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

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 free here: Free worldwide Garmin maps from OpenStreetMap Free worldwide Garmin maps from OpenStreetMap Free worldwide Garmin maps from OpenStreetMap, available in Basecamp, MapSource, RoadTrip and gmapsupp formats for Windows, Mac OSX and Linux. View on garmin.openstreetmap.nl Preview by Yahoo Only problem with OSM maps is the "points of interest" database is very incomplete so if expecting to find restaurants and such is 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 Savegnago KC9LDH -------------------------------------------------------------------------------- From: Bdale Garbee <[email protected]> To: Dennis Lappert <[email protected]>; 'Altus Metrum' <[email protected]> Sent: Thursday, July 16, 2015 10:31 PM Subject: Re: [altusmetrum] TeleBT v3.0 is here!

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.
