Listen In On The Council Rock ARISS Contact on Thursday!

Students at Council Rock High School South in Southampton, PA will be talking with Astronaut Drew Morgan, KI5AAA aboard the ISS on Thursday. The ISS will be over our area here in the Northeastern Unit States beginning at about 12:55 pm eastern time on Thursday, December 5th. Council Rock’s ARISS Contact is made possible by the ARISS Program.

You should be able to hear Drew on the ISS voice downlink at 145.800 MHz FM. The ISS pass will be a high one over our area. As a result, we should be able to hear the downlink using a good vertical antenna and perhaps even using an HT.

Students, Teachers, and their Warminster ARC partners have assembled and tested their ISS Ground Station in preparation for their contact. Several of the students used their station to make their very first Amateur Radio Contacts.

Plans for Contact Day

Here’s some more information about the plans for the contact from Andy Vavra – KD3RF, a Warminster ARC member, who has been working with the Students and Faculty at Council Rock H.S. South to prepare for their contact:

I’m Andy Vavra – KD3RF, and one of several mentors from the Warminster Amateur Radio Club (WARC) who are helping students from Council Rock High School South in Southampton, PA make contact with the International Space Station on Thursday, December 5th as part of NASA and AMSAT’s ARISS program…

Several Warminster Amateur Radio Club members including Michael Shanblatt (W3MAS,) Irwin Darack (KD3TB,) Joe Horanzy (AA3JH,) as well as myself (KD3RF) and ARISS advisor Fred Kemmerer (AB1OC) have been mentoring the teachers and students to help them set-up and operate a permanent satellite station at the school which they will use to engage in a conversation with the astronauts on the International Space Station (ISS) this coming Thursday, December 5th at 17:56 UTC (12:56 pm Eastern Time.)…

Council Rock South has an active Ham Radio club (KC3NNG) with more than 30 student members in grades 9 – 12 who are getting started on their Ham Radio journeys. The club is under the sponsorship and guidance of four teacher/advisors from the school’s STEM program; Gerald Fetter (K3OHI,) Joe Warwick (KB3ZED,) and Jeff Warmkassel and Fred Bauer who are working on getting licensed.

The student members represent all segments of Council Rock’s diverse community and are interested in continuing their education in fields such as engineering, science, technology, marketing and business.

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.

EME Station 2.0 Part 1 – Goals and Station Design

EME or Earth-Moon-Earth contacts involve bouncing signals off the moon to make contacts. An EME station provides a means to make DX contacts using the VHF and higher bands. There are also some EME Contests in…

We made some 2m EME contacts a while ago using the 2m antenna on our tower at about 112′. This experience created interest on my part in building a more capable EME station at some point in time. Well, the time has finally arrived.

The article above explains our goals, plans, and design of a new 2m EME station at our QTH. The article covers plans for a new tower, antennas, and an SDR-based receive system.

Our plans are to build an 80th percentile station that utilizes four large, dual-polarity antennas in an array. The station will use the JT65 digital protocol and will support adaptive polarity via MAP65. The new setup will utilize WSJT and MAP65 software created for EME use by Joe Taylor.

Our plans are to begin construction of our new EME Station later this week with a new 26′ Rohn 55G tower going in first. You can read all about our plans via the link above.
