New EME antenna installation: Raise High the 2-Meter Beam, Engineer!


John Gibbons, N8OBJ is the Club Technical Advisor (and the full-time director of Sears Lab, the electrical engineering department’s undergraduate laboratory, providing an EE walk-in clinic and surface-mount compounding pharmacy well used by W8EDU members).  He built the new 2-meter beam from the parts purchased after the old beam’s destruction last summer.  He has made a project the past few weeks of removing the alt-az rotor for cleaning and recalibration, and installing rotor, antenna, feedline harness, and feedline before fall term.

The antenna was installed in 2012 for earth-moon-earth communication and was used successfully for that in 2016.  Electrical and mechanical engineering senior projects have included transmit and receive amplifiers and moon-tracking software.  It’s a nice antenna:

We note that Cleveland has a magnetic variance of 8 degrees west; we will verify azimuth calibration against Polaris next clear night Cleveland might grant us.

Not a bad thing to be half a bubble off plumb about.  Thanks for your efforts, John, and we all look forward to using the antenna.

W8EDU mourns the passing of Professor Bill Schultz AC8CO. A graduate of CIT in 1964 (BSEE) and 1967 (MSEE), and of CWRU in 1979 (Ph.D), Bill was a registered Professional Engineer, a Senior Member of IEEE, a professor at CWRU, and an active member of W8EDU for many years. He will be dearly missed.

Funeral plans: Saturday 3:00 PM Pioneer Memorial Presbyterian Church, Solon Road, Solon. Visitation is 1:00-3:00.

4th of July Visit to MIT

I was graciously invited to visit the MIT Radio Society on the Fourth of July.  I am working in Boston this summer and they have an excellent view of the city’s fireworks as well as the height to see fireworks from neighbors in all directions.  We were in and around the W1XM shack.  W1XM is located on the roof of MIT’s Green Building.  Located on the same roof is the building’s radome.  The MIT Radio Society is working on re-purposing the dish (and dome) for radio astronomy purposes.  I was able to go inside while some of the work was being done.  MIT Radio Society President Daniel KC1EPN and another member were working on identifying the internal electrical connections (and their sometimes unrelated interconnections).

We at W8EDU are starting to plan for the 2024 eclipse.  The path of the 2024 eclipse puts Cleveland nearly centered in the path of totality.  As such we are in the beginning stages of planing what we want to be observing from totality.  We went to the HamSci Conference 2018 where there were multiple presentations on interesting on ionospheric anomalies/disturbances that happened during the 2017 eclipse.  The entire scientific community was able to make some new discoveries and confirm some long held but unable to be tested theories with that eclipse.  The new information opens the door to new and interesting questions that we want to be a part of researching when the 2024 eclipse passes over us.  As part of this we are in the preliminary phases of discussion with MIT’s Haystack Observatory.  From what I saw of the radar dish operations at W1XM I’m hopeful that we can include them in our plans.  We know that our plans for the 2024 eclipse will likely involve multiple departments (Astronomy, as well as EECS, maybe Physics, Statistics, EEPS, and others), but we are also hoping to involve other schools and universities in our plans.  We also hopefully can provide data to other institutions from our location in totality to further their research.  MIT Haystack is one of the groups we hope work with and to provide data to.  I am hopeful that we can get the MIT Radio Society involved in our future plans especially ones that are involving MIT’s Haystack Observatory.
