Launch Window for AMSAT's RadFxSat-2/Fox-1E Opens December 19, 2020
Virgin Orbit has announced that the launch window for their LauncherOne Launch Demo 2 mission opens on December 19 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

FoxTelem 1 09 Released
Chris Thompson, G0KLA/AC2CZ announced the availability of FoxTelem 1 09 This release provides several enhancements and needed changes for RadFxSat-2/FOX-1E This new spacecraft sends 1200bps BPSK telemetry in parallel with a linear transponder Downloading telemetry and sending it to the server will assist AMSAT and the Radiation tolerance experiments from Vanderbilt University
You can download FoxTelem 1 09 at: http://amsat us/FoxTelem/windows/FoxTelem_1 09n3_windows zip http://amsat us/FoxTelem/linux/FoxTelem_1 09n3_linux tar gz http://amsat us/FoxTelem/mac/FoxTelem_1 09n3_mac tar gz
The changes from 1 08 to 1 09 are as follows: * Performance improvements on the telemetry tabs This uses less CPU than 1 08 * Clearer display of historical records on the telemetry tabs for RT, MAX, MIN and WOD * Bug fixes for Fox-1E decode and display of diagnostic tables, Whole Orbit Data, and formatting of telemetry * Ignore extra commas in conversion curve comments * Allow a single spacecraft to be downloaded from the Fox Server, even if FoxTelem stores many spacecraft * Latest Golf-T layouts for development * BPSK CRC checksum calculation for GOLF-T * Another new way to decode and display the mode * More generic tab layouts to allow future expansion through soft coding * Throttle the DDE requests when decoder stopped * Many other bug fixes
See the complete list on github at: https://tinyurl com/ANS-341-FoxTelem
On Saturday, December 5, 2020, Chris added the following information:
"If you are having difficulty upgrading to FoxTelem 1 09 because it says that it can not write some files, then I have put together a procedure to migrate your data If in frustration you reset the FoxTelem properties file and now you don't have your old telemetry from 1 08, then this will still likely work and recover the data Details are at: https://www g0kla com/foxtelem/tutorial_moving_foxtelem_logfiles php
"Many thanks to Frank K6FW who helped work out this procedure Feel free to reach out to me for help "
Burns Fisher, WB1FJ adds, "For those of you with Fox-In-A-Box telemetry stations (Fun Cube Dongle in a Raspberry Pi with FoxTelem software), FoxTelem 1 09 has been successfully tested on an FIAB
"It is easy to update your FIAB with the new FoxTelem version Some time ago, I provided the instructions for upgrading to a new FoxTelem and they will not have changed significantly other than the version numbers You can view the instructions at: https://tinyurl com/ANS-341-FIAB-Upgrade
"In any case, over the next few days, I will update and post the instructions as well as making the new version available on the FIAB SD cards sold in the AMSAT store and (a bit after that) on the free download "

IARU Coordinates Frequencies for Three Satellites in November
During the month of November the IARU coordinated frequencies for three upcoming Amateur Radio satellites:
All of the code that the satellite and ground station runs will be open source and published to Github (except telecommand encryption) allowing Amateurs to use the knowledge and code for their own projects The UHF downlink uses 9k6 2GSK with AX25 Planning a CSLI deployment from the ISS in Q1 2022 A downlink on 437 365 MHz has been coordinated More info at http://gas usu edu and https://tinyurl com/ANS-341-GASPACS
The link to the Github documentation can be found at: github com/SmallSatGasTeam/CubeWorks
SMOG-2 SMOG-2 is a 3p PocketQube continuation of SMOG-P and SMOG-1 spectrum monitoring pocketqube class satellites with wider monitored spectrum range focused on HAM, ISM and broadcasting bands Worldwide Amateur Radio stations can receive its spectrum monitoring data to help create a global electromagnetic pollution map to be published at http://gnd bme hu The UHF downlink uses 5kb GMSK Planning a RocketLab launch from New Zealand into a 600 km SSO in 2021 A downlink on 437 150 MHz has been coordinated
D3 The mission is a 2U CubeSat intended to demonstrate the performance of a novel drag-based targeted point re-entry algorithm using repeatedly deployable/retractable drag surfaces to perform orbital maneuvers that guarantee spacecraft re-entry at a pre-defined location If successful, the D3 module can be adapted to other Amateur Radio satellites to ensure consistent re-entry and help reduce the concentration of space debris The mission is run solely by Amateurs with the purpose of helping future Amateur missions The UHF downlink uses 9k6 GMSK downlink for AX25 telemetry and data and 1k2 AFSK for a beacon Planning a launch to the ISS in September 2021 Downlinks on 437 080 MHz and 2432 000 MHz have been coordinated More info from http://adamus-d3-website herokuapp com/

Orbital Mechanics for Dummies
Orbital Mechanics has been around since well before artificial satellites were even remotely possible (Remember that Johannes Kepler who gave us Keplerian elements we use in tracking satellites today published his book, The Cosmographic Mystery, in 1596! And Walter Hohmann first described transfer orbits in 1929
Rendezvousing with another object in the same orbit is perhaps the most counterintuitive, as you must adjust your orbital period by leaving the shared orbit and later re-entering it To "slow down" you accelerate to increase the height of your orbit, lengthening your orbital period relative to the other craft, let time pass, and then re-enter the original orbit once they've caught up Conversely, to catch up, you decrease velocity to achieve a smaller, more eccentric orbit, which has a shorter orbital period
There are tons of resources out there for diving into the math of orbital mechanics Surprisingly, one of the easiest to read comes from the FAA's Office of Aerospace Medicine as part of their "Advanced Aerospace Medicine On-line" course at: https://bit ly/3oaOSzM
You can also play with orbits in a simulator at: https://orbitalmechanics info/
Or, if you really want to develop a more intuitive sense of two-body orbital mechanics while having a blast (pun very much intended), play the Kerbal Space Program (not a free game) at: https://www kerbalspaceprogram com/game/kerbal-space-program/

Brandmeister DMR Network Announces Password Implementation
The AMSAT DMR talkgroup is 98006 on the Brandmeister Network Walter Holmes, K5WH, has received notice of changes coming to Brandmeister from the network administrators:
"Due to issues that have been happening recently, we are going to need to start requiring users to set a hotspot security pass-word to gain access to the US Masters If you already have a hot spot security password set on the BM portal, you can ignore this post We are going to start requiring this on master these US master servers:
"This is already implemented on the RU masters, and other Master Servers will follow At this time this will just be for hotspots The API is being worked on to allow repeater owners to make this change as well, but it is not quite ready to go "
Walter noted, "Since we all use the US DMR Master servers, 3101, 3102, or 3103, they will be changed starting as early as December 1, 2020, requiring a HotSpot PASSWORD be set, or you will no longer be able to use DMR Whether you have a Hotspot, BlueDV, DudeStar, DroidStar, or ANY of the other applications to access DMR, these change is required "
Be sure to log into the Brandmeister site, and create an account right away if you don't already have one, as it may take a few days to get that authorized: https://brandmeister network/
For instructions on how to set your hotspot security on the Brandmeister portal visit https://tinyurl com/ANS-341-DMR
In conclusion Walter said, "If you're not comfortable with these steps, help is available via a Zoom channel Reach me at k5wh@k5wh net for the link "
