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.

Hi folks,
I am looking for a good program like Orbitron or the old Satsked that gives me the possibility to keep under the eyes all the satellite and in the mean time has the possibility to track the satellites moving also the rotators and the radio.I was using SatPC interfaced with the rotators with the ERC-M kit and the Kenwood TS-2000x. It is a great program but has the problem that I do not have under my eyes all the satellites and have noticed that if I am visualising in one group and in another group there is a satellite rising I will not be advised.
Orbitron is OK as I can have all the satellites under my eyes but I cannot or better I do not know how to interface it with the radio and the Yaesu G-5500 rotators via the ERC-M interface kit.
Anybody can point me to the right way?
Thanks

The Chinese amateur satellite Zhou Enlai (initially know as Huai'An 1,
HA 1) appears to be active on a downlink frequency near 437.650 MHz.
Its coordinated downlink frequency for telemetry is 437.350 MHz and
for voice 436.950 MHz. For details see:
http://www.amsat.org.uk/iaru/http://space.skyrocket.de/doc_sdat/zhou_enlai.htm
This 2U cubesat is object 43156, 2018-008B. Let's see if they can activate
its FM repeater and SSTV component.

Hi Jim,
I use XMLOG...have for years...All I enter is the date and time...the
call...the xmit freq either 145 or 435...the mode..always FM hi
hi...power...and satellite name...CTRL-F populates the grid of the station
you worked once you tell XMLOG where to look; I use QRZ.com.
Thanks for the dxpedition and good luck logging it!

International Space Station Astronauts are Calling CQ Students (corrected)
ARISS-US program education proposal deadline is April 30, 2018
March 15, 2018: The Amateur Radio on the International Space Station (ARISS) program is seeking proposals from US schools, museums, science centers and community youth organizations (working individually or together) to host radio contacts with an orbiting crew member aboard the International Space Station (ISS) between January 1 and June 30, 2019.
Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, “ARISS shows how Amateur Radio is the most unique hobby/service there is.”
Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, “It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!” Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, “This chance for our school’s ARISS contact helped me see the great value of the ham world. I just passed my Technician License this weekend and have already signed up to take a General class.”
ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students.
The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary. To sign up, go to https://ariss-proposal-webinar-spring-2018.eventbrite.com
