ARLP052 Propagation de K7RA

No sunspots over our reporting week, December 20-26, so compared to
the previous seven days average daily sunspot number declined from
3.4 to 0.

Average daily solar flux was 70, down slightly from 70.4.

Average planetary A index increased from 4.1 to 4.3, while average
mid-latitude values went from 3 to 4.

Predicted solar flux is 69 on December 28 through January 4, 72 on
January 5, 70 on January 6-13, 69 on January 14 through 18, 71 on
January 19-26, 72 on January 27 through February 1, 70 on February
2-9, and 69 on February 10.

Predicted planetary A index is 8, 12, 8, 12 and 10 on December 28
through January 1, 5 on January 2-4, then 10, 10 and 8 on January
5-7, 5 on January 8-12, 8 on January 13, then 5, 5 and 12 on January
14-16, 5 on January 17-19, 8 on January 20, 5 on January 21-23, then
8, 12, 10 and 8 on January 24-27, 5 on January 28-29, 10 and 12 on
January 30-31, 10 on February 1-2, 8 on February 3, and 5 on
February 4-10.

Geomagnetic activity forecast for the period December 28, 2018 to
January 23, 2019 from F.K. Janda, OK1HH.

“Geomagnetic field will be:
Quiet on January 10-12, 22-23
Quiet to unsettled on January 13, 19
Quiet to active on December 28, 31, January 1-2, 9, 20
Unsettled to active on December 29, (30,) January (3-5,) 6-8, 14, 17-18, 21
Active to disturbed on January (15-16)

“Solar wind will intensify on December 28-31, January 1, (3-4,) 5-7,
(8, 13-14,) 15-16, (17-19)

“Parenthesis means lower probability of activity enhancement.”

Al Brown, W1VTP of Manchester, New Hampshire sent this email:

“I manage The Vermont Net on 3975 kHz at 2330 UTC. We have been
having propagation issues since November. I recall similar
difficulties back in 2009 and it straightened out somewhere around
mid Feb 2010. I have used the foF2 map (see
https://www.sws.bom.gov.au/HF_Systems/6/5) put out by the Australian
government for some time but it doesn’t always make sense. I
understand that amateur radio operators are mostly interested in DX
(make that ‘long haul’) propagation. But some of us have regional
nets with average distance of 100 miles.

“Do you have any other explanation where I could predict propagation
for a given night? I’m thinking it may have something to do with a
disturbance in the magnetosphere and the effect of coronal dark
holes when pointed at earth but do not have any reference material
to back that up.

“The closest thing I have is that foF2 map but it doesn’t always
work out that way.”

We covered the same issue in this bulletin in the past, but I can’t
locate the bulletin. This happens when sunspot numbers are too low
to support local propagation on 75-80 meters. We might think of
local nets in that part of the spectrum using groundwave
propagation, but for wider coverage beyond line-of-sight it depends
on high angle signals reflecting back from the ionosphere.

This is why NVIS antennas are useful (see
https://en.wikipedia.org/wiki/Near_vertical_incidence_skywave ).

When I asked K9LA about this, Carl responded, “The MUF can be low
enough that high angle 75m/80m signals go thru the ionosphere at
night during the winter (especially at solar minimum). As you know,
with high angle signals, the MUF is pretty close to foF2 – so foF2
could be a good indicator. You may have to modify foF2 a bit based
on distance. And having an ionosonde near you would be best.”

Here is a site with a number of links to ionosondes:

http://giro.uml.edu/IonogramMovies/

Note the link to Millstone Hill, which may be the closest ionosonde
to W1VTP.

Click on the MHJ45 link.

Clicking on that link goes to a page with ionosonde data from 1992
to 2018.

If you click on 2018, it will take you to links for all 12 months of
the year. Click on December, and click on the latest date, and you
will see links for every 15 minutes of the day. I clicked on the
latest one, which was for 0930 UTC at the time. It showed the foF2
value at 2.45 MHz, which is too low to support local high angle
coverage for 75 meters, but 160 meters should work.

I see there are links to ionosondes at Wallops Island (Virginia),
Boulder (Colorado), Eglin AFB (Florida), Idaho National Labs and
many other locations around the globe.

