AMSAT News Service Bulletin 245 01
From AMSAT HQ KENSINGTON, MD September 2, 2018 To All RADIO AMATEURS BID: $ANS-245 01
DMR Station QRM's AO-92 Uplink
On August 27th, AMSAT Vice President-Operations Drew Glasbrenner, KO4MA, noted:
"Recently there has been a DMR signal QRM'ing the AO-92 uplink on 435 350 or close by Hotspots, repeaters, terrestrial simplex (anything not satellite) should not be in 145 8-146 0 or 435-438 by international bandplan Please QSY these radios ASAP Please share to DMR, D-star, Fusion, P25 groups and similar, thank you!"
For amateur operators in the U S , FCC Part 97 has a bit to say about the way we should operate in the 145 8-146 0 and 435-438 MHz amateur satellite subbands Regulations in many other countries are not as detailed as those established by the FCC on how we should operate on different frequencies and bands This includes where hotspots and similar systems used for digital voice modes (i e , DMR, D-Star, C4FM/Fusion) and other technologies like EchoLink and IRLP, should operate
Auxiliary stations are defined at 97 3(a)(7):
"An amateur station, other than in a message forwarding system, that is transmitting communications point-to-point within a system of cooperating amateur stations "
This definition includes "remote bases;" the nodes for systems like EchoLink and IRLP; and hotspots used for digital-voice modes like D- Star, DMR, and Fusion/C4FM (among others); as well as stations using these hotspots and nodes Auxiliary stations are not allowed in the 145 8-146 0 and 435-438 MHz satellite subbands per 97 201(b) - among other subbands in the 2m and 70cm amateur bands
Repeaters are defined at 97 3(a)(40) as:
"Repeater An amateur station that simultaneously retransmits the transmission of another amateur station on a different channel or channels "
Since most hotspots are operating on a single frequency, they would not qualify as a repeater Even if the hotspot operates like a repeater as defined above, repeaters are not permitted to use 145 5-146 0 MHz and 435-438 MHz per 97 205(b)
Beyond these two sections, Part 97 also has 97 101(a): "In all respects not specifically covered by FCC Rules each amateur station must be operated in accordance with good engineering and good amateur practice "
Whether the hotspot is interfering with a satellite downlink in a particular area, or it is interfering with the satellite uplink affecting a much larger area, this would not be good amateur practice
In addition to subbands where hotspots are not permitted, 97 101(b) is also relevant:
"Each station licensee and each control operator must cooperate in selecting transmitting channels and in making the most effective use of the amateur service frequencies No frequency will be assigned for the exclusive use of any station "
Frequencies used by satellites are usually incapable of being changed, and have been registered with a regulator like the FCC and the ITU Hotspots are usually frequency-agile, and the frequencies used by those systems can be changed to avoid potential interference to satellites and other stations
And all of this is in addition to local bandplans, which may already have provisions for hotspots or simplex nodes

AO73/FUNcube-1 Entering a Further Period of Full Sunlight
AO73/FUNcube-1 has been in space for almost five years and the original Sun Synchronous Orbit has now changed slightly such that the spacecraft will no longer be in eclipse for 35 mins every orbit
The eclipse period has already reduced and will again become zero on September 8, 2018 This means that our usual autonomous switching between transponder on in eclipse and high-power telemetry when in sunlight will no longer be effective!
This schedule was originally planned to provide a very strong telemetry signal for schools to use during daylight hours and for amateur operation at night (and also at weekends and over holidays)
We have already experienced a short period of full sunlight but this time it looks like the spacecraft will be in this situation for more than eight months until sometime in April next year
In addition to the additional thermal effect that will occur during this period, we also expect that the spin rate will increase The reason for this effect is not yet fully understood but may be related to the amount of current flowing from the solar panels to the spacecraft bus being sufficient to cause a torque effect with the earth's magnetic field
We have therefore decided to have AO73/FUNcube-1 initially operate for alternate periods of one week in either safe or educational modes This should enable us to evaluate whether the currents do affect the spin rate Safe mode provides low power telemetry and education mode the usual high power telemetry It will also enable an analysis to see whether the satellite becomes hotter or cooler in each mode
This will be a new experience for the spacecraft so the capture of the largest possible amount of telemetry remains an important tool for the team to have We are very grateful to everyone who continues to upload the telemetry they have received to the Data Warehouse It is invaluable
In addition to AO73/FUNcube-1, the FUNcube-2 transponder on UKube-1 remains operational and EO88/Nayif-1 continues to operate autonomously with the transponder on when in eclipse and high- power telemetry in sunlight
LAST MINUTE UPDATE: AO73 is now in safe mode (low power beacon only, no transponder) We have set this mode as the satellite is about to enter a period of continuous sunlight (for about 9 months) There is more information at https://funcube org uk/news/
The plan is to change to education mode (high power beacon) next Friday

Interns Create Visualization of NASA Space-Ground Communications
For the first time ever, people worldwide can get an inside look into what it takes to enable communications for nearly 40 NASA missions, thanks to a small team of college students
NASA's Near Earth Network (NEN) leverages more than 15 antennas across the globe to provide a downlink for critical space and Earth science data collected by the agency's satellites A new web-based app called NEN Now shows, in real time, simulations of the complicated maneuvers these antennas undergo to link with passing satellites, following them from horizon to horizon as the data streams to the ground
"NEN Now opens a window to the public, sharing live updates about which of NASA's spacecraft are communicating with the Near Earth Network," said Barbara Adde, director of policy and strategic communications for the Space Communications and Navigation (SCaN) program office at NASA Headquarters
"Curious about what NASA is studying? You can click on a link and find out what research that spacecraft is collecting data for and sending down to Earth right at that moment "
Not only will NEN Now help the public understand space-to-ground communications systems, but the tool will help technical and project managers monitor the status of the network in detail, providing information such as the actual position of the antennas' dishes
At SCaN's request, Goddard modeled NEN Now after a similar app, called DSN Now, built by NASA's Jet Propulsion Laboratory in Pasadena, California, for the Deep Space Network (DSN) The DSN provides communications services for missions in deep space and is managed by JPL
Ryan Turner, a ground system manager, had an idea to efficiently and effectively develop the NEN app at Goddard by leveraging the skills of college students and utilizing experienced engineers to provide guidance
"We started with three interns, who worked with the public engagement team, NEN engineers and the GMSEC to lay out a prototype," Turner said
GMSEC is the Goddard Mission Services Evolution Center, which creates data system solutions across multiple projects and disciplines "It gave everyone a sense of what would be possible if we created an operational version of the system "
Naje Fields was one of the first interns on the project in summer 2015 "Our biggest challenge for the prototype phase was to figure out how to get the data from the real-time status server at [NASA's Wallops Flight Facility in Virginia] to Goddard and into our app," she said She and her partners, Kierra Harrison and Wallace Phillips, used a number of networking and security techniques to make it happen
The prototype might have been ambitious for three college interns to complete over the course of 10 weeks, but it was very well- received, allowing Turner to establish a year-round program and to take on more interns in the following summers
Those groups have worked on multiple projects, including adding commercial ground stations to NEN Now, implementing a NEN Now mobile app, designing the Space Network (SN) Now for Goddard's other communications network, and developing a 3D interface for NEN Now
Both NEN Now and DSN Now have been incorporated into a larger app called SCaN Now An additional application for SCaN's third network, the Space Network, is also being created by this intern team, rounding out the real-time status display capability for all three of SCaN's communications networks NEN Now is now available to the public at:
