This Saturday, November 16 Australian radio amateurs will launch a HF high altitude balloon, PSB-5, transmitting WSPR, JT65, THOR and Slow Scan Digital Video (SSDV).
Our PSB-5 balloon launch will be from Bendigo, Victoria this Saturday, November 16, 2013 at 11am local time (0000 UT).
- 434.650 MHz USB for telemetry and SSDV images. RTTY 450 Hz shift, 300 baud, 8 bit ASCII, no parity, one stop bit.
- HF for telemetry, on 20m, 30m and 40m in alternate time slots. The protocols are WSPR, JT65 and THOR4.
- Hardware includes a Raspberry Pi computer with Pi-Cam, and 25 mW UHF tracker.
Using JT65 and THOR on dial (USB) frequencies of 7.0285, 10.1405, 14.0785 MHz
with WSPR on dial (USB) frequencies of 7.0386, 10.1387, 14.0956 MHz
PSB-5 balloon positions will be uploaded to http://spacenear.us/tracker
SSDV images will be available at http://ssdv.habhub.org or on dl-fldigi if you receive SSDV directly.
On the day we will have a co-ordinator in #PSB IRC chat room on freenode.net
To receive balloon data you will need access to SSB HF and UHF radios.
Dl-fldigi can be used to decode THOR4 and RTTY/SSDV.
JT65 and WSPR require their own software
Please see http://projectspaceballoon.net/ for details.
Pre-flight test HF transmissions were received from as far as VK6 for JT65 and USA for WSPR.
The reception range for HF transmissions from the balloon should be all around Australia and NZ when the condition is good.
Assistance with tracking is greatly appreciated.
