  A New Non-Commercial FM Station for San Diego:
  KNSJ, Descanso, 89.1 MHz

  A new non-commercial educational FM station is being born.
KNSJ, Class B1, 89.1 MHz, Descanso, will serve the greater San
Diego area with a fringe (less than 60 dBu) signal, and pre-
liminary listening tests indicate that their transmitter on
Monument Peak "gets out" and makes itself heard in some
highly populated areas.

  Following is a letter from Martin Eder to tell us more
about this new venture.  Mr. Eder is Director and Treasurer of
Activist San Diego, permittee of KNSJ, according to their CP
application that is viewable at the following URL.

  CGC wishes KNSJ the best of success!

  KNSJ(FM) - Solid progress and (finally) on-air testing

  "We will give The CGC Communicator a little scoop for your
final May 2013 issue!  You can be the first to report that KNSJ
89.1 FM will be testing its signal next week after a six-year
effort to get on the air as San Diego's the newest public public
radio station.  We will be an educational, listener-supported
radio station.  We expect to have FCC approval within a couple
of weeks.  Our tower is up on Monument Peak at 6200 feet and
our city of record is Descanso, CA.  In tests the last 2 days
we were delighted to be able to pick up a good signal, while
driving around in all of central San Diego from La Mesa to Ocean
Beach, from Highway 52 in the north to the border of San Ysidro.
By Monday we should be testing the reach of KNSJ's signal in
East County and Imperial Valley.  Early estimates are that
KNSJ 89.1 FM will have a potential of more than 1 million
listeners in the 40 to 60 DB coverage area.  We will have
potential listeners in Mexico as well.

  "At this point KNSJ is a 100% volunteer organization
developing a community radio model of news and public affairs
along with many syndicated programs from nonprofit news outlets
and organizations.  What has been most impressive is that this
full power FM station was put on the air by sheer will power.
Since getting our construction Permit from the FCC, KNSJ got
virtually no grants or outside funding.  Our fundraising efforts
resembled bake sales more than cocktail parties.  Individual
donors and public events raised the $40,000 necessary, along
with literally 1000 hours of volunteer labor.

  "Our doors are open!  Join us!  --  Our doors are wide open
to radio enthusiasts that are surely among The CGC Communicator's
most consistent readers.  While some of us have backgrounds in
public radio, public TV and other media journalism, we lack
people with a multitude of journalism, radio skills and
programming ideas.  We would welcome an appeal in The CGC
Communicator's last newsletter to have people give us a call,
if they would like to get involved on the ground floor of this
new grassroots, community venture.  We have regular meetings
that are open to supporters on the first and third Thursdays
at 7 PM at 4246 Wightman St., San Diego 92105.  Radio enthusiasts
or any interested party can call us at 619-283-1100 or email us
at info (at) KNSJ.org and find out more about our project at
www.KNSJ.org ."

  Thank You

  Thanks to the many of you who have taken the time to thank
us for the CGC Communicator newsletter.  It is gratifying to see
so many responses.  Wish we had the time to answer each and every
one.  Rest assured that all letters were read by the Editor.

  As we've explained (CGC #1200), this is not necessarily the
end of the Communicator, but after 40 years of publication it's
time to take a little break.  Everything else at CGC remains
open for business as usual.

  Finally, just a quick note to say that our new newsletter
address [editor (at) cgccommunicator.com] is not currently setup
to receive e-mails.  It is intended as an address for sending
e-mails to subscribers should we resume publication.  Please
continue to use the [cgc (at) cgc333.connectnet.com] address
for now if you want to contact us about the newsletter.  That
address should remain operational until Wednesday, May 29, 2013.

  Thanks!

  High Standard Off Topic Material

  A computer guru at Southern California Edison ("SCE")
was casting about Google to see what else the initials "SCE"
might stand for, and lo and behold a remarkable short story
and film about Apollo 12 was uncovered.

  Seconds after liftoff on man's second attempt to set foot
on the moon, the Apollo 12 rocket was hit by lightning --
twice -- and "all he!! broke loose."  Inside the space capsule,
flight data on the display screens was lost, a ton of alarms
flashed and telemetry to Earth became instantly indecipherable.
The mission would have to be aborted.

