====== EMF14 ======

  * Pico balloon (100gram Latex) launched on 31/08/14 from [[https://www.emfcamp.org/|EMF Camp 2014]]
  * Onboard:
    * UKHASnet Node (LPC810 based) called EMF14, wire 1/4 wave antenna (not tuned)
    * 1 RTTY tracker with GPS
    * 1 TurboHAB tracker with GPS

===== Flight =====
  * Late afternoon launch
  * Travelled south with a slow ascent rate over London and then out over the Channel into France
  * EMF14 node 
    * Successfully downlinked packets up to a range of 65km (5000m altitude) before was over the horizon/hill
    * No packets successfully repeated
    * Data only downlinked to nodes at EMF Camp, balloon managed to avoid other nodes in Kent and Southampton.
    * Appears that range is approximately 5deg horizon of the balloon (green circle on spacenear.us)
    * UKHASnet website worked well
    * Tested [[https://www.youtube.com/watch?v=bCbf1dv0x-A|hexacopter lifted repeater]] to attempt to re-establish contact but was too far out of range

===== Future plans =====
  * More balloon flights with higher altitudes to test range
  * Better antennas on ground for uplinking.
  * More ground nodes
