ISS SSTV MAI-75 image 9/12 received by Chertsey Radio Club on Baofeng handheld

Russian cosmonauts are expected to activate Slow Scan Television (SSTV) image transmissions on 145.800 MHz FM from the International Space Station on Wednesday to Friday, December 4, 5 and 6.

This is the schedule for the planned activation of the MAI-75 SSTV activity from the ISS.
• Dec 4: On – 12:00 GMT, Off – 16:50 GMT
• Dec 5: On – 11:25 GMT, Off – 17:15 GMT
• Dec 6: On – 10:20 GMT, Off – 16:40 GMT

Transmissions will be sent on 145.800 MHz FM (5 kHz deviation) in the SSTV mode PD-120. Once received, images can be posted and viewed by the public at http://www.spaceflightsoftware.com/ARISS_SSTV/index.php

ISS SSTV uses a Kenwood TM D710E transceiver which is part of the amateur radio station located in the Russian ISS Service Module.

Please note that SSTV events are dependent on other activities, schedules and crew responsibilities on the ISS and subject to change at any time. You can check for updates regarding planned operation at:

An FCC Notice of Proposed Rulemaking (NPRM) proposes to remove the existing non-federal allocations in the 3.3-3.55 GHz band.

The FCC say:

By taking the initial step needed to clear the band of allocations for non-federal incumbents, the Commission furthers its continued efforts to make more mid-band spectrum potentially available to support next generation wireless networks—consistent with the mandate of the MOBILE NOW Act.

What the NPRM Would Do:

• Propose to clear the 3.3-3.55 GHz band of existing non-federal users by removing the non-federal secondary radiolocation and amateur allocations in the 3.3-3.55 GHz band;
• Propose to relocate incumbent non-federal users out of the band;
• Seek comment on relocation options and transition mechanisms for incumbent non-federal users, either to the 3.1-3.3 GHz band or to other frequencies;
• Seek comment on how to ensure that non-federal secondary operations in the 3.1-3.3 GHz band will continue to protect federal radar systems; and
• Prepare the band for possible future shared use between commercial wireless services and federal incumbents, potentially making as much as 250 megahertz of spectrum available for flexible use, including 5G.

Regarding the Amateur and Amateur-Satellite Service allocation they say:

12. With respect to amateur operations, is there sufficient existing amateur spectrum in other bands that can support the operations currently conducted in the 3.3-3.5 GHz band? We note that the 3.40-3.41 GHz segment is designated for communications to and from amateur satellites. We seek comment on: the extent to which the band is used for this purpose, whether existing satellites can operate on other amateur satellite bands, and on an appropriate timeframe for terminating these operations in this band.

In the final week meetings at WRC-19 have been running until 3am in the morning in an attempt to get the work completed.

The RSGB have released their WRC-19 report covering small satellites and also the Amateur 1240-1300 MHz band.

The report notes “A lesson from the process indicates how difficult it may be in future to achieve any upgrade to other amateur allocations.”

The IARU has issued its report on Week 3 of the 2019 World Radiocommunication Conference being held in Sharm el-Sheikh, Egypt from October 28 to November 22, 2019.

With just 3-1/2 days left for substantive work – the final session of the Plenary to approve texts to be included in the Final Acts is scheduled to end at noon Thursday, November 21 – delegates at WRC-19 face a daunting workload as the conferees try to reach consensus on several remaining issues including the agenda for the next WRC.

Future agenda items: As of now, no choices have been made as to which of more than three dozen proposed topics will be placed on the WRC-23 agenda. Each of the proposed agenda items would require studies to be conducted in the 2020-2023 timeframe, but ITU resources will not accommodate more than about half. Some face strong opposition and others remain ill-defined even at this late stage of the conference. The responsible committee is scheduled to complete its work in just one more day. It will be a long day.

Short Duration Satellites: There is still no agreement on how to protect existing services and uses of the uplink frequency band proposed for telemetry, tracking and command of these “simple” satellites.

5725-5850 MHz: This part of the amateur secondary allocation, which includes an amateur-satellite downlink at 5830-5850 MHz, is the subject of an unresolved conflict over parameters for wireless access systems including radio local area networks.

Frequencies above 275 GHz: This upper frequency range is not allocated but several bands are identified for passive (receive-only) use and administrations are encouraged to protect them from harmful interference. With that in mind, WRC-19 has identified other bands above 275 GHz for the implementation of land mobile and fixed service applications. The use of these bands for applications in other services, including amateur experimentation, is not precluded.

50 MHz in Region 1: The compromise agreement reported last week (see the IARU news release dated 10 November) survived review at the Working Group and Committee levels and awaits approval in Plenary.

With the 50 MHz issue essentially settled the IARU team is devoting most of its energy to explaining why the proposed agenda item for 1240-1300 MHz described in last week’s release is unnecessary and undesirable.

While IARU President Tim Ellam, VE6SH/G4HUA, left the conference at the end of the second week he is still a visible presence as a six-minute video interview is replayed on monitors scattered around the halls of the conference center. See it for yourself at
