Listening to a Radio Amateur Stratosphere Balloon with an RTL-SDR
Over on YouTube user kpappa has uploaded a video showing his reception of the J43VHF radio amateur stratosphere balloon with an RTL-SDR dongle and discone antenna. On the 10th of May radio amateurs in Greece launched a high altitude balloon. The balloon carried a transceiver payload which allowed amateurs to talk to each other via the balloon at a frequency of 144.200 MHz. The video shows good reception of the balloon and also shows it’s tracking via APRS.fi.
More information about the balloon can be found at https://j43vhf.wordpress.com/ and http://hellashab.blogspot.gr/.
A team of the SatNOGS project (featured in previous rlt-sdr.com posts) has tested their rotator equipment in this balloon flight too: https://satnogs.org/2015/05/satnogs-hab/
