  The military renaissance in high frequency communications
Posted by: VA3KOT John - 2020-09-24, 21:19:36 - Forum: Announcements, Ideas, Opinion - No Replies

Military use of HF has been superceded by satellite comms which is less vulnerable to solar activity. Unfortunately, satellites are highly vulnerable to anti-satellite warfare as this article explains. So now the European military - and presumably others too - are getting back into HF. Good article, very interesting especially in how the military is using weak signal technology, high data rates and Automatic Link Establishment (ALE) to get the most out of HF despite possibly adverse propagation conditions.

  Fox Hunting 101 - Part 3
Posted by: VA3KOT John - 2020-09-21, 19:01:17 - Forum: Antennas, Operating - Replies (1)

Cross Polarization

The key factor in fox hunting is reducing the received strength of the signal from the hidden transmitter in order to enhance the ability to find a directional null. Strong signals seem to come from every direction but when the signal is weak it is easier to hear a stronger signal coming from one direction. Dave, VE3WI, has already suggested using the body shielding technique which is a very valid and effective way to achieve signal attenuation. By holding our HT close to our body we can shield signals coming from every direction except straight ahead.

There is another technique we can also use, perhaps in combination with body shielding, to reduce received signal strength. In our Basic licensing courses we learned about cross-polarization. If the transmitting antenna is vertically polarized, a horizontally polarized receiving antenna will pickup a significantly reduced signal. In theory cross-polarization loss is infinite but, in practice, reflected signals from multiple angles are also picked up. So if the transmitting antenna is vertical, holding our HT antenna horizontally will reduce a weak signal a little more.


Why don't we get a group of GBARC members together to do some local fox-hunting. Experienced fox-hunters can help train newcomers in the techniques used. A typical event lasts a couple of hours and ends when a hunter successfully tracks down a hidden low power transmitter. Please reply to this post if you would like to know more, or get involved.

RAC Ontario Sections Bulletin for September 19th, 2020

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

NATIONAL/INTERNATIONAL NEWS

1.  Beginners CW course now full - Look for additional offerings in January.

If you would like to be placed on the waiting list for future CW courses please
send an email directly to Tony VE2KM @ YnotSailing.com with “RAC CW Course” as
the subject line.

2. Ham radio channels designated for Wildfires and Hurricane Sally

ARRL reports that two 5-MHz interoperability channels have been designated for Wildfires
and Hurricane Sally response

The Federal Emergency Management Agency (FEMA) has announced that two 60-meter channels
have been made available, as necessary, for interoperability between US Government stations
and US amateur radio stations involved in emergency communications related to the wildland
firefighting response in California, Oregon, and Washington, and to Hurricane Sally.

These interoperability channels will remain active until the need for these channels
no longer exists:
• Channel 1 — primary voice traffic 5332 kHz channel center, 5330.5 kHz USB voice
• Channel 2 — digital traffic 5348 kHz channel center, 5346.5 kHz USB with 1.5-kHz offset
    to center of digital waveform.

3.  Ham radio save lives during wildfires and hurricanes

In Wired, Jaime Stathis writes there's no better time to be an Amateur Radio Geek

"The most important component of staying safe during an emergency is the ability to give
and receive information. When the power goes out — which it often does — the internet
doesn’t work and cellular networks crash with increased demand. In Northern California,
we often have our electricity cut to prevent fire during high-risk times, leaving millions
of customers in both metaphorical and actual dark."
"Although I spent most of my life thinking amateur radio was for geeks and grandparents,
I now sit with a friend for twice-weekly check-ins with the local amateur radio club.
Amateur radio operators not only help themselves, but in emergencies they deploy to assist
organizations like the Federal Emergency Management Agency (FEMA), Red Cross, and local
public safety offices communicate and coordinate with the public, and with each other."

4.  The sun has begun a new solar cycle.

The sun is officially nine months into a new solar weather cycle, scientists have
confirmed, and it will likely look much like cycle 24, which ran from 2008 to 2019.

