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

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.

Uplink LSB 145.860 MHz through 145.890 MHz
Downlink USB 435.760 MHz through 435.790 MHz
Launches on ELaNa XX – Virgin Orbit LauncherOne Launch Demo 2. 1.2kbps BPSK telemetry 435.750 MHz


Free Digital Copy of “Getting Started with Amateur Satellites” Now Available for New or Renewing Members

The University of Washington’s HuskySat-1 CubeSat is scheduled to be deployed from the Cygnus NG-12 spacecraft at 22:30 UTC today. HuskySat-1 carries an AMSAT VHF/UHF linear transponder that will be made available for amateur use following its primary mission to test a pulsed plasma thruster and experimental K band (24 GHz) communications system.

While the satellite completes it’s scientific mission, check out the best resource for learning how to work through linear transponder satellites (and other types of amateur satellites). For a limited time, AMSAT is making the “Getting Started With Amateur Satellites” book available as a download with any paid new or renewal membership purchased via the AMSAT Store. This offer is only available with purchases completed online, and for only a limited time. A perennial favorite, Getting Started is updated every year with the latest amateur satellite information, and is the premier primer of satellite operation. The book is presented in PDF format, in full color, and covers all aspects of making your first contacts on a ham radio satellite.

Please take advantage of this offer today by visiting the AMSAT store at and selecting any membership option. While there, check out AMSAT’s other items, including the M2 LEOpack antenna system, Arrow antennas, AMSAT shirts, and other swag. Be sure to view your cart before going to checkout. If you add a membership and then go directly to checkout, you’ll never see an option to add your free gift.


CAMSAT CAS-6 Satellite to Launch December 20th

CAMSAT’s CAS-6 satellite is scheduled to launch at 03:21 UTC on December 20, 2019. CAS-6 is a payload on the technology test satellite Tianqin-1, which will launch on a CZ-4B launch vehicle from Taiyuan Satellite Launch Center. The primary payload on this launch is the China-Brazil Earth Resources Satellite (CBERS-4A).

CAS-6 will be launched to a sun-synchronous orbit at 629 km with an inclination of 97.89 degrees. The satellite carries a 20 kHz wide U/v linear transponder with an uplink of 435.270 MHz –  435.290 MHz and a downlink of 145.915 MHz – 145.935 MHz. The satellite also carries a CW telemetry beacon at 145.910 MHz and a 4k8 GMSK telemetry downlink at 145.890 MHz.

Telemetry downlink specifications and further technical information can be found in the following documents:

SMOG-P and ATL-1 Designated Magyar-OSCAR 105 (MO-105) and Magyar-OSCAR 106 (MO-106)

On December 6, 2019, the Technical University of Budapest SMOG-P and ATL-1 PocketQubes were launched on an Electron launch vehicle from the Mahia Launch Complex in New Zealand. SMOG-P and ATL-1 were developed as part of the university curriculum and operated in cooperation with the HA5MRC Technical University amateur radio club. The satellites carry spectrum monitoring payloads and are currently active.

At the request of the Technical University of Budapest, AMSAT hereby designates SMOG-P as Magyar-OSCAR 105 (MO-105), and ATL-1 as Magyar-OSCAR 106 (MO-106). We congratulate the owners and operators, thank them for their contribution to the amateur satellite community, and wish them a long mission and continued success on this and future projects.
