Today is Giving Tuesday

Giving Tuesday is live and today is that Tuesday.  Right now if 5 people give a recurring donation of $5 a month the club gets an extra $200.  Or if we happen to hit 50 donors of $10 we can get an additional bonus $200.  If you were looking for a way to continue to support amateur radio at CWRU please donate.

We are in the process of replacing our towers which is a $100,000 project that we were lucky enough to get a grant to cover a large portion of, but the antennas will need up keep and maintenance.  Donations will help the club continue to be an on air presence as well as a resource for students, faculty, and the general CWRU community.

They’re playing our song! (WWV/H Scientific Modulation)

Tune in to WWV at 8 minutes past the hour or WWVH at 48 minutes past the hour to hear the first test signals from the WWV Scientific Modulation Working Group, announced by yours truly. More information here: www.hamsci.org/wwv

If you aren’t near your HF radio, you can tune in via SDR at rx.linkfanel.net, or call in to the VoIP time service for either station Hawaii. To hear these broadcasts, dial (303) 499-7111 for WWV (Colorado), and (808) 335-4363 for WWVH (Hawaii).

Slight update, due to a phone hardware complication at WWV their phone number is not currently playing the science test signals. This situation may change moving forward. Due to the custom nature of the stations apparently simple problems don’t always have straight forward solutions. You can still call in to Colorado if you want to check that time is progressing linearly, but you won’t get to hear scheduled tones, chirps, and noise bursts on your phone. If unscheduled tones, chirps, and noise bursts are present on your phone please contact your service provider. If you want to hear science from WWV on 8 minutes past the hour you’ll need to do it over the air using receiver belonging to you or someone else.

W8EDU Enters the Fall Semester

After a nice, refreshing summer break, the Case Amateur Radio Club has started preparations to get back on the air. Our Faculty Advisor, David Kazdan, has sent out the initial call for new officers to the freshman circles, with the assistance of our current sophomore and junior student members. One of these new members which has been eager for the club to resume regular operating hours is international student Andrej Antunovikj from North Macedonia, home call sign Z35TUN. He has prior experience working in his local ham radio club back home, so he is a welcome addition to our club!

We eagerly await what experiences this new semester will bring us. Some initial plans are weather satellite reception, increased presence in HF contests, and teaching new members about the ARRL radiogram system (and as a result, traffic nets.) Do join us to find out what we have in store!

Boats on the Air (BOTA)

We activated Lake Erie for BOTA tonight! Details here: https://www.boatsontheair.com/ovation-on-lake-erie-jul-3-aug-1-2021/

ARRL Frequency Measuring Test (April 2021)

The Case Amateur Radio Club W8EDU participated in the Frequency measuring test this past week, scoring with less than 2 Hz error on all frequencies. Our best score was on 7 MHz, where the club scored an error of just 10 millihertz, or a little over 1 part per billion!

Operating the station were Frankie Bonte KE8HPA, Adam Goodman KJ7RPK, Sergei Prokvolit KE8QFY, and Skylar Danhoff KD9JPX.

We also had several current and former club members participate, including David Kazdan AD8Y, Jim Galm W8WTS, and John Gibbons N8OBJ. We especially congratulate John, who scored in the infamous green box for less than 1Hz error on all frequencies!

We hope to see everyone at the next Frequency Measuring Test!
