Project pagina voor het high altitude balloon tracking/listening station dat we voor de space aan het inrichten zijn.

"ezcap USB 2.0 DVB-T/DAB/FM" dongle, RTL2838U, Fitipower FC0013 tuner, Supported gain values (23): -9.9 -7.3 -6.5 -6.3 -6.0 -5.8 -5.4 5.8 6.1 6.3 6.5 6.7 6.8 7.0 7.1 17.9 18.1 18.2 18.4 18.6 18.8 19.1 19.7

Raspberry Pi
Test payload, RFM22b sending RTTY strings on 434.250MHz. Code here: https://github.com/costyn/rfmtest/blob/master/rfmtest.pde

Sending test payload --> works!
Using rtl_tcp from RasPi over network --> works!
gqrx to listen to audio --> works! (250000 samples/seconds), freq seems to go even up to 434,227,925 (center 434,225,517)
dl-fldigi RTTY decoding --> works!
rtl-sdr compiled from git on Raspberry Pi: --> works!

revspace@habraspi:~$ rtl_tcp -a 10.42.43.20

Found 1 device(s). File:Finaltestonpi.png Found Fitipower FC0013 tuner

Using ezcap USB 2.0 DVB-T/DAB/FM dongle

Site survey roof, check if there is already some sort of lightning protection system, and see if we can add some metal construction to it ourselfs
Currently we have no antenna. Well need some heavy duty (directional?) antenna.
- Do we make one or do we buy one?
- What kind of antenna? (keep in mind we only have line of sight towards south/southwest)
Enclosure spec-en en aanschaffen
Routing 230v and Ethernet towards the roof
Your ideas, we love them!
