Our Portable Satellite Station antenna system uses a pair of Advanced Receiver Research Remote preamplifiers at the antennas to boost weak signals. These preamps have RF sensing and switching to protect…
PTT Router Front Panel
Our Portable Satellite Station 3.0 is coming together and has been tested thanks to help from several NARS members. Part of the project is to improve the sequencing system which manages antenna mounted preamplifiers. These improvements involved the design and construction of a simple Push To Talk (PTT) router. The article above explains the design, construction, and integration of this PTT Routing devices. It was a great homebrew addition to our Portable Satellite Station setup.
The video above is a capture of the school’s contact. It was very easy to receive the ISS downlink on our portable backup ground station. I heard the downlink a few seconds before the ISS came up on the horizon and the audio was solid for the duration of the contact. We can only hear the astronaut’s side of the contact as we cannot receive the school’s uplink from Raleigh, NC. The ISS pass began here in New Hampshire part way through the school’s session so we did not hear the first few questions.
Update on Portable ISS/Sat Station 3.0
Portable ISS/Sat Station 3.0 Antenna System
Work on our upgraded primary Portable 3.0 Station which includes a larger antenna system using switchable circular polarity is progressing well. The portable tower, upgraded rotator system, and the new, larger 2m and 70cm circularly polarized antennas are complete. We are just waiting for a few additional components to arrive here and the upgraded portable ground station should be ready for its first test at our Technician License Class later this month.
More on Today’s ISS Crew Contact
You can see a live stream of the ISS Contact from the school above. There is a great deal of planning which goes into an ISS Crew Contact such as this. We are working closely with Hudson Memorial School on their project and their school is also beginning a High-Altitude Balloon Project with us in a few weeks.
The ISS Crew Contact today was exciting to listen too and we are looking forward to being able to share this experience with Hudson Memorial School in the near future.

AMSAT’s next Fox-1 satellite, Fox-1D, is scheduled for launch on January 12, 2018 at 03:58 UTC (Thursday, January 11th at 10:58 PM EST) from Satish Dhawan Space Centre in Sriharikota, India. Fox-1D will launch as part of the PSLV-C40 mission on board a Polar Satellite Launch Vehicle with Cartosat-2F, an imaging satellite for the Indian government, and 29 other payloads.
In addition to the Fox-1 U/v FM transponder, Fox-1D contains a number of exciting experiments, including a camera built by students at Virginia Tech, the University of Iowa’s HERCI (High Energy Radiation CubeSat Instrument), and AMSAT’s L-Band Downshifter which will give amateur radio operators an opportunity to experiment with a different uplink band. Stay tuned for more information about the launch and early operations of the satellite.
