RAC Ontario Sections Bulletin for January 11, 2020

This is V__3____, Official Bulletin Station for Radio Amateurs of Canada, with this week's bulletin

NATIONAL/INTERNATIONAL NEWS

1.  Bushfire Emergency Communications Advice (Wireless Institute of Australia)

Bushfires continue to rage widely across large areas of Australia with both loss of life and property.

The WIA has been advised that there are major outages of telecommunications in areas impacted by the
bushfires either currently or expected to occur in the near term. This disruption advice, at the time
this news item was composed, currently applies to areas of NSW and VIC states - but this may change.

The WIA kindly asks Radio Amateurs to monitor the IARU EMCOM Region 3 HF frequencies whenever feasible
during the bushfire emergency. As an IARU member society, the WIA has adopted these recommended
frequencies: 3.600 MHz. 7.110 MHz. 14.300 MHz. 18.160 MHz. 21.360 MHz.

These "Centre of Activity" frequencies are not spot frequencies or net frequencies. They are recommended
as starting points for emergency traffic which may extend ± 5 kHz near the designated centre frequency.

Emergency Communication is one of the three main reasons Radio Amateurs have access to RF Spectrum.
Please assist if and when you can by keepling these frequencies clear of interference.

3.  Winter Field Day 2020 is January 25-26

Winter Field Day, sponsored by the Winter Field Day Association (WFDA), will take place over the
January 25-26 weekend.
The Winter Field Day Association (WFDA) is a dedicated group of Amateur Radio Operators who believe
that emergency communications in a winter environment is just as important as the preparations and
practice that is done each summer but with some additional unique operational concerns. We believe
that maintaining your operational skills should not be limited to fair weather scenarios.

Preparedness is the key to a professional and timely response during any event and this is what
local authorities are expecting when they reach out to the emergency service groups that
offer their services. We are sure you will find this event a pleasant change and challenge
to that of a normal summer time Field Day.

4. Grey Line Propagation

Grey line propagation provides surprisingly long distance radio communications at dawn and dusk
when other forms of ionospheric propagation may not be expected to provide signal paths
of these distances.
This mode of propagation is widely used in ham radio, often providing signals from the other side
of the globe at these times.
When listening to signals coming in via grey line propagation, it is particularly interesting to
hear how the signals come up in strength and then fall away again. It is also possible to hear
how the propagation moves as the dawn or dusk line changes and first stations in one area and
the next are making contacts via the grey line.

Find out how grey line propagation arises and how it can best be used.
