I was able to receive up to 10KB (size of the resulting .funcubebin
file) of Telemetry from FUNCube-1 (AO-73) here at my home in Havana,
Cuba, (EL83sc) during the 03:41-03:52 UT pass of Nov. 26th.
I used a MAR-8 MMIC pre-amp with ZERO filtering, a QFH antenna and a
cheap RTL-SDR dongle. Software was SDRSharp with Plugin for Doppler
Control and Orbitron as Sat Tracking Software.
Even with the poorly filtered and not too much sensitive RTL-SDR dongle
the signals amplified with the also poorly filtered MAR-8 pre-amp was
VERY STRONG even in complete Eclipse.
I used Virtual Audio Cable software to feed the demodulated audio into
the FUNCube Dashboard software and it was very smooth. I am very happy
because after many days being busy I was finally able to get some free
time to try listening to FUNCube. CONGRATULATIONS TO ALL THE FUNCUBE AND
Today at the GROS (the Cuban Satellite Group) we created and registered
an account in the FUNCube Warehouse data server to upload all the
received Telemetry. The most common Internet access in Cuba are at
workplaces which usually has a proxy server for Internet navigation and
the FUNCube Dashboard has no proxy compatibility, that's why many of our
hams cannot upload directly the received telemetry frames. To overcome
this issue and to contribute with the telemetry forwarding the GROS_Cuba
user was created and we will be sending the telemetry through a direct
Internet line at IGA (Cuba's Institute of Geophysics and Astronomy, see:
www.iga.cu). This morning a total of 124 frames received from Hector
CO6CBF and Pavel CO7WT were uploaded.
Tomorrow I will upload more telemetry received, including the frames
received by me and also Pavel's and Hector's data in case they have some
more frames from today.
