HuskySat-1 with VHF/UHF Linear Transponder Set to Deploy Soon

3 hours 37 min ago

The University of Washington’s HuskySat-1 3U CubeSat, launched November 2, 2019, is set to deploy on January 31 after the vehicle that carried it to the International Space Station undocks. HuskySat-1 has remained stowed aboard a Northrop Grumman Cygnus supply vehicle. Within 24 hours after Cygnus’ departure from the ISS, HuskySat-1 and SwampSat 2 will be deployed into orbit. After deployment, HuskySat-1’s 1,200 bps BPSK beacon on 435.800 MHz should be active and decodable with the latest release of AMSAT’s FoxTelem software. HuskySat-1 is expected to carry out its primary mission before being turned over to AMSAT for amateur radio operation.

HuskySat-1 features a 30 kHz wide V/U linear transponder for SSB and CW. The uplink passband will be 145.910 – 145.940 MHz LSB/CW. The downlink passband will be 435.840 – 435.810 MHz USB/CW (inverting). Telemetry will be transmitted on 435.800 MHz, 1k2 bps BPSK with an experimental downlink at 24.049 GHz. The “Fox-in-a-Box” FoxTelem software has been updated for HuskySat-1 operation at its download website. The new release now contains the SD card image, FIAB-distro8-V1.08w.zip. This file, when unzipped and written to a 16 GB SD card will provide the latest software for FoxTelem and will run on a Raspberry Pi 4. The 1.08 versions can switch bands between listening on VHF and UHF, based on which Fox and Husky satellites are overhead at the time.

 

(adsbygoogle = window.adsbygoogle || []).push({});

The linear transponder and telemetry system carried aboard AMSAT’s Fox-1E was designed for use in different CubeSats merely by adding an interface adapter for connection to the host bus. Noting the prevalence of CubeSats built and launched by universities and other organizations, AMSAT adopted a goal of “amateur radio in every CubeSat.” Interested CubeSat programs wanting to fly an amateur radio payload may partner with AMSAT to carry one of these modules on their spacecraft.

 

By providing amateur radio capability, the CubeSat program gets a worldwide ground station network to receive telemetry and experiment data, while the amateur radio community gets a transponder to use in orbit. Additional information is posted on the University of Washington Husky Satellite Lab siteThanks to AMSAT News Service via the HuskySat-1 Team, AMSAT Engineering, AMSAT Operations, the Fox Telemetry Team, and NASA

The K7RA Solar Update

Fri, 01/24/2020 - 13:40

No sunspots appeared over this reporting week (January 16-22) and on January 22 Spaceeweather.com reported currently the consecutive period of spotless days is 11. But all recent sunspots have had Cycle 25 polarity.

Average daily solar flux reported in last week’s bulletin was 72.5, and this week it was 71.2.

Average daily planetary A index went from 5.6 to 4.1, and the middle latitude A index changed from 3.7 to 3.

Predicted solar flux is 71 on January 24-31, 72 on February 1-5, 71 on February 6-20, 72 on February 21 to March 3, 71 on March 4, and 70 on March 5-8.

Predicted planetary A index is 5 on January 24-31, 10 on February 1-5, 5 on February 6-27, 10 on February 28 to March 3, and 5 on March 4-8.

Geomagnetic activity forecast for the period January 24-February 19, 2020 from F.K. Janda, OK1HH.

Geomagnetic field will be
quiet on: January 29-30, February 6-9, 13-16
quiet to unsettled on: January 24-28, February 1, 4-5, 10-11, 18-19
quiet to active on: (January 31, February 2-3, 12, 17)
unsettled to active on: no days
active to disturbed: no days

Solar wind will intensify on: January 24, February 2 (-3,) 6-7,
12-13, 18-19

Parenthesis means lower probability of activity enhancement.
The predictability of changes is lower again.

