Hi Clay,
That would be neat but at the cost they go for highly doubtful.:-) ;-)
Ummmm, one of those cheap SDR dongles can do some rudimentary signal
analysis on an Android for $30.00. Apply the ElementalX solution:Nexus 7

and you can have the dongle attached to the OTG port AND have external power
applied atthe same time. Only issue there is one loses the ability to just
plug in a memory stick aloneCan still do that with a Y cable with a power
source attached. Can use external power alone also.Can easily and
non-destructively reset the option if you don't like it later.
Actually their Tele-GPS sends out their telemetry and can do an
APRS packet nicely. Their other units can do APRS if one can
go without all the other real time information.
The Tele-GPS is the smallest available GPS rocket tracker out there and
I was able to put it into the nosecone of a 38mm minimum diameter
Go Devil 38. I've has 5 sight unseen flights with other rockets and
the Beeline APRS trackers got 'em back every time.
On the radio, I hear the Altus-Metrum data packet and the APRS packet.I think
sending two different sets of data at about the same time quite a trick.One can
still use an APRS H/T interfaced with say a Garmin 60CsX to be able togo
portable to the recovery site.
Triapsing around with a laptop is a real PITA. The TeleBT helps in that regard
of
having a portable solution with the Altus-Metum hardware.
I am not a programmer but if Altus Droid could decode APRS packets the Beeline
APRS crowdwould likely buy a few of them. Geez that nifty receiver mounted on
the antenna beam.That is a great way to go!

why not ask for a spread spectrum analyzer while your at it

[altusmetrum] TeleBT v3.0 is here! What would be cool is if the TeleBT could
decode plain APRS packets and place them on the map.Those fliers who also fly
70cm APRS trackers would have a killer ground station to decode the telemetry
from their Altus Metrum "flightware" and generic 70cm APRS trackers they might
already own. The real kicker with the TeleBT is the ability to use AltosDroid
with a phone or tablet.Am just itching to get it going with a Nexus 7 2013.
I'd like to mention to others if going to do the same,they might want to
consider screen glare protection for whatever device they're considering to
use.I found a small semi-deep box I cut a thumb hole in for single hand use of
the N7. I painted the inside with flat black paint and boy does it help in
making the screen readable in bright sunlight. Yes I have one of those "flat"
screen protectors that is supposed to cut down on glare but it only goes so
far.If you have a device that is resistant to glare, you're in the catbird
seat. The size of the box comfortably holds the N7, an additional auxiliary OTG
battery pack and a receiver. Alternatively, could hold a Ham H/T with a
Mobilinkd TNC (http://www.mobilinkd.com/) to use APRSDroid (that has portable
maps, no internet required). Or............. can hold an EggFinder LCD receive
station and track with GPS rocket locator. For bright sunlight conditions I
still like my D72A and Garmin 60CsX for the 70cm trackers. The 60CsX can be
had for a reasonable cost on Ebay and I picked one up where it looks like it
was used only two times like the seller said.The handheld Garmin is designed to
be readable in the sunlight.No problem with maps as the OSM maps can be had for

Only problem with OSM maps is the "points of interest" database is very
incomplete so if expecting to find restaurants and suchis not good. But.....
good to have an up to date map if that is important for the flight venue one is
at to discern roads for recovery planning. The combination APRS H/T and Garmin
handheld was very pricey but was the only game in town 9 years ago. Lock on
rocket while still on the pad and no muss or fuss........ Just like the Altus
products except there is more real time data available and if all that
information is not needed, can use an APRS receive station for tracking Kurt

If your TeleBT is working, just keep using it and live happy!
TeleBT v3.0 has better receiver sensitivity, and can be re-flashed over
USB, but is otherwise functionally equivalent.
