160m Portable Antenna System for Field Day

The Nashua Area Radio Society tries to do something new each time we engage in an Emcom or other major operation. We decided to try Winter Field Day for the first time this year and we made one of our new elements a capable portable station for 160m. It’s almost impossible to field an effective 160m … Continue reading

Satellite Station 4.0 Part 2 – Antennas

Our current Satellite 3.0 Antennas have worked well in their portable configuration. We’ve had them to License Classes, Field Day, Ham Fests, and ultimately to Hudson Memorial School for the ISS Crew Contact there. As you can see from the photo above, the weight of the antennas causes the Fiberglass Cross Boom that we are … Continue reading

Satellite Station 4.0 Part 3 – Antenna Integration and Testing

Sometimes we learn from problems and mistakes. We all go through this from time to time. It is part of the learning aspect of Amateur Radio. My most recent experience came while integrating our new tower-based satellite antenna system. After the antennas were up, initial testing revealed the following problems: A position sensing problem in our … Continue reading

A 40m High Performance Antenna for Field Day

The Nashua Area Radio Society has been using a 3-element wire beam antenna for Field Day for the last several years. The antenna uses three guyed 50 ft. fiberglass masts from Max-Gain Systems. The antenna uses three inverted-V style elements separated by a little over 50 ft. Since we are in the northeastern United States, we … Continue reading

New 70cm Yagi

We decided to replace our current 70cm yagi with a newer, higher performance one from M2 Antenna Systems. We choose the M2 432-9WLA. The new antenna has higher gain and a cleaner pattern than our current 70cm yagi. It also has a longer boom. The first step in the project was to assemble the antenna … Continue reading

EME Station 2.0 Part 3 – Phase Tuned Receive Coax Cables

Our new 2M EME station will have Adaptive Polarity capability via MAP65. MAP65 requires that received signals from the Horizontal and Vertical planes of our antennas arrive at the receivers in our shack precisely in phase with each other. We decided to use a pair of LMR-600 coax cables for the receive side of our … Continue reading

EME Station 2.0 Part 4 – New EME Tower Is Up!

Our goal for this phase of our EME Station Project is to get our new tower up, install the Azimuth Rotator and Mast, and run the hardline and coax cables for our antennas from the shack to our new tower. Our EME tower is constructed using Rohn 55G tower sections. It will be 26 ft tall … Continue reading

Satellite Station 4.0 Part 4 – Tower Camera and J Mode Desensitization Filter

It is winter here in New England and it is not the best time of year to work outdoors. I have been able to complete a few finishing touches on our new Satellite and 6m Tower. The first enhancement is the addition of an SV3C IP Camera. The camera allows us to see what is going … Continue reading

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 1 – New Tower

Our plans for Satellite Station 4.0 are based, in part, on the idea that we can extend our current remote operating environment to include Satellite Operations. Now that our ISS Crew Contact is complete, the antennas from the current Satellite Station 3.0 can be permanently installed at our QTH. The first step in the project … Continue reading
