Slightly random… I have a Cisco SPA504G VoIP phone which I acquired ages ago and connected to Hamshack Hotline back when the UK still got 5 digit numbers.
The phone isn a 4-line one and subsequently I got a Hams over IP number for line 2, then an extended freedom network number on line 3. After that the phone sat for ages with only the three lines in green, waiting for a fourth.
I did consider buying a VoIP service to transfer our POTS number to once we upgraded to FTTP and lost the copper line. But then, all we used the landline phone for was ignoring junk calls, only ever making calls using my mobile phone which has free minutes and SMS, or using WhatsApp. So the landline went.
And still that fourth line was dark, just sitting there.
Along came CNet. I have had an interest in all things telephony and telegraphy from an early age. I always wanted a small mechanical PABX – I still don’t have one but I do have an eye out for a couple of old dial phones from my childhood. And that’s where the interest in CNet came from. Having investigated further I realised I could use that fourth line for access, and so it happened.
For last year’s Field Day, I took a stab at networking a couple of computers together with an ethernet cable so that our N1MM+ logging software could be synced up. It was both surprisingly easy to do, but equally daunting due to the curious lack of reasonably digestible tutorials tackling the topic on the interwebs. So now that Field Day is again upon us, I felt that same sort of dread that comes from staring up at a steep learning curve. Because quite frankly, I could not remember at all how to create a N1MM+ computer network. I checked back at my blog page on the topic, and was dismayed at how little of the process I documented. So, I am here to rectify that.
Here is my use case. I want to have three computers with Windows 10 operating systems host logging software (N1MM Logger Plus) for a multiple station ARRL Field Day event. All of the computers need to be synchronized with each other in order to avoid such dreaded contesting faux pas as “dupes”, i.e., getting the same person twice. I also do not want to have to rely on an internet in order to maintain communication between these computers.
As far as hardware goes, I already was in possession of three (quite aged) computers. I splurged on three new 25′ ethernet (CAT 6) cables (one for each computer), and a Linksys 8-Port Gigabit Ethernet Switch. I set up the computers simply by plugging one end of an ethernet cable into its ethernet port, and the other end of the cable into the switch. Remember the gigabit switch does need power to operate!
Before I began networking the computers, I had updated all of the necessary software, including Windows and N1MM+. All of the computers need to have the exact same version of N1MM+, as well as exactly the same inputted contest information, before N1MM+ is able to synchronize between multiple stations.
Once the hardware was gathered and the software was up-to-date, I followed the step-by-step procedure documented below.
Step 1: Go to internet icon, click, and “Open Network & Internet Settings”.
Step 2: Select “Ethernet” on left, and then “Network and Sharing Center” on right.
Step 3: The “Unidentified Network” is set to “private” which is what I want it to be. For contrast, my wifi network is set to “Public” (see arrow on the left). Click on the “Ethernet” hyperlink.
Step 4: Click on “Properties” of the first box that pops up. Then click on “Internet Protocol Version 4 (TCP/IPv4)”.
Step 5: Click “Use the following IP address” and add in “192.168.1.200” for “IP address”. The “Subnet mask” should just show up as 255.255.255.0. While I am no expert by any means in networking computers, I do think you can choose the last three digits of your IP address from 1 to 255 254 [Correction sent to me by my favorite critic, AC1JR!] I picked “200” rather arbitrarily. Once you are done, click “ok”, “ok”, and “close” on the multiple windows.
Step 6: If you need to make your network private because it is showing as public (see Step 3 above), you need type “secpol.msc” into the search bar and press enter.
Step 7: In the pop-up window, click on the “Network List Manager Policies” under the “Security Settings” tab. Then click “Unidentified Networks”. In the next pop-up, choose “Private”. Hit “Apply” and then “Ok”. Your “Unidentified Network” settings should now say “Private”.
Step 8: Open the file manager and click on “Network”. Your computer’s name should be listed there. My computer is named “PC-1”.
Step 9: Now it is time to network your second computer. Go back through Steps 1-8, but this time on the new computer. Below shows all of the steps ordered numerically. Don’t forget to change the ethernet connection to “Private” as shown above. The only difference is that you want to assign this computer a different IP address than the first one. I chose 192.168.1.201.
Step 10: Check the “Network” tab in the file manager to make sure the second computer (in my case, “PC-2”) shows up.
Step 11: Repeat these steps as many times as you need to in order to connect all of your computers to the network. Just change the last digits of the newly assigned static IP address, as they all have to be something different. I have three computers that are now linked together.
Step 12: Once your computers are all networked, open N1MM. Under the “Window” menu, find and click “Network Status”.
Step 13: Make sure that the most recent version of N1MM is installed or else you will get an error message when attempting to connect to the other networked computers (in red below). You also need to make sure that everything else about N1MM is identical, in particular that the contest information for the log is the same.
Step 14: When all of the computers are identically set-up, with the same software versions and contest information, open up the “Network Status” window. A bubble will show that gives you an option to turn on “Networked Computer Mode”. Click it!
