[NLRS] APRS for rovers

[Stephen Hicks, N5AC]

Jon,

I run about 40W on my tracker and have great coverage... The beauty of APRS
is that the silly thing will transmit about once a minute while you are in
motion (turn on smart beaconing in the Tiny Tracker) and it only takes one
packet received to get your position across.  So while in the boonies you
may miss a lot of packets, when you top a hill, one will get through and
you'll show back up again. No brick required!  When you stop on a hilltop to
operate, the algorithm will stop transmitting except every now and then (5
minutes?) so it rarely interferes with weak signal work.  Just an occasional
**belch** heard on 2m for about 1-2s every 5m.

Steve, N5AC

Hi Mark, thanks for the input.   Assuming one has a 2m FM rig and a GPS
(most rovers do), it would appear that for perhaps $35 (the cost of the
Tinytrack product) that one can be "located".   I would think that for the
rovers that are heading out to the wide open spaces that a 100 watt brick
may be a desired option .... gosh, this is going to put a new surge in
demand for 2m bricks on eBay.

Thanks to everyone who had response & input on the APRS/rover discussion.
It really does look like a fun technology that may merge well with roving
(and visa versa).