Scientists predict that cycle 25, will peak in July 2025 (Peak Sunspot Number of 115)
but will generally be a less active cycle, quite similar to solar cycle 24, which
ended in December.

Monitoring solar activity and making reliable predictions about upcoming solar cycles
will be particularly important as astronauts once again venture out beyond the
protection of Earth's magnetic field.

NASA is working to send astronauts back to the moon in the coming years, with humans
stepping foot on the moon for the first time in five decades in 2024, the year before
the solar cycle's predicted peak.

  POTA Activation #2
Posted by: VA3KOT John - 2020-09-17, 20:59:41 - Forum: Antennas, Operating - Replies (6)

This Parks On The Air program is getting to be more fun than a barrel of monkeys. XYL, dog and I spent 3 days in our trailer up at Grundy Lake Provincial Park (85km south of Sudbury, off highway 69) this week. I took my portable kit comprising a Yaesu FT-891, homebrew L-match tuner and my End-Fed-Half-Wave antenna (electrically a half-wave on 80m but physically shortened with a loading coil).

I operated in two sessions, one on Monday afternoon and again on Tuesday afternoon. The objective was to get 10 contacts within the same UTC day (i.e. between 00:00 and 23:59UTC). The fun thing about POTA is that once you get "spotted" you get a pile-up of "hunters". It only takes a couple of CQs, if you are a CW op, to get spotted. The Reverse Beacon Net (RBN) spot is picked by POTA and re-spotted to the POTA site. That didn't seem to work on the first day, but fortunately Grundy Lake Provincial Park is close to the highway so I used my cellphone to self-spot directly to the POTA site.

It was quite cool in the park so I was operating from inside my trailer and putting out 100 watts. The signal reports I received were generally better than my received signal reports. Maybe the FT-891 sensitivity isn't so good, or my antenna (up 30ft in a tree) didn't have good ears. Anyway, I logged enough QSOs each day to qualify for the activation so I was very pleased with that. My log is attached below.

2. Brazil proposes end of all amateur radio exams

ANATEL, the Brazilian National Telecommunications Agency, recently published a public
consultation, CP65.
In their website, LABRE, the Brazilian Amateur Radio League, was surprised by the CP65 proposal
- the extinction of the COER (amateur radio certificate) exam for all classes and replacement by
free access to initial class C, as is done today with the Citizen's Band, as well as access to subsequent
classes B and A upon presentation of the Certificate of Technical Course and Graduation in
Telecommunications, respectively, or minimum stay of 3 years in each class.
In addition, the aforementioned proposal suggests ending the rule of different prefixes for
each of the States of the Federation, remaining only the prefix per class and there would no
longer be any special callsigns.
The proposal, in addition to going against what is consensus in the international regulation related to
the Amateur Radio Service, is absolutely contrary to the LABRE's thinking with regard to the minimum
requirements to be a radio amateur and also does not match ANATEL's request for support from LABRE
in the revision of amateur radio regulations in Brazil.
For further clarification on the subject, LABRE has already requested a meeting with ANATEL,
which will be scheduled soon.

4.  FMH Portable Operations Challenge allows 'Patio Portable'

The steering committee of the upcoming international Fox Mike Hotel Portable Operations Challenge on
October 3rd & 4th wish to make it clear that operation as a portable station from your back yard, garden
or indeed patio, using the equipment that you would otherwise have taken portable for the challenge,
is allowed and will be included in the portable station classification of the contest.
No existing home antenna systems may be used - so the operator will need to set up equipment he or she would have been using portable during the challenge weekend. The only permanent home infrastructure that can be
used is electric power - everything else must be set-up new on the patio / in the garden.
The call sign will be the home call sign with no "/P" suffix but the station class given in the exchange must be
given as P.   For full details please refer to https://foxmikehotel.com/challenge/