David Moore sent this article, “”Scientists measure the evolving energy of a solar flare’s explosive first minutes”: https://www.sciencedaily.com/releases/2020/01/200117122105.htm

The latest video from WX6SWW: https://bit.ly/2RY4HLZ

On January 21, G4KSG told me that two days earlier using a dipole at 30 feet he heard both sides of a EA3/JA7 QSO at 0900 UTC on 20 meters, but he did not specify the mode.

From Jeff, N8II: “Weather is very warm here after 4 inches of wet snow and 3 cold days this week, currently about 52 degrees F at 9 PM; 66 degrees tomorrow!

“I took down a 40-meter quad loop antenna today that performed poorly compared to my 80-meter dipole fed with ladder line. It took a while to remove all of the wire wrapped with stiff heavy wire at the insulators to prevent slippage and untie tight knots. I will put up a 40-meter dipole with higher average height.

“In the past month my band-slot totals have increased considerably, about 1950 slots since January 2017 as I recall counting the same country on CW and SSB on the same band as two slots. Very few DXpeditions were active, but activity and low-band conditions were good over the Christmas season. A UK group at ZC4UW in the British bases on Cyprus was active with over 25,000 contacts, but good for only 1 slot as ZC4A was on the air another year.”

When there are no sunspots, 160 meters seems to improve, probably because of lower associated geomagnetic activity. In fact, geomagnetic activity is recently nearly non-existent. This weekend is the CQ World-Wide 160-meter CW contest. See details at https://www.cq160.com/rules.htm

Note the low geo-activity toward the end of 2019:

Estimated planetary A indices were 5, 3, 4, 3, 2, 6, and 6, with a mean of 4.1. Middle latitude A index was 4, 2, 3, 2, 2, 4, and 4, with a mean of 3.

ARRL to Argue for Continued Access to 3-GHz Spectrum as FCC Sets Comment Deadlines

Fri, 01/24/2020 - 13:00

At its January meeting, the ARRL Board of Directors instructed the League’s FCC counsel to prepare a strong response to protect amateur access to spectrum in the 3 GHz range. In its Notice of Proposed Rulemaking (NPRM) in WT Docket 19-348, the FCC proposed to relocate all non-federal operations, including amateur uses, to spectrum outside the 3.3 – 3.55 GHz band. The Commission anticipates auctioning this spectrum to expand commercial use of 5G cellular and wireless broadband services, if agreement can be reached on relocation of — or sharing with — the federal incumbents that operate in the same band. Publication of the NPRM in the Federal Register on January 22 established deadlines of February 21 for comments and March 23 for reply comments.

The FCC has requested comment on the uses radio amateurs make of the spectrum and appropriate relocation options. Complicating matters is the fact that radio amateurs must consider the possibility that the immediately adjacent 3.1 – 3.3 GHz band is included in the spectrum that Congress has identified for similar study. FCC Commissioner Michael O’Rielly, in a December statement, referenced the fact that the lower band may also be considered for non-federal reallocation, potentially limiting relocation possibilities.

Amateurs make substantial use of the 3.3 – 3.5 GHz band that would be hard to replicate elsewhere, and they have filed more than 150 comments before the designated comment period even began. Among users looking at options are those who use this spectrum for Earth-Moon-Earth (moonbounce) communication, mesh networks, experiments with communication over long distances, radiosport, and amateur television. A portion of the band also is designated for use by amateur satellites in ITU Regions 2 and 3 (the Americas and Asia/Pacific).

A report is due by March 23 from the National Telecommunications and Information Administration (NTIA) evaluating the feasibility of having federal users share all or part of the 3.1 – 3.55 GHz band with commercial wireless services. This report is required by the Making Opportunities for Broadband Investment and Limiting Excessive and Needless Obstacles to Wireless (MOBILE NOW) Act. The results of the NTIA report will impact how much spectrum ultimately may be re-allocated for auction to wireless providers.

ARRL urges amateurs who comment to inform the FCC about the uses they make of the 3 GHz spectrum. Short comments and longer statements may be filed electronically. Visit the FCC “How to Comment on FCC Proceedings” page for more information. Commenters should reference WT Docket 19-348.