K9LA suggested that the net could QSY to 160 meters when this
happens.

The ionogram I am looking at currently can be seen here:

https://bit.ly/2CBuC5A

You see MHz on the X-axis and timing on the Y-axis. A chirp signal
is swept across the HF spectrum, and the wispy looking echoes are
what comes back. The various timings reveal the elevation of ionized
layers.

This tool should help to get a handle on this propagation problem.

From 0000-2359 UTC on January 1, is the annual ARRL Straight Key
Night operating event:  http://www.arrl.org/straight-key-night

Dr. Tamitha Skov put out this video shortly after Propagation
Forecast Bulletin ARLP051 was released last week, so this is a
little out of date:

NAQCC March 2018 Newsletter

Comment:

One of my favorite Amateur/Ham Radio publications is the NAQCC Newsletter issued by the North American QRP CW Club.  The issue is full of intriguing construction projects, technical topics, contest information, and operating suggestions. Even if your interests don’t fall into the QRP zone, you’ll find some fascinating articles to stimulate your brain.

NAQCC President Paul Huff (N8XMS) and his volunteer crew do an excellent job of portraying Amateur/Ham Radio in our often confusing world.  Before I list some of the topics discussed in the current issue, I thought Paul’s thoughts on the mission and purpose of the North American QRP CW Club would be appropriate:

“STATEMENT OF PURPOSE
From NAQCC President Paul Huff, N8XMS
Amateur radio has something for everyone. SSB, FM, AM, the digital modes, and QRO power levels all
have their place in this great hobby and we certainly recognize the importance of these modes as well
as the enjoyment that they give to many. But for a growing number of hams the challenge of “doing the
most with the least” makes QRP (and QRPp) CW operating the greatest thrill available in amateur radio,
and the North American QRP CW Club exists to promote this exciting facet of the hobby. As part of our
focus we also encourage, but do not limit operators to, the use of simple wire antennas.
The NAQCC provides numerous opportunities for hams to enjoy QRP/CW operating. For contester
types we have a popular monthly 2-hour sprint that runs at relatively low CW speeds and at a fairly
relaxed pace. Three special sprints also take place during the year for 160-meter and QRPp operators.
For a month-long activity we offer our members a Monthly Challenge that can be anything from forming
a list of words from the calls of stations worked, to making a prescribed number of contacts using homebrew
gear. There is also an extensive awards program to recognize the significant QRP/CW
accomplishments of our members.
We also serve as a resource for people who are just getting started in QRP and/or CW. Our slow-speed
CW nets are a great place for beginners to practice Morse code under real on-air conditions. Beginners
will also find a wealth of helpful information on our club website and we are more than willing to try to
answer any questions about QRP and CW that you might have. An extensive monthly newsletter is
filled with useful projects and news from fellow QRPers.
A number of local NAQCC Chapters offer opportunities to get together for in person socializing and
QRP/CW activities. Portable operations are especially popular with the local chapters.
Whether you are a veteran ham radio operator who is looking for a new challenge in the hobby, or a
beginner who is intrigued by the possibilities of QRP/CW communication, we cordially invite you to join
us. Membership is free and the benefits and fun are significant.
The North American QRP CW Club was founded in 2004 by
WY3H and K3WWP and now has over 9000 members world
wide. Membership is free and anyone interested in CW/QRP
operating is welcome. Complete information about the NAQCC,
including a membership application, activities schedule, and useful
resources, can be found on our website at http://www.naqcc.info/.
Inquires can also be sent to
Club President Paul Huff, N8XMS
9928 Eckles
Livonia, MI 48150

NAQCC membership is free.

ARRL at 100: A century of Ham Radio


Accessed on 14 March 2018, 1559 UTC, Post #493.

While I was cruising the web for some new antenna ideas, I came across this video produced in 2014 for the 100th anniversary of the ARRL.  Although the video is a few years old, the message is still worth seeing.  Narrator Becky Schoenfeld (W1BXY) does an excellent job of explaining the origins, mission, and projects of the ARRL.  I would like to operate W1AW one of these days–it would be an experience of a lifetime.
