VHF+ Station Prep for Winter Field Day 2020

We’ve busy preparing for Winter Field Day 2020. We’re planning to expand our station coverage to include more bands above 6m.

We are planning on adding the 1.25m, 33cm, and 23cm bands to our Winter Field Day 2020 setup. Jamey, AC1DC and I put together a new mast to support Yagis for these new bands a few weeks back.

Rovers for New Bands

Jon, AC1EV and Jerry, K1OKD have been working on a Rover set up so that folks can make contacts on these new bands and help out all of the Winter Field Day stations in our area.

VHF+ Station Testing for Winter Field Day 2020

VHF Station #1 Test

The first station that we put together (VHF #1) is based upon an Elecraft KX3/PX3 combination. We added an outboard 100W HF amplifier and two Tranverters to the radio to cover 160m-10m, 1.25m, and 33cm. We plan to use this station for VHF+ contacts during the daytime and for HF operations at night. All of our Winter Field Day Stations will have computers for logging and digital modes and they will all support Phone, CW, and Digital modes. Also, we will be using networked N1MM+ for logging at Winter Field Day.

VHF Station #2 Test

The second station we put together (VHF #2) uses an Icom IC-9100 Transceiver and will cover the HF bands, 6m, 2m, 70cm, and 23cm. It will have a computer-controlled satellite setup that uses a Mac Laptop for tracking as well as a windows computer for logging, digital modes, and CW. The IC-9100 has 100w out on the HF Bands, 6m, and 2m as well as 70w output on the 70cm band – plenty of power for Winter Field Day. The 23cm side of the IC-9100 does 10w out so we’ve added a 100w amplifier for this band. The combination of the amp and the high-gain 23cm antenna that we are using will make our Effective Radiated Power (ERP) on 23cm in excess of 2,000w.

Thanks to some great work by Jon, Jerry, Jamey, and Anita our two most complex stations are ready to go. We will be testing our 3 remaining HF station including one which supports 160m in the near future.

We hope that you’ll join us for some operating fun at Winter Field Day! You can sign-up for operating, roving, and/or station set up at Winter Field Day 2020 here.

EME Station 2.0 Part 5 – Control Cables and Rotator Controller

Snow is coming to New England this weekend so we wanted to get the control cables run to our new EME Tower before the ground is covered with snow. The project involved installing a Utility Enclosure…

We made some more progress on our 2m EME Station Project this past weekend. We began by installing a Utility Controller on our new EME Tower. With this done, we next ran three control cables through the conduits between our shack and the Tower. The control cables connect to our Azimuth Rotator, Elevation Rotator, and a planned MAP65 Switching and Preamp System.

With the cables run, we connected our Azimuth Rotator to a Green Heron Az/El Rotator Controller in our shack. This enabled us to get our Azimuth Rotator configured and tested.

You can read more about this part of our EME Station Project via the link above.

The next step in our EME Station Project will be to assemble the antennas that we have on order from M2 Antennas Systems and install them along with an H-Frame and related gear on our new Tower. We are hoping that the winter weather will allow us to get this done before spring.

Winter Field Day VHF+ Preparations

We are continuing to make progress on our preparation for VHF+ Operations at Winter Field Day (WFD) 2020. We had a lot of fun on the VHF+ bands at WFD 2019 and we are planning to add some more bands for our operation this year.

New Winter Field Day VHF+ Mast

Jamey, AC1DC an I put together a new mast and antennas for the VHF+ bands this weekend. Our new mast comes from Max-Gain Systems. It is a little over 30 ft high and is guyed at 2 levels. We can rotate the mast at the base using the arm-strong method. We’ll be feeding the mast with LMR-600 coax.

Our VHF+ mast holds yagi antennas for the 23cm, 33cm, and 1.25m bands.

Jerry, K1OKD and I assembled a new 220 MHz Yagi for this setup last weekend. We are using rear-mounted yagis on our mast to simplify mounting and feedline connections and to keep the overall weight on the mast at a reasonable level.

With 50 – 100w in, these antennas will produce 450 – 2500 watts of effective radiated power.

Transverters and Transceivers

The Transverters for our VHF+ station have also arrived from Q5 Signal. The unit shown above is for the 33cm (902 MHz) band.

Transverters upconvert transmitted and downconvert received signals from one frequency band to another (ex. from the 33cm band to the 28 Mhz or the 10m Band). They also typically include a power amplifier stage that generates 25w – 50w of output power on the target band.

Our station will use transverters along with an Elecraft KX3 Transceiver to put us on three VHF+ bands as well as to add an additional 100W HF Transceiver to our WFD Setup. We will also have an Icom IC-9100 Transceiver to cover the HF, 6m, 2m, 70cm, and 23cm bands.

The Winter Field Day Team is planning some station testing sessions in the near future to get all of our HF and VHF+ rigs ready. All Nashua Area Radio Society Members are invited to join us for these sessions to learn more about the equipment that we use at Field Day. We’ll post information in our Field Day Forum and on our Calendar as these sessions are scheduled.

You can read more about our plans for Winter Field Day 2020 in Jerry’s article here on our Blog.

See you at Winter Field Day!
