[OZAPRS] Project Horus planning high altitude balloon launch forApril 15th with APRS and FM Voice

[Nik Presser]

G'day Grant, 

Nice work on Project Horus - I've been interested in what you guys are doing for quite a while. I'm looking forward to tracking it this Sunday. 

I note on the Project Horus website that you will be running net control through the VK5RSB repeater. I think this repeater is/was linked to IRLP 6214. Are you going to be leaving this repeater in standalone mode this weekend or would you perhaps be linking it to one of the Adelaide IRLP reflectors so that a few of us could also link to the Reflector and listen in?? 

You guys are doing a great job - very interesting. Keep up the great work!!  :-)

Cheers,

  Folks,

   

  Here is a preliminary heads up, the Project Horus group in South Australia are planning on launching a balloon during the WIA Field Days event on Sunday April 15th. Lift-off is planned for sometime just after the WIA broadcast (say around 10.30-11.00am ACST).

   

  Horus 23 is planned to be a combined FM Voice repeater and APRS flight - using the new club callsign VK5ARG-11 on APRS. The FM voice repeater will be a 70cm uplink / 2m downlink crossband system, like the one we flew on Horus 9. The frequencies for the voice system will be confirmed and released shortly. (Just checking some intermod/desense stuff first). The usual 300baud RTTY telemetry payload will also fly (434.650 at this stage will be the beacon channel).

   

  Plans at this stage these are still subject to the weather. With this payload, we will only release the balloon if it is going to safely land in the Mallee east of Adelaide, so looking from this far out, it is possible that  the mission could be scrubbed. Having said that, we are quietly confident, and are commencing launch preparations on the assumption we will get to fly.

   

  When at apogee, at 20-50W 70cm uplink should be able to access the repeater from up to 800km away from the balloon so contacts across a large portion of central SE Australia should be possible. The 2m downlink should be easily audible.

   

  For more information about Project Horus, check out the groups website http://www.projecthorus.org/ or the group's Vimeo TV Channel http://www.vimeo.com/channels/projecthorus

  Grant VK5GR