Step 15: If you see all of your computers listed with no red error messages, your networking efforts are a success! Make sure you have designated one of the computers as the “Master” by checking the appropriate box.
There you have it! N1MM Logger Plus synchronized across multiple stations for Field Day! I hope to catch you on the air!
We are excited to announce that we are celebrating yet another significant milestone for the SatNOGS project as the SatNOGS DB stored its 200 millionth data frame!!!
The milestone data frame
The 200 millionth frame was received on the 31st of October. It was a frame of satellite 47438 – UVSQ-SAT that was received by ground station 2760 – M0GKK-BB. And it was observation #8429588 for the SatNOGS Network.
We can only be thrilled with the enormity of this massive number, and we are also very grateful for these contributions. Congratulations to all for reaching such a fantastic milestone!
The SatNOGS DB
The SatNOGS DB is a component of the SatNOGS project, and it is a collaborative effort to create a holistic, unified, global database for all the artificial objects in space. A point of reference for all the satellites and spacecraft. Data frames are sent to the SatNOGS DB from stations belonging to the SatNOGS Network, as well as independent stations and telemetry forwarders. The SatNOGS DB receives frames from more than 1500 stations around the globe. Tracking over 1650 satellites and 3040+ transmitters in 50 different modes and ten bands. All these add up to the amazing 200 Million data frames received. Thus constituting the SatNOGS DB, the biggest, open-source and crowd-sourced database for openly distributed satellite data.

This week, Dave, KZ9V, shares with us how he modified his 40 through 10 meter end fed half wave antenna to work as a ¼ wave radiator on 80 meters using the window screen ground.
The SatNOGS Network has achieved yet another amazing Milestone! It has reached its eight millionth observation, and we are deeply grateful to the entire Community for this achievement!
Eight million Observations
On the 11th of August 2023, observation #8000000 was uploaded on the SatNOGS Network by station 2173 – PE0SAT-21 in the Netherlands. The observation was scheduled by Jan Van Gils (PE0SAT), receiving data from satellite TigriSat. The eight millionth observation is of good quality.
It is an observation coming from an operational satellite that has been making its way through space for almost ten years.
TigriSat
TigriSat is a 3U CubeSat built by Iraqi students in collaboration with the La Sapienza University of Rome. Its mission is to detect dust storms over Iraq. For this, the CubeSat features an RGB camera. It was launched into space by the Dniepr launch vehicle from Orenburg, Russia, on June 19, 2014. TigriSat is considered to be Iraq’s first satellite.
SatNOGS achieved another milestone!
We are thrilled that SatNOGS has achieved another astonishing Milestone. Everything accomplished is thanks to the active and vibrant community. As is the case, every SatNOGS achievement results from the collaborative work and the continuous efforts made by hundreds of ground station owners around the globe. They are the ones who have made this milestone (and everything) possible by scheduling observations, tracking satellites and, in general, dedicating time and effort to the success of the SatNOGS project.
SatNOGS in Numbers
The SatNOGS network counts over 240+ fully operational ground stations and 150+ in testing mode. The observations come from 1545+ satellites and 2890+ transmitters delivering over 192M data frames. As the numbers show, SatNOGS has significantly expanded and has become the biggest, global, open-source network of satellite ground stations.
Outer Space Open For All (The Libre Space Manifesto)
All Libre Space Foundation’s projects are built to enhance scientific research and knowledge about Space and to enable everyone interested in exploring Space for peaceful purposes. These values are also at the core of the Libre Space Manifesto.

We are excited to share with you the news of SatNOGS achieving yet another milestone, as it has reached 7 million observations.
On the 8th of January, observation #7000000 was uploaded on the SatNOGS Network by station 901 – VE2WI – UHF in Quebec, Canada. The observation was scheduled by Laurent Beaudet, the station owner, receiving data from AMSAT-OSCAR 7. Though the seven millionth observation is of a rather poor quality, it is, in fact, coming from a satellite that has been making its way through space for almost 50 years.
Satellite AMSAT-OSCAR 7 was launched on November 15, 1974, and by mid-1981, it had been rendered non-operational due to battery failure. It was almost 20 years later, in 2002, that it was brought back to life when one of the shorted batteries became an open circuit, and the satellite could operate again. This time using solar panels. What this means is that when in eclipse, the satellite cannot supply enough power to the transmitter to modulate the signal. When continuously illuminated, though, the mode will alternate between A and B every 24 hours. AMSAT-OSCAR 7 became SatNOGS‘s 7 millionth observation 20 years after its resurrection and 49 years after its deployment.
SatNOGS has achieved yet another astonishing Milestone, all thanks to its community. This is the result of the collaborative work and the continuous efforts made by hundreds of ground station owners around the globe. They are the ones who have made this milestone possible by scheduling observations, tracking satellites and, in general, dedicating time and effort to the success of the SatNOGS project.