  Fortunately, one person knew exactly what to do.  You
can read about the heroic effort that saved Apollo 12 and
relive the critical moments by viewing a short video posted
at the Web address below.  You will also discover the alternate
meaning of "SCE."

  Many of us have managed to "save the day" by knowing just
what to do in an emergency, so this story will undoubtedly hit
home.  Don't forget to watch the video.  This is an amazing
and inspiring event -- and a great alternate use for the
initials "SCE" that will last forever.

  The CGC Communicator Goes on Sabbatical

  The CGC Communicator is taking an extended sabbatical after
40 years of publication.  Forty years seems like a good round
number for taking a little break, and the circuit disconnect order
from XO/Concentric/Connectnet ("Connectnet") provided the perfect
catalyst for stepping back and taking a closer look at what we
have been doing.

  As most of you know, the circuits used to upload our news-
letter are being dismantled by our Internet Service Provider,
Connectnet.  They have given us an official decommissioning date
of Wednesday, May 29, 2013, at which time we will also lose access
to their newsletter server that has allowed mass mailings.  We
plan to publish at least one more newsletter before the circuits
are dismantled and that newsletter will cover local FCC
Applications & Actions.

  During our time out of print -- which might even span a
number of months -- we will consider whether to resume publication
in light of so many other relevant sources of information being
available on the Internet today.  If we decide to resume publi-
cation, a new means of distribution has already been wired-up
and we plan to mail newsletters from this e-dress:

  editor (at) cgccommunicator.com

  If you need to white-list the new address, please do it now.
Just reassemble the disguised address above by replacing the
" (at) " portion with the @ symbol.

  During our time on sabbatical, our consulting office and
frequency and spectral lab will remain open for business as usual
and we will communicate directly with our consulting clients when
we find news items of unique importance.  Our consulting office
has a separate computer system that will not be affected by the
Connectnet disconnect.

  Special thanks to Steve Blodgett of Earthsignals for
developing the Tech Letters Website to support our publication
(Tech Letters is continuing to accept postings), to Bext Corp.
for archiving our e-newsletters, and to you, our readers, for
feeding us fascinating stories and URLs.  It's been a great
ride, and we are anxious to see what the next 40 years will
bring, Lord willing.

  Where to Find Key Information

  While the CGC Communicator is on sabbatical, you may like to
use the same professional publications we use in compiling our
newsletter each week.  Those publications include:

  o  FCC Daily Digests.  The Digests contain links to official
  FCC news items including call sign changes and broadcast appli-
  cations and actions:
  http://transition.fcc.gov/Daily_Releases/Daily_Digest/2013/dd2013.html

  o  Enforcement Bureau Field Notices.  This is where Notices
  of Violation and Notices of Unlicensed Operation are published.
  The second URL takes you to Enforcement Actions where the pedal
  meets the metal:
  http://transition.fcc.gov/eb/FieldNotices/
  http://transition.fcc.gov/eb/rfo/ActAct.html

  o  Radio World NewsBytes.  This daily publication is, in
  our opinion, the single best source for daily FCC and industry
  news.  Important TV items are often mentioned.  NewsBytes is
  like the CGC Communicator but on a national scale and broader
  in scope.  Anyone can sign up under the "Subscribe to Email

  The Great KBRT Arc-Over

  No matter how much advance planning and expertise are
involved, the unexpected sometimes happens at a new transmitter
plant.  Murphy lives, but fortunately not for long in this case:

  The tower-to-guy wire insulator arc-over at the new KBRT(AM)
transmitter site (mentioned in CGC #1200) has been thoroughly
investigated.  The worst-burnt fiberglass rod/insulator is
pictured at the first URL below.  No insulators other than those
on the top two levels of the high-power tower (#3 SE) showed
any signs of damage during a field inspection.

