[Supplement 1]

E1P(Explorer 1 Prime) is a Montana Space Grant Consortium Cubesat-class satellite in development by
the Space Science and Engineering Laboratory (SSEL) at Montana State University. E1P will demonstrate
software technology developed at SSEL that uses a popular chip radio to close a digital data link with
standard ham radio hardware allowing people around the world to contact the satellite and download
science and housekeeping data. E1P F2 is the second flight model.

The beacon is broadcast at approximately 437.505 MHz every 15 seconds.
Any TNC capable of operating in KISS mode can decode the beacon.
The connection of a KISS TNC to the E1P Telemetry Decoder is accomplished
via a serial connection.

DICE-1/2 (Dynamic Ionosphere CubeSat Experiment) will map geomagnetic Storm Enhanced Density (SED)
plasma bulge and plume formations in Earthfs ionosphere. Two identical spinning spacecraft will
measure plasma density and electric fields to determine the how and why of variations in ionospheric
plasma density that affect the performance of communications, surveillance, and navigation systems
on earth and in space.

E1P, Hermes, KySat-1 were launched from Vandenberg Air Force Base at 10:09:45 UT Friday,
4 March 2011 on an Orbital Sciences Taurus XL rocket. The rocket's fairing, the part of the
rocket which covers the satellite on top of the launcher, did not separate properly so the
Taurus XL did not have enough velocity to enter orbit.

The second flight model, E1P U2, was launched through the NASA Educational Launch of
Nanosatellites (ELaNa) program in 28 October 2011 with AubieSat-1, RAX-2, M-CUBED, DICE-1/2.
Those satellites have been separated, but E1P-U2 and M-Cubed by subsequent observation
was found to be that they are flying together to coalesce.

DK3WN observed each satellites which were launched on 28 Oct 2011.

RAX-2 Beacon Decoder, Update

(1) Install python 2.7
(2) Run setup_pyserial.bat
(3) Edit run_serial_to_tcp.bat
(4) Run run_serial_to_tcp.bat
(5) Cancel block in Windows warning message
(6) Edit config.props
(7) Run run_gs_client.bat
(8) Double click run_serial_to_tcp.bat and run_gs_client.bat
    then run_gs_client.jar starts automatically.
(9) DOS_window opens and is finished when you close Decoder.


AubieSat-1 CW

At last I could receive and decode AibieSat-1 CW.
The signal is very weak, but it's exceedingly a clear sound.