So let us celebrate this Milestone by taking a closer look at some of the highlights of 2022 for SatNOGS and for everything the SatNOGS Community has achieved in the past year.
Making over 1.670.000 observations, an average of 4.5K observations per day.
Scheduling a sizeable number of observations per deployment ….(There was a time in 2022 that we scheduled over 1800 observations for the first 48 hours of a launch…)
On average, receiving the first signals of the satellites within the first few hours of their deployment.
Contributing to missions with more than 11K observations.. the GASPACS mission was one such mission…
Collaborating with International satellite teams from over 15 countries (Brasil, USA, Spain, Italy, France, Luxemburg, Germany, Finland, Turkey, Israel, UAE, India, Nepal, Korea, Taiwan, and Japan) and more than 20 Universities from around the world.
Celebrations and Goodbyes…
In 2022, SatNOGS and its Community celebrated anniversaries together as satellites continued their lonely yet magical journey through space.
and…
And bid goodbye to satellites that travelled in space and re-entered gloriously.
and
But we were not saddened…
As many of the satellites provided us with wonderful images before they disappeared…
RamSat, a CubeSat built by the students of the Robertsville Middle School in Oak Ridge (Oak Ridge Public Schools), Tennessee, USA, with the supervision and mentorship of the Oak Ridge National Lab, provided us with some breathtaking photos…

and enlighted us with their insightful analyses that taught us beautiful things about space and satellites. The RamSat team was kind enough to share with the SatNOGS Community their findings during RamSat’s quest in space. The team shared some detailed analyses and helpful lessons learned. Among these analyses falls their input on the extreme temperatures RamSat experienced in space due to the intense conditions. https://community.libre.space/t/ramsat-mission-progress/8219/52.
Tracking our very own…
Among the year’s highlights was the return to space of the Libre Space Foundation. It was a moment of great excitement for the LSF team to track the QUBIK mission. To hunt the PICOBUS deployer and PocketQubes, QUBIK-3 and QUBIK-4, as they made it to orbit onboard Firefly Aerospace’s Alpha Flight 2.
Art and SatNOGS
A few months before 2022 was gone, Nye Thompson, a visual artist and a member of the SatNOGS Community, began working on an experimental art project using SatNOGS.
The project uses SSTV transmitted via a satellite as a way to generate and distribute new images. It’s also a kind of networked performance with the satellite.
You can find more details about how you can contribute to SatNOGS art in the dedicated thread on the Community Forum.
Wrapping up …
2022 was a great year for SatNOGS as the Network, and the DB continued to grow, and its Community kept expanding. SatNOGS has now proudly reached over 400 ground stations spread in 50 countries across the globe, having tracked 1177 satellites, 2180 transmitters, 165 million data frames and 7 million observations. It thus remains the world’s biggest open-source network of satellite ground stations.
Led by a Community that fosters collaboration, inclusivity and diversity, SatNOGS welcomes everyone who wishes to contribute their time, knowledge and expertise to the project. A project built and developed to enhance scientific research, knowledge about Space and to enable everyone interested, to explore Space for peaceful purposes, as the Libre Space Manifesto states explicitly.
You are welcome to join the project too, and be part of our next Milestone as we work hard to make…..
We are excited to share with you, the new milestone achieved by the SatNOGS network, as it has reached 6.000.000 observations!
On the 27th of May, observation #6000000 was uploaded on the SatNOGS network by station 1936 – VK4JBE-UHF, in Camp Hill, Queensland, Australia . The observation was scheduled by VK4JBE, the station owner, receiving data from AAUSAT-II, a Danish CubeSat of the University of Aalborg. Although the satellite is operational, it seems to be tumbling in space, resulting in generating rather poor observations.
Achieving the astonishing 6 Millionth Observation is a Milestone that SatNOGS has reached thanks to its community. This too is the result of the collaborative work and the continuous efforts made by hundreds of ground station owners around the globe. They are the ones who have made this milestone possible, by scheduling observations, tracking satellites and in general, dedicating time and effort to the success of the SatNOGS project. So let us take a closer look at some of the astonishing statistics of the project.
SatNOGS in Numbers
The SatNOGS network counts over 265+ fully operational ground stations and 145+ in testing mode. The observations come from 810+ satellites and 1500+ transmitters having delivered over 144M data frames. As the numbers show, SatNOGS has expanded greatly and has become the biggest, global, open-source network of satellite ground stations.
Outer Space Open For all
SatNOGS, much like all Libre Space Foundation’s projects, is built to enhance scientific research, and knowledge about Space, and to enable everyone interested, to explore Space for peaceful purposes. These are all, values that are at the core of the Libre Space Manifesto and guide SatNOGS too.
Thus, the project itself is not only built and developed in a modular, open-source way but the data collected is also distributed openly. The community offers support and guidance in onboarding new members and it even helps satellite teams with their missions. Not only can the community help you communicate with your satellite but they can also guide you throughout the onboarding process. All you need to do is contact the team and provide the necessary details and information about your mission.
