RAX-2 is Alive

Posted on by

RAX-2 was heard by PA3GUO, here is the data he decoded:

First E1P-U2 Recording

Posted on by

I have recorded the following from Explorer-1 [PRIME] I couldn’t decode the data and when I listen to it, I hope I am doing something wrong because it doesn’t sound right.

Audio recording of E1P-U2 at 28-10-2011 12:40 UTC: audio

The signal was very strong ( 9+30db) frequentie used 437.505 MHz FM.

Delta II Launch Successfully

Posted on by

Delta2 RocketDelta II rocket successfully lauched and has deployed his main carco, NPP climate and weather satellite. After that the following CubeSats where also successfully deployed with the P-POD containers.

Confirmed deployment of P-POD-3. This P-POD contains the two-satellite DICE CubeSats
Confirmed deployment of P-POD-2. This P-POD contains the RAX Cubesat
Confirmed deployment of P-POD-1. This P-POD contains AubieSat-1, Explorer-1 Prime, and M-Cubed/COVE

Around 12:30 UTC (14:30 CEST) European Amateur Radio Stations can hear the first transmissions if the CubeSats activate in the right way.

Prospero Audio Files

Prospero audio files recorded on 20, 21 and 24 october 2011. During the recordings I switch sometime from RHCP to LHCP, AM to FW, USB and LSB but most of the recording are in AM modulation.

Prospero-24-10-2011-1755CEST.wav 24,1 MB (No longer available)

Maybe someone can perform some further analyses to see if there are other signals then the ones from the ORBCOMM satellites.

FO-29 Eclipse Undervoltage Stops Operation

Posted on by

FO-29Information has been received that the FO-29 analog repeater is currently off the air. The eclipse periods have increased to the point exceeding 27% shadowing which causes an undervoltage fault to shut down the satellite.

The FO-29 control station sent commands to reactivate the satellite during daytime passes over Japan between October 8-10. Also at the present time the control station was experiencing computer hardware problems which slowed progress.

[Thanks Mineo, JE9PEL, for the above information]
