The program can easily detect and fix the TLE preliminary data errors
for working in satellite programs after launching the satellite in orbit
The original version of the program released before launching Fox-1D
works in Windows-7 and higher. Version that works in Windows XP is now
added. The program name for Win-XP changes to TLEdoctor.
Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php

Hi folks,
AO73/FUNcube is now in amateur mode for the weekend with the transponder on!
Please see below for all FUNcube mission info
73s Graham G3VZV and the FUNcube team.
++++++++++++++++++++++++++++++++++
FUNcube frequencies and other details
++++++++++++++++++++++++++++++++++
AO-73 FUNcube-1
The transponder is normally operational only when the satellite is in
eclipse, ie the solar panels are NOT being illuminated. During weekends
(from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power. During holidays,
eg Christmas, New Year, Easter, etc, the transponder maybe activated for
extended periods. Watch AMSAT-BB for announcements which are usually made on
Friday evenings (UTC)
The nominal transponder frequencies are:
Uplink: 435.150 - 435.130 MHz LSB (Inverting)
Downlink: 145.950 - 145.970 MHz USB
Telemetry Tx: 145.935 MHz BPSK
(The passband may be up to 15kHz higher depending on on-board temps. Lower
temperatures give higher freqs!)
FUNcube-2 (aka FUNcube on UKube)
The FUNcube-2 sub-system continues to operate autonomously and, almost
continuously, in amateur mode. The transponder is operational and the
telemetry downlink is functioning with about 70mW output. The FUNcube-1
Dashboard does not correctly display the telemetry but it does correctly
decode the data and uploads it to the FUNcube Data Warehouse from where it
can be examined. Most of the real time data channels are operational and
these include battery voltages, temperatures and ADCS data coming via the
main On Board Computer (OBC).
The transponder is interrupted for a few seconds every 2 minutes when the
other transmitter sends its CW beacon and, occasionally, for a few seconds
when the main OBC reboots (approx seven times each orbit).
The nominal transponder frequencies are:
Uplink: 435.080 - 435.060 MHz LSB (Inverting)
Downlink: 145.930 - 145.950 MHz USB
Telemetry Tx: 145.915 MHz BPSK
(The passband may be up to 10kHz higher depending on on-board temps. Low
temperatures give higher freqs!)
EO79 FUNcube-3
Due to power budget constraints the transponder cannot be operational 24/7
and an orbit specific schedule has been developed. The transponder will
commence operation 27 minutes after the spacecraft enters sunlight and will
stay on for a period of 25 minutes. This schedule may be modified in future
months as a result of experience.
The nominal transponder frequencies are:
Uplink: 435.0723-435.0473 MHz LSB (Inverting)
Downlink: 145.946-145.971 MHz USB
Further detailed info on EO79 transponder frequencies is at:
https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula…
EO88/Nayif-1/FUNcube-5
EO88 is presently operating in autonomous mode. The transponder is
operational when the satellite is in eclipse, ie the solar panels are NOT
being illuminated.
When the transponder is switched off, the telemetry beacon is on full power,
when the transponder is on the beacon it is on low power.
The transponder frequencies are:
Uplink: 435.045 – 435.015 MHz LSB (inverting)
Downlink: 145.960-145.990 MHz USB
Telemetry Tx: 145.940MHz
All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very
grateful for the assistance given by Innovative Solution In Space Bv, The
Netherlands.

Hi All,Just to confirm that AO73 is now in continuous education mode with the high power telemetry. Amateur mode may be expected to resume on Thursday morning(UTC)73GrahamG3VZV
Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Thinking about adding the 1.2Ghz module for my 9100. Prices have dropped a little and units will start become harder to find once production ends. Anybody using this band? I read it's used as a uplink frequency for some satellites. Any input appreciated.ToddAL7PX
The Outernet L-band feed is now carrying a condensed version of the AMSAT
and ARISS weekly news files. (Global Geosat coverage except for Northern
Alaska)...
Receivers are simple: http://aprs.org/outnet.html
For ARISS, I manually added a 2 char grid square to each school listed in
the school schedule and am asking the outernet folks to parse out that
location info and plot a 1200 km footprint on their weather globe showing
where people can tune in the ARISS contacts. Then their RTL-SDR dongle
could then actually be retuned to hear the contact. Just an idea...

Does anyone have any information about the Dstar satellite D-Star One
Pheonix that German Orbital Systems built and launched.
Would appreciate any info
Thanks

Be the first on your block to receive the new AMSAT Award. Yes, after
many years, AMSAT has a new award. Visit http://www.amsat.org
click on Services, then Awards and then the very first award on the top
(hint... it is the new one)
I have not had a chance to work up the submission sheet for it. I will
do that soon. It will make it easier to submit and check the award.
Thanks to those that gave input and guidance for the award.

Hello ListI have been having trouble getting going with full doppler tuning with satpc32 and the ts2000 , I have the port and baud set.the most I have got it the radio to do is make a chirp-beep sound and sometimes the incorrect bands will load into the vfo'swhen I click on the birds A,B,C,D etc , but I can not seem to get it to tune the correct frequency's or start to tunethe vfo as the sat flys over... perhaps i need something more in the *.sql data files ??All the signals I have heard so far are very weak , Im guessing I going to need a good preamp and would also like feedbackon ready to install preamps and antenna's you like.please delete the original messages in your reply or go direct off list...jhill_81(a)yahoo.com
