RAC Bulletin for August 13, 2022

Official Bulletin Station for Radio Amateurs of Canada
with this week’s bulletin.


1. MFJ to Celebrate 50th Anniversary

MFJ Enterprises, an amateur radio electronics manufacturer and retailer, will celebrate 50 years
in business this October. Martin Jue, K5FLU, founded the company in 1972 after building a CW
filter kit that sold for less than $10. Since 1990 the company has made five acquisitions, including
Hy-Gain and Cushcraft antennas.
MFJ Customer Services and Public Relations Manager Richard Stubbs says the company continues
to grow with the popularity of amateur radio and currently manufactures over 2,000 products. “I’ve
been with the company for 28 years,” said Stubbs. “Amateur radio continues to grow worldwide.”
Jue graduated from Mississippi State University with a bachelor’s degree in electrical engineering, and
he earned a master’s degree in electrical engineering at Georgia Institute of Technology (Georgia Tech).
He served as a professor of electrical engineering at Mississippi State University from 1972 until 1979,
but abandoned his doctorate in 1977 because of MFJ’s growth.
Currently, because of COVID-19 concerns, the company does not have any plans for a special event
to celebrate the anniversary, although Stubbs said that may change in the months ahead.

2. QSO Today Virtual Ham Expo – Sept 17-18, 2022

The First QSO Today Virtual Ham Expo was in August 2020 where over 15,000 amateurs
attended on the Expo weekend, attending on their computers over the Internet instead of
in-person. Over 80 presentations were made, with live Q&A on Zoom webinar, and attendees
could come back over a 30 day on-demand period to view the presentations that they missed.

We discovered something unique in August 2020, from surveys that we made following the expo.
Sixty percent of the 15,000 attendees, almost 9000 hams do not go to live expos, preferring to
stay at home. The Covid-19 Pandemic has made this all the more important.

Four QSO Today Virtual Ham Expo have been produced over the last two years. We come
back twice a year to make the best ham radio educational event.
Tickets for September are now on sale.

3.  RTTY turns 100

On August 9, 1922 a text was typed in an airplane and simultaneously printed out at a ground station
With this experiment, the US Navy Department gave the telex procedure wings – exactly 100 years ago.
From now on it was possible to transmit texts wirelessly at a speed of up to 100 words per minute. The
ministry immediately pushed for messages to be made available in the opposite direction, namely from
the ground to the plane. It was the birth of radio telex – “RTTY”.

After the Second World War, the first telexes came into the hands of radio amateurs in the USA, who
then modified their transmitters for frequency shift keying (FSK). RTTY had now also arrived in the
amateur radio service.

With the advent of personal computers at the beginning of the 1980s, they replaced the previously
widespread electromechanically generated RTTY with very simple RTTY programs. With the
introduction of digital technology and the development of new types of transmission such as PSK31
and later FT8, RTTY has lost its previous importance in amateur radio.

in August 1922 to receive typed radio messages from a naval aircraft, see

4. Free PDF G3XBM Project Scrapbook

If you need inspiration for your next project you might find it in this free PDF.
The ‘book’ is totally free and hopefully you will find some ideas here. Building and
experimenting is not expensive and great fun.
