If you look at my screenshot you can see I was receiving on 1485.966+ 916 IF downconverter=2401.97 MHz, consider than doppler shift and downconverter error and you are around the nominal frequency of 2401.843 Mhz. The others screenshot with telemetry analysis where coming from cw beacon signal. Mission is ended but you can find cw telemetry beacon decoder algorithm here:http://www.ne.jp/asahi/hamradio/je9pel/dtusat_1.htm Have fun with DTUsat-2Fer IW1DTU On Saturday, June 10, 2017 10:58 AM, Perry Yantis <py41(a)att.net> wrote: Thanks for the information.I have uplink at 1268.900, downlink at 2401.835, and beacon at 2401.843.I have listened up and down the frequency and have not heard anything.I may have a problem with the down converters but no way to test that.That is why I have listened for it.I see on one of the pictures you sent that you were listening to 2401.858.I will try again today around noon when I have an overhead pass.Also I do not have the decoding program that you have so I was wondering what you are hearing, I am guessing a data signal???

Automatic GS Tracking Satellites Software
by Tanan Rangseeprom 09 Jun '17

09 Jun '17

Dear friend or member of AMSAT, The Radio Amateur Society of Thailand under the patronage of His Majesty the King (RAST) has received support and funding for the JAISAT-1 project from Thailand's regulator, the National Broadcasting and Telecommunications Commission from its Fund for the Research and Development of Broadcasting, Television and Telecommunications for Public Benefit - BTFP. Construction of the Linear Transponder has been completed and this module is now in the process of construction and assembly by Innovative Solutions in Space (ISIS) in the Netherlands. The society has also received permission from the NBTC to set up a Ground Station (GS) with the callsign HS0AJ together with funding to purchase an Icom IC-9100 transceiver, a G5500 rotor together with computer equipment to be used at the GS HS0AJ and this has now been set up and completed. However, we have encountered problems in finding an appropriate program for automatic tracking of the satellite. We have installed the Ham Radio Deluxe program on the Windows 10 operating system on the computer but we have encountered many problems such as the IC-9100 driver being unable to communicate with the computer while the Ham Radio Deluxe program has been unable to control or send commands to the Fox Delta Antenna Rotor Control. The primary purpose of the HS0AJ ground station is to track all amateur radio satellites that pass over Thailand in all modes by setting up a tracking schedule plan for automatic tracking on a daily or weekly basis. Our goal is to forward the audio of satellite signals from the Icom IC-9100 as they pass over Thailand to the RAST website to enable Thai amateur radio operators to monitor these signals online in RAST website and Echolink program. RAST would like to seek advice from our AMSAT friends worldwide regarding any recommendations of a automated satellite tracking program suitable for the objectives of our ground station. Thanking you in advance and with respect, Tanan Rangseeprom, JAISAT Project Manager

AO73 Mode change
by Graham Shirville 09 Jun '17

09 Jun '17

Hi folks, AO73/FUNcube-1 is now in amateur mode for an extended weekend with the transponder on to enable demonstration QSOs to take place in sunny Dayton - have FUN everyone! 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. _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

A while back AMSAT-UK issued certificates/QSL cards to folks who downloaded telemetry from AO-73. Does anyone know if there is a corresponding certificate/QSL for EO-88? I couldn't find any info about this on the AMSAT-UK website. (Yes, I do collect wallpaper.) Steve AI9IN
