      APRSIS32+AGWPE RX only I-Gate on 144.390MHz launched at my QTH this morning.
      Hopefully balloon survived and it's equipment works well and... it will choose path close enough to Poland ;-).

      If it comes across further North and is picked up by UK stations then Dutch
      stations monitoring would be good also.

      Just sent the following to a lot of Stations in Western France

      Please can you help, we are looking for stations in Western France to
      monitor APRS on 144.390MHz for a balloon crossing the atlantic K6RPT-12, if
      it makes the crossing it should be heard about 12:00UTC if your APRS Station
      is not internet connected please send reports to myself. Thank you Steve

      S'il vous plaît pouvez-vous aider, nous recherchons des stations de l'Ouest
      France pour suivre APRS sur 144.390MHz pour un ballon de traverser
      l'Atlantique K6RPT-12, si elle fait la traversée il doit être entendu parler
      de 12:00 UTC si votre station APRS n'est pas connecté à Internet s'il vous
      plaît envoyer des rapports à moi-même. Merci Steve

      I think they got permision for DStar a few months or so ago, not 100%
      sure, but I don't see why an RX only igate would not be alowed in france.
      nobody is likely to transmit on 144.390 anyway because it is just below
      the beacon band

        It sure did! It was one of these devices.

        http://www.bigredbee.com/blgps_2mhp.htm

        It was used to observe and track the flight from California all the
        way to Morocco as seen here:

        http://aprs.fi/#!mt=roadmap&z=11&call=a%2FK6RPT-12&timerange=604800

        All one needs to do is get closer to the landing area and listen for
        the signal on 144.390. You don't even need to decode the packet to
        recover. If you hear ANY activity on 144.390 in the area, it is most
        likely the payload. Use RDF techniques to triangulate the final
        resting location. APRSISCE/32 has the ability to plot RF directionals
        and omni DF plots, which would be a great tool to use for recovery
        efforts

        If you had APRSISCE/32 connected to your radio, the program could plot
        any position packet that was successfully decoded once you got close
        enough.

        Sometimes we forget that the whole purpose of the APRS transmitter on
        board these payloads is to beacon location information which can be
        used to determine the landing location for recovery.

        That's what we use all the time to recover all our balloon payloads.
