Satellite Station 4.0 Part 6 – Tower Finishing Touches

We recently completed the finishing touches on our new VHF/Satellite Tower. The first step was to install a second set of entry conduits into our shack and a new ground block for our satellite antennas. This involved installing 4″ PVC conduits into our shack. The new entries are very close to the base of our … Continue reading

Satellite Station 4.0 Part 10 – Adding 23 cm To Our Satellite SDR

We’ve recently received our L24TX Transmit Converter from Down East Microwave. The unit is compact, simple, and produces up to 25W output in the satellite section of the 23 cm band (1260 MHz – 1270 MHz, actually 24 cm). The L24TX is a transmit-only device that is intended to enable L-band uplinks for Satellite use. … Continue reading

Satellite Station 4.0 Part 7 – Flex SDR Satellite Transceiver

A major part of our plans for Satellite Station 4.0 includes the ability to operate our home satellite station remotely over the Internet. We’ve been using our Flex-6700 Software Defined Radio (SDR) as a Remote Operating Gateway (GW) on the HF Bands and 6m for some time now. Our latest project is to upgrade our … Continue reading

Satellite Station 4.0 Part 8 – GPSDO Frequency Locking

Frequency accuracy and stability become more challenging for transceivers that operate at 400 Mhz and above. Our 4.0 Satellite Stations operate at frequencies approaching 1.3 GHz and we want to be sure that their operating frequencies are accurate and stable. Our Flex-6700 SDR includes a GPS Disciplined Oscillator (GPSDO) so the radio and all of … Continue reading

A Portable Satellite Station Part 7 – Plans for a 4.0 Station

We have begun looking ahead to Satellite Station 4.0 and where we want to go next after our ARISS crew contact is complete. Our goals for the Satellite Station 4.0 include: A permanently installed version of our 3.1 Station which can be operated remotely over the Internet Upgraded Transceivers which add Pan Adapter/Waterfall display capabilities Enhancements … Continue reading

Software Defined Radio/Remote Operating Gateway Part 2 – Client/Server Setup And Software

The next step in our Software Defined Radio/Remote Operating Project was to build a Remote Operating Gateway System in our shack and setup Client PCs to operate our station remotely. In a previous article, we explained how we integrated a FlexRadio 6700 Software Defined Radio (SDR) into our station to create a platform to build our remote operating project around. … Continue reading

Software Defined Radio/Remote Operating Gateway Part 3 – On The Air Remote!

In the previous articles in this series, we explained how we integrated a FlexRadio-6700 Software Defined Radio (SDR) into our station and how we used it as a platform to build the Remote Operating Gateway for our station. The project has turned out to be somewhat involved so we will be providing a series of articles to explain what we did: Part … Continue reading

Software Defined Radio/Remote Operating Gateway Part 1 – System Design And Hardware Installation

We’ve been planning to add a remote operating capability to our station for some time now. We also did some previous work with a FlexRadio Software Defined Radio (SDR) in our station and we felt that an SDR would be a good platform to build a remote operating project around. We decided to combine our remote operating … Continue reading

Sights from the New England Tech Trek (NETT) at NEAR-Fest

We have been working on project to scale our open house activities to provide an opportunity to learn about Amatuer Radio and to showcase some of the modern, “hi-tech” aspects of the Amatuer Radio Service. This project was debuted at the NETT event at NEAR-Fest. We used our Portable Satellite Station, Remote Operating Gateway, and … Continue reading

Plans for 2017 Station Upgrades – Radio, Shared Amplifier, and Remote Op Enhancements

We have a number of station upgrades planned for this fall. Our planned upgrades include: Enhancing our FlexRadio 6700 based Remote Operating Setup to include additional remote control client options, better networking via the Internet, and better integration with our microHAM system – you can read about this completed project here. Upgrading the second radio in … Continue reading
