+ HR 607: NPSTC Says HR 607 "Needs to Be Amended"
Read NPSTC's letter to the ARRL, opposing HR 607
as it is currently written,
<http://www.arrl.org/attachments/view/News/57518>here.
The National Public Safety Telecommunications
Council (NPSTC) -- a federation of more than a
dozen public safety communications organizations
-- has gone on record as sharing the ARRL's
concerns regarding HR 607, the Broadband for
First Responders' Act of 2011. The ARRL is
actively opposing the legislation in its current
form because Section 207(d) of the bill --
introduced in the US House of Representatives by
Representative Peter King (R-NY-3) -- calls for
the reallocation of 420-440 MHz for commercial
auction. The ARRL, which is a member of the NPSTC
Governing Board, has assured NPSTC members that
its opposition is limited to Section 207(d) and
that it supports the underlying objective of the
legislation, which is to provide spectrum near
700 MHz for a nationwide interoperable public
safety broadband network. Read more

+ FCC News: FCC Adopts Spread Spectrum Rules Changes
In a Report and Order adopted February 22 and
released March 4, 2011, the FCC eliminated the
requirement that amateur stations transmitting
Spread Spectrum use Automatic Power Control (APC)
to reduce transmitter power. At the same time,
the Commission has reduced the maximum power of a
Spread Spectrum emission from 100 to 10 W PEP. In
March 2006, the ARRL filed a Petition for
Rulemaking, asking that the APC requirement be eliminated.
The R&O explains the Commission's actions this
way: "We believe that these rules changes will
(1) encourage individuals who can contribute to
the advancement of the radio art to more fully
utilize SS technologies in experimentation, and
(2) balance the interests of all users in
mixed-mode and mixed-service frequency bands
until sharing protocols are sufficiently
developed to avoid interference." Read more

+ FCC News: FCC Issues California Man $7000
Forfeiture Order for Refusing FCC Inspection
After a Merced, California man refused to let FCC
investigators inspect his Citizens Band (CB)
radio station, the FCC issued a Notice of
Apparent Liability for Forfeiture (NAL) for
$7000. The Commission found that Ira Jones
"apparently willfully and repeatedly" violated
Section 303(n) of the Communications Act of 1934,
as amended, and Section 95.426(a) of the
Commission's rules by failing to permit the
inspection. Read more

+ Amateur Radio in the Classroom: Middle School
Students to Launch Near-Space Balloon

attempt to launch a near-space balloon later this
month. [Photo courtesy of Bill Richardson, N5VEI]
A group of students from Olde Towne Middle School
( OTMS) in Ridgeland, Mississippi is preparing
for a trip to space -- or as close as they can
get. The OTMS RadioN5VEI] and Technology Club,
along with the school's Science Team, are
planning a near-space balloon launch at 9 AM
(CDT) on March 26 (the date and time are subject
to change depending on weather). The balloon --
nicknamed Titans in Space -- will use the call
sign KC5NXD and is expected to reach an altitude
of 94,825 feet. Read more

+ Propagation: Respected Journal Publishes Explanation for Low Sunspots
An article in the March 3 issue of the journal
Nature purports to explain the extended sunspot
minimum from 2008-2010. According to one of the
authors, Piet Martens, the last time a sunspot
minimum lasted twice as long as usual was around
1913 and before that, 1810. Although solar
activity has increased recently, scientists have
been puzzled by the lack of sunspots from
2008-2010. This quiet period had prevented the
ionosphere from supporting much of the long-range
higher frequency HF Amateur Radio communication
that had been expected during the past few years.

Hints & Kinks : Weatherproofing Your Automatic Antenna Tuner
Geoff Haines, N1GY, of Bradenton, Florida, sent
us this idea for waterproofing your automatic
antenna tuner. Contact Geoff via
<mailto:n1gy at arrl.net>e-mail for more information.
As an avid Amateur Radio operator, I sometimes
use an automatic antenna tuner to operate more
than one band with the same antenna. My mobile
unit uses an LDG RT-11 autotuner to feed a pair
of "Hamstick" style antennas on several different
bands. One antenna covers the lower bands and
another antenna covers the higher ones. An
excursion into operating "fixed portable" with a
telescopic vertical had me looking for another solution.
Figure 1
In order to minimize the coax losses when feeding
a vertical monopole away from its resonant band
it is necessary to reduce the distance between
the tuner and the antenna to a minimum. The use
of ladder line is not feasible when the antenna
is fed almost at ground level. In order to do
this, it is necessary to place the tuner almost
directly at the base of the antenna and thus
reduce the coax run from the tuner to the antenna
to nearly nothing. The coax from the tuner to the
transmitter can then be any appropriate length
since the mismatch has already been corrected.
Owning an LDG Z-100 automatic tuner already, I
looked for a way to mount it at the base of the
antenna and yet protect it from the elements. A
phone call to LDG gave me the necessary
specifications for a 50 foot extension of the
control cable so the only thing left was to find
a workable enclosure for the tuner itself. I
discussed the requirements for such an enclosure
with my spouse, Audrey. Without a word, she
rummaged through a kitchen cabinet and produced a
semi flexible plastic container that had a
snap-on lid and fit my Z-100 and its cables to a T.
I drilled four small holes in one end of the
container into which I fitted two short coax
jumpers, one for the antenna and one for the
radio. I also made up and installed a short
4-conductor cable to connect the stock control
harness to the 50 foot extension. The fourth
opening was used for a similarly short insulated
wire to connect the grounding stud on the Z-100
to the radial system of the antenna. Once these
four cables were in place, I sealed the drilled
openings with hot glue. Silicone caulk could be
used just as easily, provided it will stick to
the container. I did not try that because the hot
glue was at hand so you are on your own there (see Figure 1).
With the jumpers connected to the tuner, the
extension cable and coax were run to the
transceiver and the antenna erected. Now, testing
was in order. The pressing of the TUNE button on
my IC-706MKIIG did exactly what it was supposed
to do. The Z-100 ran through its paces and
signaled a good match. Now if the afternoon
showers come while I am operating "fixed
portable," the only thing I have to worry about
is keeping me and the radio dry. The tuner is
cozy in its own little raincoat (see Figure 2).
Figure 2
Total cost, even if you had to buy the container
new at the discount store, would probably not
exceed $10. That does not include the extension
control cable of course. The container was
already here and I had enough UHF connectors,
coax, wire and weatherproofing on hand for the
project. The only thing I had to buy was the
4-conductor cable and Molex connectors to build the 50 foot extension cable.
This project has enabled me to comfortably
operate "fixed portable" from the beach, at Field
Day and many other events where a vertical was
the only feasible antenna. As long as the
container can handle the physical size of the
tuner with room for the connecting cables, any
automatic tuner could be protected in this way.
Do you have an idea or a simple project that has
improved your operating? Maybe you've taken
something commonly found around the home and
developed a ham radio use for it? Why not share
your hints with fellow hams in "Hints and Kinks,"
a monthly column in QST. If we publish your hint,
you will receive $20. Send your hints via e-mail
to h&k(at)arrl(dot)org or to ARRL Headquarters,
Attn: "Hints and Kinks," 225 Main St, Newington,
CT 06111. Please include your name, call sign,
complete mailing address, daytime telephone number and e-mail address.

Solar Update
The Sun, as seen on Thursday, March 10, 2011 from
<http://sohowww.nascom.nasa.gov/data/realtime/realtime-update.html>NASA's
SOHO Extreme Ultraviolet Imaging Telescope. This
<http://soi.stanford.edu/>MDI (Michelson Doppler
Imager) image was taken in the continuum near the
Ni I 6768 Angstrom line. The most prominent
features are the sunspots. This is very much how
the Sun looks in the visible range of the spectrum.

"<http://www.youtube.com/watch?v=-ZFLKXINNns>Fun,
fun, fun in the Sun, Sun, Sun" Cook, K7RA,
reports: Solar Cycle 24 continues to ramp up at a
quickening pace. The average daily sunspot number
this week was more than double the value of the
week before, rising from 50.9 to 114. The average
daily solar flux rose 44 percent, from 96.8 to
139.4. All this week through Tuesday, the sunspot
numbers and solar flux kept rising and beating
old numbers, and we had to look further and
further back into Solar Cycle 23 to find
comparable conditions. On Tuesday, March 8, the
daily sunspot number was 137. The last time the
daily sunspot number was higher than this was
July 7, 2005 when it was 149. Twice this week,
the 10.7 cm receiver at Penticton was overloaded,
swamped by energy from a solar flare and the
daily solar flux value had to be estimated. On
March 7 and 8, the noon solar flux readings were
938.6 and 166.7, and they were corrected by NOAA
to estimated values of 153 and 155. The estimated
flux level of 155 was the highest since July 23,
2004, when the solar flux was 165. Predicted
solar flux for March 10-17 is 150, 145, 140, 140,
135, 130, 125, 105 and then 100 on March 18-21,
then going below 100 until April 2. The predicted
planetary A index for March 10-11 is 22 and 18,
then 5 on March 12-21, 7 on March 22-23, 5 on
March 24-26, then 7, 7, 19 and 7 on March 27-30.
Note the high predicted planetary A index on
March 10-11 of 22 and 18. This is because of
recent solar flares, and the disturbance will
probably affect signals traversing a polar route.
Look for more information -- including
propagation reports, as well as a critical look
at last week's report of a 2 meter FM signal from
South America, reportedly monitored in North
Carolina, more than 4700 miles away -- on the
ARRL website on Friday, March 11. For more
