Telemetry

ITASAT-1 telemetry 2020-12-04

Strong telemetry at 145.858 MHz easy to decode. Used the following:

  • RX at aprox 145.858 MHz USB BW 3.2 kHz
  • 2 * 6 el Yagi circular polarization (Vårgårda)
  • AlfaSpid RAS az/el rotor
  • LNA Mini-2 from SHF Elektronik
  • LMR-400 coax
  • SDR Airspy Mini
  • SDR-Console v3 with doppler correction of downlink and satellite tracking, rotor control
  • PstRotator for rotor control interface between SDR-Console and RAS controller
  • VB-Cable: virtual audio cable for piping audio from SDR Console to Soundmodem. Set to 96 kHz and 16 bit.
  • Soundmodem v 1.05 at mode BPSK AX.25 1200bd (1k2). Be sure that the BPSK signal is centered “over” the signal in the spectrum. See image.
  • Telemetry reader and forwarder from DK3WN, in order to see and forward telemetry to SatNOGS. Note that this is a beta version.

RadFxSat-2 / Fox-1E uppskjutning 19 december 2020

Den sista satelliten i AMSAT-NAs FOX-serie, RadFxSat-2 / Fox-1E, har fått ett uppskjutningsfönster som börjar den 19 december (2020). Till skillnad mot de andra FOX-satelliterna, som har haft FM-transponder, har Fox-1E en linjär inverterande transponder för SSB och CW-trafik.

Dessutom har telemetrilänken flyttat till 70cm på 435.750 MHz och kan tas emot med den senaste versionen av FoxTelem.

Launch Window for AMSAT’s RadFxSat-2 / Fox-1E Opens December 19th

Virgin Orbit has announced that the launch window for their
LauncherOne Launch Demo 2 mission opens on December 19th. This launch
will carry AMSAT’s RadFxSat-2 / Fox-1E to orbit.

RadFxSat-2, like RadFxSat / Fox-1B, now AMSAT-OSCAR 91, is a
partnership opportunity between Vanderbilt University and AMSAT and
will carry a similar radiation effects experiment, studying new FinFET
technology.

RadFxSat-2 is the fifth and final Fox-1 satellite built by AMSAT. The
RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a
linear transponder “upgrade” to replace the standard FM transponder in
Fox-1A through D. In addition, the uplink and downlink bands are
reversed from the previous Fox satellites in a Mode V/u (J)
configuration using a 2 meter uplink and 70 cm downlink. The downlink
features a 1200 bps BPSK telemetry channel to carry the Vanderbilt
science data in addition to a 30 kHz wide transponder for amateur
radio use. Telemetry and experiment data can be decoded using FoxTelem
version 1.09 or later. FoxTelem is available at
https://www.amsat.org/foxtelem-software-for-windows-mac-linux/.

Participation in telemetry collection by as many stations in as many
parts of the world as possible is essential as AMSAT Engineering looks
for successful startup and indications of the general health and
function of the satellite as it begins to acclimate to space. AMSAT
will send a commemorative 3D printed QSL card to the first station
capturing telemetry from RadFxSat-2.

RadFxSat-2 / Fox-1E Frequencies:

Telemetry Downlink – 435.750 MHz
Inverting Linear Transponder Uplink – 145.860 MHz – 145.890 MHz
Inverting Linear Transponder Downlink – 435.760 MHz – 435.790 MHz

Utlottning av Bullseye LNB – årets julklapp 2020!

Dags för en ny “give-away” från AMSAT-SM! Nu lottar vi ut en Othernet Bullseye LNB, en extra frekvensstabil LNB för Oscar 100. Årets julklapp 2020 för oss i AMSAT. Läs mer om den här:
https://www.passion-radio.com/lnb-pll/lnb-othernet-978.html

Det är mycket hög chans att vinna så det finns ingen anledning att inte deltaga. Detta är reglerna

  • Du måste vara medlem i AMSAT-SM (vilket är kostnadsfritt och kan göras här)
  • Sista dag för att deltaga är söndag 13 december 2020
  • Om du vinner kommer du få LNB levererad direkt hem så det är viktigt att dina adressuppgifter är korrekta
  • Observera att det inte är en komplett mottagare, du måste själv bygga ihop en lösning.

Satellite Memory File for IC-705

This is a memory group file over satellite frequencies for Icom IC-705 and CS-705 software. It is not complete and will be updated. Feel free to use it, change and add, make your own groups etc.

The memories are used like this:

  • Channels named with satellite name, for exemple “PO-101 Split”, are used in split mode. This channel can be used when using the IC-705 for portable operation or without an extra receiver .
  • The FM-satellites also has five split memories each with AOS-LOS frequencies – for portable operation without computer doppler tuning.
  • Channels named with satellite name and Uplink, for exemple “PO-101 Uplink”, are used only for uplink (not split). This can be used with software like SDR-Console v3 (external radio) or if you have an extra receiver.
  • Channels named with satellite name and Downlink, for exemple “RS-44 Downlink”, are used only for downlink (not split).

Import the memory file into CS-705:
Note! Be sure that you not overwrite anything in your IC-705 when cloning. Make a backup of your current settings!

  • Create a new memory group
  • Mark this new group
  • Choose File->Import->Group and choose the .csv file
  • The memories will now be imported to CS-705
  • Clone to your IC-705

As CS-705 seems to handle character set different between regions I have now created two files. If one does not work, try the other one. Comma separated is working for North America.

Download the latest files from SM0TGUs Github:
IC-705_SatFrqMemGroup.csv
IC-705_SatFrqMemGroup_commaseparated.csv

The files has to be downloaded as a zip file from GitHub, then use your file of interest:

If you have problems downloading the files from GitHub please contact us and the files can be sent via mail.

RT Systems Memories example

The following explanation is from Jack Spitznagel – KD4IZ, for the RT Systems software.This brief explanation assumes that the RT Systems IC-705 Programmer user knows how to import memories into the software:

  1. Before you merge these into an existing RT Systems memory set, it is first necessary to open the .CSV file in a spreadsheet (Excel or Libre Office) and edit the Channel Number and Bank names. Save the edited file as a .CSV file.
  2. Channel numbers should be set to start numbering at the first open memory row (this example: if row 77 is your first open memory row, start numbering at 77, go up to 99).
  3. Bank numbers should be changed to the first open memory Bank # in the form “##:Bank Name”. In the example, “04:Satellite” was used because Bank 0, 1, 2, and 3 already have assigned names in the memopry file that was used. Interestingly, the “Satellite” Bank Name was not recorded which requires some easy editing of the new file.
  4. Save your RT Systems memory file to a NEW FILENAME so you don’t lose your settings. Users may want to edit the arrangement once the data is imported into the RT Systems IC-705 Programmer.
