CHOTA 2024 is Announced…

Churches and Chapels on the Air (CHOTA) 2024 will be held on Saturday, 14th September, 2024. John G3XYF, organizer of CHOTA in the UK, has announced the date for this year. For a roster in an Excel spreadsheet of the churches in the UK and US that were registered in 2023, go to this link.

In 2023, I took a leadership role in promoting participation in this low-key event here in the U.S. John G3XYF welcomed this idea. We had about a dozen on this side of the Pond to join in the fun. For 2024, I’ve floated this idea to John for his review and consideration.

What if, at a specified time each hour, every church team QSYed to a specified 20 meter frequency and tried to work each other across the Pond? Of course, propagation and equipment will rule the day. But by incorporating this 10 minute or so period into the framework, it will continue to build a bridge between the two sets of ham operators, no? I’ll post later if this idea has merit with the organizer.

Consider fielding a team at an area church this year! I’ve had several inquiries that I’ve sent along to John G3XYF as the organizer of the event. This has been underway in some fashion since 1957 so isn’t it high time we got in gear on this? Pass this webpage along to other hams whom you might think would be interested.

My church Senior Pastor and Church Administrator quickly button-holed me after the event to please organize it again in 2024. It was a great activity with the stress-to-fun ratio definitely being in the operator’s favor! Food availability tends to draw a crowd…

I’ve included a previous story I published on the Vicksburg (MS) ARC website below so readers can see how it went at my church in Ridgeland, MS for the 2023 event.

Some of our members participated in the first annual special event of CHOTA in the United States. This was at the Highlands Presbyterian Church in Ridgeland, MS on Saturday, September 9, 2023. CHOTA is Churches and Chapels On The Air, an event of the World Association of Christian Radio Amateurs and Listeners. That organization began in 1957 in England by the Huddersfield South Methodist Radio Club. It’s been ecumenical since 1978. (See https://k4fmh.com/2023/07/12/chota-2023/ for details on CHOTA and planning for this event.)

The Jackson ARC managed the Welcome Tent uponr the invitation of event organizer Frank K4FMH and his church administrator, Larnie Shinnick. JARC invited members of VARC to attend, operate and exhibit satellite communications. Eddie Pettis N5JGK was joined by an area ham, Rick Largent N5ZNL to showcase this activity. All area hams were invited to attend the event through the dissemination of an announcement flyer and ARRL MS Section emails.

Four stations were set up to work Phone, CW, FT8, and satellites. The HF stations used wire antennas hung from trees on one corner of the church’s sixteen-acre campus. Stations were limited to these to avoid RF interference. The SSB and FT8 stations each had bandpass filters to help in this regard. VARC member Eddie Pettis N5JGK used his HT and Arrow antenna, as did Rick Largent N5ZNL, to work satellites. Mike N5DU used his Xiegu G90 station at 10 watts to work FT8 on 10 and 15 meters, reaching Europe, South America for several contacts that really excited TV reporter Walt Grayson in his story. Frank K4FMH brought his HF station built into a large Gator Case featuring an Icom 7300, Ameritron amplifier, MFJ ATU, Array Solutions Bandpass System, and BHI DSP speaker. Tom Brown AE5I brought his Yaesu FT-897 transceiver and CW bug where he and Mike Duke K5XU worked the meager options available on a very ragged 40M band. A total of over 100 contacts were made throughout the US as well as around the world. Two SSB contacts were with other activated churches in the US although those in England were not heard here.

The church provided a food truck on site and added ice cream. Both were free to those in attendance. We greatly appreciate Highlands Pres for being such a gracious host for this event! Truly, a good time was had by all in attendance.

The news media was present and gave great coverage of the event, including a front-page story in the Jackson Clarion-Ledger on Monday (see pic). The Clarion-Ledger has a gallery of pictures taken by reporter Ed Inman with a front-page story in the paper’s Monday, September 11th edition. Legendary TV news reporter Walt Grayson of WJTV Channel 12 in Jackson published a video feature story for the Monday evening newscast. Jim Armstrong AK5J said that for as long as he has been a licensed ham operator, he has not seen as much publicity for amateur radio as this event has received.

Operating Patterns Among Canadian Amateurs Report is Completed

It’s taken me months longer than I anticipated but my full analysis of the national survey that the Radio Amateurs of Canada fielded in 2021 is now in completed form. RAC President Phil McBride VA3QR and Regulatory Affairs Officer Dave Goodwin VE3KG are reading it now.

Dave Goodwin had asked me to drop everything and do an extensive analysis of the 2023 RAC survey on amateur call signs for the regulator in Canada. They have published that report and the raw data themselves on the RAC.ca website. I hope they do the same with this one. It reflects RAC’s commitment to transparency in their work as the national organization for amateur radio.

I have placed a March 2024 date on the “final” version after any corrections in the final draft are completed. RAC will publish the report on their main website afterwards. I’ll put a copy at my complementary website, FoxMikeHotel.com, under this link.

There are some very significant findings in this report for amateur radio in Canada. These data are, from my experience, the most detailed measurements of operating activity for a national survey that is publicly known. Alan Griffin, Editor of RAC journal The Canadian Amateur, is interested in my submissions of papers for their consideration. Stay tuned…
