Subject: [amsat-bb] FASTRAC Digipeating Announcement
From: Sebastian Munoz Toro
Date: Thu, 1 Dec 2011 01:18:07 -0600

The FASTRAC satellites have been in operation for more than a year and the
team has been able to get a lot of data from them, in great part due to
the amazing support from the amateur radio community. Over the last month
the team noticed that one of FASTRAC-1’s on board microcontrollers which
controls one of the experiments has not been booting up correctly.

The team has done everything possible to correct this issue apart from
turning it off which can only happen if the batteries fall below an specific
charge level. Since the satellites have been power positive throughout this
whole year the only way this can happen is if the satellites transmit more
often. Given that one of FASTRAC goals has always been to eventually provide
a platform for amateur radio enthusiasts to use after the primary mission
was over, the team has decided to open up FASTRAC-1 to the amateur radio
community with the hope as more people use it to digipeat through the
satellite, the battery levels will diminish and cause a hard reset of the
microcontrollers on board. The satellite will be configured so that amateur
radio operators can use it beginning on Friday Dec 2 at 10:00 AM CST.

Starting on this date people will be able to digipeat through the satellites.
The call sign and frequencies of the satellite are summarized below and an
example of digipeating through the satellite is also shown in below.

To increase the chances of causing a hard reset, it is requested that as
many amateur radio enthusiasts try to digipeat through the satellite on the
weekend of Dec 10. If you are successful at digipeating through the
satellites or have any problems doing so please let us know at fastracsats@
gmail.com, through our Facebook page (http://www.facebook.com/fastracsats)
or through the forums on our website
(http://fastrac.ae.utexas.edu/for_radio_operators/users/phpBB3/index.php).

Frequency Information for FASTRAC-1

FASTRAC-1 "Sara Lily" Downlink Frequency: 437.345 MHz
FASTRAC-1 "Sara Lily" Uplink Frequency (1200 or 9600 baud): 145.825 MHz
FASTRAC-1 "Sara Lily" Satellite Call Sign: FAST1

Example of Digipeating through FAST1

cmd: c CALLSIGN via fast1
cmd: KE5DTW>CALLSIGN,FAST1/1: <C>
CALLSIGN>KE5DTW,FAST1*/1: <UA>
*** CONNECTED to CALLSIGN VIA FAST1

Here the example shows KE5DTW (UT Austin Ground Station) digipeating through
FAST1 to connect to CALLSIGN. CALLSIGN represents an arbitrary callsign and
should be replaced with the callsign of the station with whom a connection
is being attempted. The above example is based on a Kantronics KPC9612+ TNC.

Thanks a lot,

THE FASTRAC TEAM

『多くのアマチュア無線家が 12月10日の週末に、この衛星のデジピーターを多く
 使ってくれれば、電力を消費し、搭載CPU のハードリセットをすることが出来る
 ので、よろしく…』(拡大意訳) という意味だと思います。 つまり、今回のデジ
 ピーター ON は、電力を使い果たし、搭載CPU をハードリセットすることが目的
 のようです。そのことによって、「G」 だらけの Beacon が直るかもしれない…。

現在、1k2 と共に 9k6 も動作しています。(Observed by JH1BCL)

Up 145.825MHz / Down 437.345MHz, 1200bps
Up 145.980MHz / Down 437.345MHz, 9600bps

つまり、FAST1 の現在の周波数関係は次のとおりです。
