an airplane and which put out a signal that is then connected to the internet (look at aprs.fi, for an example) and anyone can see where you are at any given time (within a few minutes). Of course if you want to be in stealth mode, just turn off your transmitter (tracker). It is a cheap alternative to things like spidertracks or spot, but it does not provide all the capability of those things.

Also, it is used by a bunch of other folks (autos, boats) so you have to filter those out.

That's it in a nutshell. Search on aprs on here for more detail.

Greg

P.S. to legally use one, you have to have a ham radio license, which is pretty easy to obtain.

Ok thanks Greg. I wiki'ed APRS and after reading a bunch of gobldie-gook I did finally figure out it was kinda SPOT-ish. Just wasn't sure why HAMs were the center of it all.
I get it now.

Vlad,

I like the idea of receive before transmit and this unit seems to be doing that:

It gives you more of a chance that your packet will be heard. It also has plenty of power at 8 watts.

It can also receive messages via APRS. Would be cool if someone made a messaging app for it.

The problem with airborne receive before transmit
 
is that you'll never hear a quiet interlude on a packet channel on 2 meters. Ever.

Better to transmit in the blind, at a reasonable output power and interval, and hope for no collisions. Listen-before-transmit is good etiquette and good engineering for land-mobile stations and of course digi-peaters. It's pretty impractical for airborne trackers with any receiver sensitivity at all.

Hamming way longer than I've been aviating

Not saying you should necessarily take on a tracker DIY project, Vlad, but when the WX has you grounded, unless you're building another plane, I'm hard-pressed to think of a better alternative hobby than diddling with radio transmitters, receivers, antennas - and modern ham accesories like modems and computers. Anyone technical enough to build an RV and get a pilot's license should have no difficulty getting savvy enough with electrons and radio frequency energy to have some real fun with it. Plus, you're already licensed. :p

Go for it.

Plenty of stickies in the VAF APRS sub-forum:
