You HAVE filed your comments on HR 607 ,
haven't you?
BUSTED QSOS
So months with five weekends come more frequently than every 823 years
as suggested in the last issue. Your editor will serve 823 seconds in
the Contest Update penalty box for insufficient skepticism and lack of
due diligence. Five-weekend months do play hob with contest scheduling,
though. (Thanks, Tom N1MM) Also, it was David N6AN (not N6EN) who gets
credit for the California QSO Party item in the previous issue.
(Thanks, Paul N6LL)

==> NEWS, PRESS RELEASES, AND GENERAL INTEREST
We have several new products of interest to VHF+ contesters for the
coming summer VHF+ contest season. First, M2 has a brand-new
solid-state kilowatt 6 meter amplifier, the 6M-1000
. 80 watts of input power
will produce the full output so your all-band radio should be able to
do the job. A 2 meter version is reportedly in the works, as well. At a
slightly lower output power, Kanga US has new
6 and 2 meter converter kits, plus CW source kits for 6 and 2 meters
designed by Rick KK7B. And finally, take a look at the Fall 2010 issue
of CQ-VHF for a 70 cm tracking beacon by WC5Z.
The ill-advised proposal to "re-purpose"
some of the amateur 70 cm privileges is deflecting amateur attention
from another possible use of spectrum for broadband networking. The
LightSquared company is
proposing to place high-power microwave transmitters adjacent to the
GPS downlink frequencies, something that is very alarming to the GPS
community. As hams know well, if strong enough even a perfectly clean
signal will cause overload problems in an insufficiently selective
receiver. With GPS being a key navigation technology this issue bears
watching as it continues to evolve.
Hams should be sure to use their frequency allocations because the
inquisitive souls at Microsoft have devised a system
for measuring whether licensed radio frequencies are being used by
those who own the rights to the spectrum. I wonder if this tool could
be used to find a clear run frequency during major contests? (Thanks,
Bill W7KXB)
NASA has launched a program to develop spaceflight kits for high school
teachers and students to build and fly on sub-orbital flights. As
reported in the 27 March AMSAT bulletin ANS-086.07,
"NASA
says
its Emerging Commercial Space Office (ECSO) is teaming with Make
Magazine , and Teachers in Space
to help develop spaceflight kits that
high school teachers and students can build and fly on suborbital
flights." The rules have been
published by Make and proposals are due by the end of April.
The broadcast band seems to have been around since KDKA
first went live in 1920
but it did not always have its present configuration. On 29 March 1941,
channel assignments underwent a grand shuffle
,
creating clear-channel frequencies and reserving others for local use.
The top end of the "BC Band" moved higher to 1600 kHz, as well.
Pileup! editor, Ilkka
OH1WZ writes to encourage contributions to
this free, on-line talkoo (joint-work) journal. The next issue is to be
released at the end of May - if you have an idea for an article,
contact Ilkka or his co-editors, OH7WV and
OH6KZP . Each issue has hundreds of readers
in the US, Canada, Europe, and beyond!
Another online magazine is ready for your inspection, as well. The
April 2011 edition of WorldRadio Online
magazine is live. Among other
things, well-known propagation author and contester Carl K9LA writes
the "Propagation" column - always a good read. (Thanks, Editor Richard
KI6SN)
This week's Science News included an article
about sunspots, in which it is expected that the cycle will peak on
schedule in 2013 or 2014 and average activity will remain in the
doldrums for a while. It's that darn meridional flow, apparently!
(Thanks, Bob KY7O)
Both Spock (Leonard Nimoy) and Captain Kirk (William Shatner) turned 80
during the past week - do they still blow out candles on those far-off
star dates or just deactivate the photon emitters?
The New York QSO Party has changed some of its rules regarding mobile
operation. Writes sponsor representative, Paul K2DB, "We have decided
that there needed to be more clarification on the Mobile Category. With
research and feedback, we decided that we needed to add another
category to the Class Entries." See the NYQP web site for more
information .
Mike Koss W9SU, owner of Industrial Communications Engineers, Ltd
. (ICE) passed away suddenly this
past weekend. There is no word on the cause or on the status of ICE at
this point - watch the ICE website for more information. ICE was widely
known for its popular products - Mike will be missed. (Thanks, Tim
K3LR)
The Zeroland QSO Party, scheduled for May 7 and 8, has been canceled.
Not to worry, that same weekend is host to the 7th District QSO Party
, the New England QSO
Party , and the Nevada
and Indiana QSO Parties, 14 states worth of
QSO party fun.
Web Site of the Week - The National Institute of Standards and
Technology, Time and Frequency Division is conducting an online survey
of radio users . Many of us rely on
these broadcasts for calibration (and to know when to start mashing the
F1 key!) so be sure to log in and show that the service is appreciated.
(Thanks, Mike W9RE)
WORD TO THE WISE
Frog - from a popular electrical engineering dictionary, "the top of a
tower". Who knew? So I guess we have to put the plastic owl on top of
the frog to get rid of crows and find True North! Be careful when you
are standing on your frog!
==> SIGHTS AND SOUNDSTHE RADIO ASSOCIATION OF ERIE
, NOW IN
ITS 50TH YEAR, WAS FOUNDED BY THIS CARTOON'S CRYSTAL PURVEYOR, FRANK
BLILEY W3GV
. (THANKS,
TIM K3LR)
Ken K4ZW has posted a nice album of photos
from his recent trip to
Mongolia, JT. If you worked JT5DX on the low bands this past season,
here are the antennas responsible. (Thanks, Dave NN1N)
Valery R5GA has been getting good reviews for his score-reporting web
site . He is also collecting links to YouTube videos
about contest operations and they are fun to watch!
A beautiful compilation of time-lapse photography featuring the aurora
borealis by Terje Sorgjerd is on-line for
you to enjoy. (Thanks, John VA7OTC)
==> RESULTS AND RECORDS
The online package of 2010 ARRL CW Sweepstakes results
are now up and ready for
you, including PDF line scores and log-checking reports (LCRs).
(Thanks, ARRL Contest Branch Manager, Sean KX9X)
Next weekend's Montana QSO Party features an
on-line scoring web page. After the contest, upload your contact totals
and multipliers along with your logs and dupe sheets for verification.
Once everything has been uploaded, you'll see your results instantly
displayed. (Thanks, Ken K0PP)
How good were the bands this past weekend? The KL7RA beams were doing
brisk business on wide-open bands in three directions at the same time
from
latitude 60 N. Welcome back spots! (Photo by KL7RA)
The results of the NY QSO Party
are finished and published. From
the same link, you can also link to the certificate winners. (Thanks,
Paul K2DB)
Results of the 2010 MM All America Contest
are online,
including the scores of 1164 participants; 342 from South America and
822 from North America. (Thanks, Luc PW7T)
Pre-publication results for last weekend's RTTY Sprint
are now online as well.
Individual LCRs (Log Check Reports) can be requested by email
. (Thanks, NCJ NA RTTY Sprint Manager, Ed
W0YK)
Bob K0RC reports that he has, "completed the programming for a new
BARTG HF Contest Log Analyzer and posted it to my web site
." The downloadable spreadsheet tool is
based on Excel 2003 but should work with any version, including the
alternate Sun product called Open Office Calc.
OPERATING TIP
If you are a guest operator at a home station, don't forget to say
thanks to the host family along with the ham who invited you! While
they may not have built the station, their hospitality is important to
your success.
==> TECHNICAL TOPICS AND INFORMATION
Thomas NZ4O writes to let us know that, "I have dropped the LF and MF
aspect of my seven day radiowave propagation forecast due to low
demand. In place of it I now produce a condensed version of my HF
radiowave propagation forecast. I publish it every Friday morning at
0000 UTC on my SolarCycle24.org Facebook web page
, my
Solar Cycle 24 web page, and on my HF/6M
Radiowave Propagation Forecast eGroup
on
Contesting.com. It is also published later in the day at eHam.net,
QRZ.com and Southgate ARC. My complete HF/6M radiowave propagation and
lightning QRN forecast is still available on the Solar Cycle 24 web
page in section 3B."
"Hackerspaces" are popping up all over, such as LVL1
in Louisville, Kentucky. The group includes
several hams and has the club call sign N1LVL! Take a look at the web
site for all the projects they have going on, including the launch of a
balloon to Europe! (Thanks, George K5KG)
Paul K2DB has uploaded a video showing how the
CW reverse beacon network works using his remote station. It shows how
quickly he can get to stations with the packet CW skimmer Reverse
Beacon Network. Click on the right side of the home page under Main
Pages on the RDXA Library link, then Tutorials and Presentations, click
on Remote CW Skimmer Demo. When you get on the air on CW and call CQ,
you can run but you cannot hide!
The book "Storage Batteries - Including Operation, Charging,
Maintenance and Repair
"
by G Smith is highly recommended by Frank VK2AKG. It's a good tutorial,
now in its 3rd edition, on how to take care of those expensive backup
power sources!
Tower-mounted standoffs help keep coax from getting caught in a crankup
tower or just hold them away from your tower legs. Bob K6UJ recommends
standoffs from KF7P ,
particularly the curved standoff for supporting a dangling cable.
Here's what a single-point grounding system looks like. This one keeps
George K5KG out of trouble in Sarasota, Florida's frequent
thunderstorms. (Photo by N0AX)
Jim W7RY provides this link to professional grounding guidelines
. He also recommends the
Motorola R56 Site Ground Standards and Tom W8JI's
material on grounding.
Yes sir, yes sir, three bags full - well, most tower bases take more
concrete than that. How many do you need, anyway? Mickey N4MB uses this
simple online calculator
to get the answer. He cautions the user that while almost all the input
values are in feet, the depth is entered in inches!
Base loading an antenna to resonate on 160 meters or 80 meters can be
tricky. Phil AD5X has addressed the subject
from the perspective
of his 43-foot vertical antenna. There's good information in the
article you can apply to many similar needs. (Thanks, Al AB2ZY)
Teflon is not supposed to stick to anything - so how can you glue it or
attach it to something? Lars LA7SL recommends this special adhesive
and David G4FTC the
Loctite products 406 adhesive and 770 primer.
Ulf SM0NOR takes a shorter path and suggests the bondable Teflon sheet
from Small Parts
.
Technical Web Site of the Week - Remember "mill copy" and the
clackety-clack as the typewriter keys hammered out another radiogram?
I'll bet you can smell that typewriter oil right now! Well, that old
manual or electric you just can't quite bear to part with does have a
place in this digital age - but you have to convert it to use USB as
described in this IEEE Spectrum article
about a conversion kit
from hackerspace Hive 76 .
==> CONVERSATION
Radiation and Radio
With so much concern over the damaged nuclear reactors in Japan,
sensitivity to the word "radiation" is very much higher than usual. In
general, the public is not aware of the many meanings of the word nor
are they sensitive to the differences in types of radiation. Since hams
use electromagnetic radiation to communicate, it behooves us to be able
to coherently explain why "our" radiation is OK and not a threat to
others.
Radio waves are non-ionizing radiation
that does not
contain sufficient energy to separate electrons from atoms and create
ions. That effect only occurs at frequencies orders of magnitude higher
than for radio signals. As you learned during your licensing studies,
radio frequency energy only results in thermal (heating) effects to the
body. The amount of heating depends on the frequency and power levels
involved. Radio waves have not been shown to cause biological effects,
such as genetic damage or cancer. Radiation from nuclear sources, such
as radioactive substances, can cause biological effects because it is
ionizing radiation .
Furthering the confusion, the word "hot" is used to refer to both
thermally hot and radioactive materials. Radioactivity can heat up
materials (the inside of the Earth is kept hot from radioactive decay)
but not vice versa. Only ionizing radiation from radioactive materials
has enough energy to cause significant health hazards.
Exposure to ionizing radiation is measured in sieverts - a term
unfamiliar to most people. Because it is an unfamiliar measurement, we
find it difficult to assess the importance of numeric values. Normal
background levels of ionizing radiation are so low that even a small
release of radioactivity can cause a change that sounds alarmingly
high. Here is an excellent chart that
gives some perspective to exposure. The current one-day dose of
radiation near the plants (at the moment) is shown at the left of the
green part of the chart. Additional discussion and references can be
found here in this blog entry
. For those of you
living in the mountains or taking lots of airplane rides, this
information may be a bit of a surprise!
An explanation of permitted versus recommended levels of ionizing
radiation was also discussed in an NPR interview on Mar 21st with Dr.
Harold Swartz, professor of radiology and medicine, Dartmouth College.
A transcript
of that interview is available online and may be of interest in
explaining the relative numbers we are encountering.
Risk from exposure to radiation is not an easy thing to quantify in a
single, brief statement. There are many factors involved and it is rare
that we have all of the data or the expertise to evaluate that risk.
Nevertheless, since we work with "radiation" every time we get on the
air, it's important to be able to help our families and neighbors
distinguish between what does and does not constitute a risk.
