RAC Ontario Sections Bulletin for July 24th, 2021



1. Volunteer Amateur Radio operators to the rescue in Belgian floods

Emily Hough writes in the Crisis Response Journal about the 30 radio amateurs
who were deployed in the provinces of Brabant Wallon and Hainaut following
the flooding in Belgium

Early in the morning of July 16, the Police building in Wavre – including its
Tetra communications system and computers – was left completely underwater.
This antenna is critical for the Astrid national Tetra system, which is used by
firefighters, medics, the police, civil protection, the army and crisis
communicators. There were also had several local electrical blackouts in
Liège, Luxembourg and Brabant Wallon.

The ham radio volunteers came into their own. The emergency number 112
dispatch requested their help and about 30 volunteers were deployed in the
provinces of Brabant Wallon and Hainaut. They connected fire stations,
ambulance stations, hospitals (including medical emergency vehicles),
the main command post in Wavre and 112 dispatch in Mons.

4. Mapping directional Medium Wave transmitters in USA-Canada

If you listen for MW/AM radio stations in the the USA or Canada then you will
surely know that many of them broadcast with directional antennas.

There is now a software tool by Bill Scott WE7W that will map the radiation
pattern of all MW transmitters in North America. Radio Data Medium Wave (RDMW)
will do this for daytime, nighttime and even critical hours. And the radiation
pattern is superimposed on Google Maps so you can scroll around the globe and
zoom in to even see the transmitter masts!

Not only that but RDMW will ray trace from the transmitter to your receiver,
calculating the exact path a signal will take and its great circle distance.
You can even see how much signal is being radiated in your direction and
whether you are likely to hear a particular station.

You can download RDMW for a small admin charge from the Circle's website.
