    they really really should not be using wide2 or any other digipeaters. from that altitude, it's a QRM factory with a wide2 path. just beaconing would be plenty. if the device is smart enough, have it use a wide path ONLY below 1000' if you would need APRS to find it once it lands.

    Seems to be something wonky with the altitude readings as far as I can tell from the raw packets on aprs.fi. For some reason, occasionally the altitude is getting 3 zeroes tacked on to the front, pushing the 3 least significant digits out the other side. So A=111408 becomes A=000111 in the next packet.

    Aaaaand it's now in Canadian airspace over Sarnia.

    APRS newbie here so I'm likely way off the mark but I did a little googling and found these sites, both of which explicitly state that aircraft should use WIDE2:

    Would appreciate a little bit more explanation. Thanks.

    from that altitude, a wide2-2 packet will hit easily dozens of digipeaters, which will then repeat the packet as wide2-1, and then easily dozens more digipeaters will repeat the packet AGAIN, probably to hundreds of igates. so whats the goal? to see the packets on the internet like APRS.FI, or to have the packet heard by every man, woman, and child with an APRS receiver on the continent? just a plain beacon from 50Kfeet will hit several igates and map just fine on the internet without bouncing packets all over the continent.

    Their twitter feed mentioned that the low temperature is messing with the GPS. Based on that, it's unusual that it's doing it now, in full daylight.

    It's only operating in Wide2-1, but I agree it shouldn't be using digipeaters above a certain altitude. It's a big-red-bee, so it doesn't have the functionality to do such things. it's not aggressively congesting the network (although it doesn't need to beacon every minute whilst cruising) and it's important for the last few packets to get through the network to pinpoint its crash location.

    HAD WE KNOWN IN TIME, WE COULD HAVE SENT UP AN INTERCEPTOR AND BROUGHT THAT BABY DOWN. Next time.

    it went right over my house. could have keyed up 1500W on the EME antenna and lit it up good :)

    At 20:25Z the balloon, signing the callsign K6RPT-12, is at the Vermont/New Hampshire border, still at an altitude of around 112,000 feet. There continues to be intermittent erroneous reports of it's location being south of the apparent real track. These bogus reports show an altitude of around 100 feet, then the next reports seem to indicate that the balloon is still at an altitude of around 112,000 feet. It appears to be on its way to Europe. I wonder what the steering winds are over VO1/VO2 land, where it is headed.

    The wide digipeating might start to make more sense if it heads out over the North Atlantic - which, as of this writing, it's looking to do in about 30 minutes.

    So forgive my ignorance.... but the purpose of this exercise is - what? What new ground is
    being broken or tested or whatever? Or is it just a "for fun" project?

    Anyone worked out how long at its present speed it would reach Ireland/UK/Europe?

    almost to nova scotia, then ocean!

    --Congrats! Looks like a neat project. It was nice to see the path it has taken on the website. +200MPH and 110,000+ feet!

    The balloon came over my area this morning about 4am local. Here is what data I captured on my FT2800 using an Isopole antenna.

    I think the joker here is going to be the difference in APRS freqs in US and Europe, shame that hadn't been thought of, UK has quite a big APRS network which won't be able to track it

    WA7AWK,
    Dave,
    You asked, "What new ground is being broken or tested or whatever? Or is it just a 'for fun' project?"


    Well, being involved in a tracking a number of high altitude balloons, I can tell you that for at least me (and probably many others) it IS fun. Even more so is tracking the balloon's bigger brothers, satellites. But launching balloons is done for more than just fun.


    High altitude baloons with APRS transmitters on board expose the many students involved to a meriad of technical skills. They learn how to fabricate pay-loads that can survive the severe environment of space, how to launch and track the balloon, and to copy, decode and evaluate telemetry for various experiments that are flown. Because of their involvement with these high altitude balloon flights, the hope is that some of the students will pursue a career in science, technology, engineering or mathematics. Many will become the future aerospace experts of the future.


    Good enough reasons?

    M6SOE,

    I would guess that in about 20 hours it will be approaching the coast of Northern Spain or Western France.
