Upgrading our 2.0 Satellite Station for ARISS Contacts

We have been working with Hudson Memorial School near Nashua, NH to prepare for a possible ISS crew contact. The ARISS folks work with schools and their Ham Radio helpers to prepare for these contacts. ARISS provides recommendations for ground station equipment to help ensure a good experience for the students. The ground station recommendations provide a solid set of specifications to support communications with the ISS on the 2m band. The recommendations include things such as:

  • A requirement to build both a primary and a backup ground station
  • Radio and power specifications (a 200W amp is recommended)
  • Antenna specifications including recommendations to provide for switchable LHCP and RHCP
  • Computer controlled azimuth/elevation positioning of antennas to track the ISS
  • Use of a receive preamplifier at the antenna
Portable Satellite Station 3.0 Antenna System

Portable Satellite Station 3.0 Antenna System

We have recently completed construction and testing of our Portable Satellite Station 3.0 which was built specifically to meet the primary station requirements for our ISS contact.

Our plan is to add some upgrades to our Portable Satellite Station 2.0 to create a Portable 2.1 Station which meets the backup station requirements. These upgrades will include:

All of the equipment needed to upgrade our 2.0 Portable Station to 2.1 is either here or will arrive shortly. Here’s some more information on the planned equipment.

Icom IC-910H Transceiver

Icom IC-910H Transceiver

The Icom IC-910H was Icom’s flagship Transceiver for Satellite work before the IC-9100 was released. It’s a very nice satellite radio! Dave, K1DLM graciously lent us his IC-910H for use in our backup station.

Green Heron RT-21 AZ/EL Rotator Controller

We are also planning to build a second Raspberry Pi Rotator Interface for it.

M2 Antenna Systems PS2MCP8A Polarity Switch

M2 Antenna Systems PS-2MCP8A Polarity Switch

M2 Antenna Systems recently added a new 2M polarity switch, the PS-2MCP8A, designed for use with the 2M antenna in their LEO Pack which we are using in our 2.0 Antenna System. We will be installing this relay as well as a PS-70CM polarity switch relay for the LEO pack’s 70cm antenna as part of the 2.1 Antena System upgrade.

DXEngineering EC-4 Control Box

We will add another DXEngineering EC-4 BCD Control Console to control the polarity switching relays on the upgraded antennas.

m RM ITALY LA-250V Amplifier

RM ITALY LA-250V Amplifier

The final new component in our 2.0 to 2.1 upgrade is the addition of a 200W RM ITALY LA 250 power amplifier. We have opted for the version of this amplifier with the cooling fans. The unit is very well made and we are anxious to see how it performs on the air.

Some of our readers might be wondering what we are planning to do with all of Portable Satellite Ground Station equipment in the long run? We plan on keeping the 1.0 Portable Station for grid square activations and demonstrations. Its simple, battery-powered approach and small antenna make it ideal for this sort of work.

The upgraded 2.0 Portable Station with its enhanced polarity switching will become our transportable station for License Class and Field Day use. It will be converted at the end of 2018 to use our Icom IC-9100 Transceiver that is currently part of the 3.0 station.

We plan to use the Portable 3.0 Station through the year (2018) to support the planned ARISS contact, Field Day, and some demonstrations at local Ham Fests and schools. Once these are complete, we plan to permanently install it here at our QTH and it will become our main satellite ground station at our home QTH.

You can view all of the articles about our Portable Satellite Stations via the links below.

We will begin construction of the 2.1 upgraded station once a few remaining components arrive here. We plan to share some more about the construction and initial testing of our 2.1 Portable Station here.

ISS Crew Contact

We have been working with Hudson Memorial School to help them secure and prepare for an ISS Crew Contact. We are hoping to support their ISS Crew Contact using an upgraded version of our Portable Satellite Ground Station. A school in Raleigh, North Carolina had their ISS Crew Contact today and I decided to record the downlink from the ISS to test our backup Portable 2.0 ISS/Satellite Ground Station.

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.

HAB-2 Sets Altitude Record! – Nashua Area Radio Society

We flew our High-Altitude Balloon for the second time this past weekend. Our second High-Altitude Balloon Flight (HAB-2) was part of a STEM learning project that we did with STEM club students at Bishop-Guertin High School in Nashua, NH. The students did all of the flight prep and launched HAB-2 at approximately 11 am ET from a school in Winchester, NH. Parents, teachers and local students joined us for the launch as did several members of our HAB team.
