An 80m Broadband Matching System

We installed a 75m loop for SSB operation on our tower when we built it. The loop is full size and is diamond shaped so that our lower SteppIR DB36 yagi can rotate inside of it. The loop is fed at the bottom corner about 20 ft up from the ground. It works great for … 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

A Portable Satellite Station Part 2 – 2.0 Station Goals and Antenna System

We came upon the M2 Antenna Systems booth while walking around the exhibit halls at Dayton last year. M2 had one of their LEO Pack satellite antenna systems on display there. This got us thinking about building a new, more capable version of our portable satellite station. The LEO Pack is a relatively lightweight circularly … Continue reading

Fall Antenna Projects – A New Low-Band Receive Antenna System

Anita and I like to take advantage of the mild fall weather to do antenna projects at our QTH. We have completed two such projects this fall – the installation of a Two-Element Phased Receive System and a rebuild of the control cable interconnect system at the base of our tower. Our first project was the … Continue reading

A Portable Satellite Station Part 4 – 2.0 Station First Contacts!

With our new 2.0 Satellite station built, tested, and packed; we were ready to try it in a portable environment. Fortunately, the Nashua Area Radio Club had a Technician License class coming up and we thought that the new station test would be a great way for our students to learn about Amateur Radio Satellites. Final … 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

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

Station Automation Part 3 – Antenna Cutover And Final Integration

The final article in our microHAM installation series will be about the cut-over, configuration and integration testing of our station. The first step in the process was to bring the second radio in Anita’s (AB1QB) position into the microHAM system. We also added a PR 781 microphone and boom from Heil Sound to her setup … Continue reading

Station Automation Part 2 – Second Operating Position And Antenna Switching

We have continued our work on automating our station’s operation with using microHAM equipment. I have integrated the second operating position into our station into the system via the installation of a second microHAM MK2R+ SO2R interface and two more Station Master Deluxe (SMD) antenna controllers. This position has a Yaesu FTdx5000 Transceiver and an Icom IC-7600 … Continue reading
