ARLA/CLUSTER: Australia vai lançar um radio-balão este sábado com frequencias em 40, 30 e 20m

[João Costa > CT1FBF]

Ham Radio Balloon on 7, 10 and 14 MHz

This Saturday, Australian radio amateurs will launch a HF balloon
PSB-5 transmitting WSPR and Slow Scan Digital Video (SSDV)

Our PSB-5 balloon launch will be from Bendigo this Saturday, November
16, 2013 at 11am.

The details:

- 434.65MHz USB for telemetry and SSDV images. RTTY 450Hz 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 25mW 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
http://webchat.freenode.net/?channels=PSB

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 softwares

http://www.physics.princeton.edu/pulsar/K1JT/wsjtx.html and
http://physics.princeton.edu/pulsar/K1JT/wspr.html

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.