  KBRT has doubled up the top two levels of insulators on the
affected tower, and corona rings are being installed this week
on the top three levels of guys to prevent future damage.  See
the second URL for a photo of all the top level insulator rods
removed from the high power tower.  The insulator that severely
arced-over became a carbon resistor and therefore a dummy load
of sorts.  The thoroughly burnt fiberglass rod is really
something to behold.

  Thanks to skilled radio frequency engineers, problems
like these are quickly addressed and brought under control.
It wasn't that long ago that the nature of electricity
wasn't even understood, much less controlled.  Much has
been accomplished.

  A New Chairman, a New Era

  As predicted, president Obama has announced his intention to
nominate wireless telecom and cable executive Tom Wheeler as the
next FCC chairman, and designate Commissioner Mignon Clyburn to
the role of Acting Chairwoman once current Chairman Julius
Genachowski steps down.

  FCC News Briefs

  o  The FCC will consider adopting receiver standards.
  While some believe this proceeding was in part devised to
  save LightSquared, the results could lead to a more efficient
  use of the electromagnetic spectrum overall but probably with
  some financial impact on consumers:
  http://tinyurl.com/ReceiverStandardsConsidered

  o  The FCC proposes to expand the availability of in-flight
  broadband for airline passengers:
  http://tinyurl.com/InFlightBB

******************************************************************

  LightSquared Reincarnated

  The FCC recently said LightSquared could temporarily use
1675-1680 MHz to test whether its mobile network can coexist
with government use of that spectrum.

  In contrast, LightSquared said the temporary usage will
test whether NOAA's meteorological operations can be moved to
a different band of spectrum, if LightSquared uses its current
band (whatever that means).

  Sounds like some investigative reporting is needed to
determine if the FCC is once again showing unusual favoritism
toward LightSquared.

  Illicit Prison Communications

  Promoting technological solutions to combat illegal cell
phone use in prisons can save lives and protect prison workers,
other inmates and the general public.

  There are three basic methods to accomplish this goal:
(a) electronically determine the positions of any unauthorized
phones and send in the guards to confiscate the phones, (b) set
up a "managed access or detection system" to block unauthorized
equipment use, or (c) send out jamming signals to block all
phones all the time, including phones owned by prison staff.

  o  EMI standards were set for the LA Metro light rail lines
  according to the IEEE.  However, there is no indication in this
  paper's abstract that the FCC-based RFI limits were met, meaning
  that broadcast (and other) radio signals could get clobbered
  (we know that some AM interference is in fact occurring):
  http://tinyurl.com/LA-Metro-LightRailEMI

  o  As one reader commented on the Metro Gold RFI, "...I hope
  that the FCC will come down hard on the issue [of protecting
  AM broadcast radio].  After all, it is the FCC's responsibility
  to protect this spectrum from abuse."

  In the interim, if the courts don't stop Aereo from putting

******************************************************************

  NAB SHOW -- ANOTHER SUCCESS STORY

  NAB reports exhibit space grew nearly 10 percent over 2012.
The event comprised 1,600 exhibitors spanning 900,000 net square
feet of exhibit space, up from 815,000 net sq. ft. in 2012.

  Total registered attendees: 92,414
  (of which 24,461 were international attendees)

  Countries represented: 155

  The 2012 NAB Show final attendance was estimated at 91,565.

  As usual, we will let the trade press do the heavy lifting
with stories on the convention and confine ourselves to making
just the few remarks below.

******************************************************************

  A PUSH TO TURN OFF AM ANALOG AND GO ALL-DIGITAL

  Glynn Walden (and Ben Downs) pushed hard at the NAB Show
for the FCC to establish an "AM Sunset and All-Digital Sunrise"
date for the AM broadcast band.  They also want the FCC to mandate
that all radio receivers sold in the U.S. have all-digital
receiving capability built-in (for HD Radio of course).  Not
a word was said about testing DRM or any other all-digital
broadcasting technology.

  What these gentlemen failed to say is that the AM band is
already partially digital -- especially in major markets --
and the public isn't demanding digital receivers.  So now they
want the FCC to force digital receivers on everyone -- a very
sweet deal indeed for iBiquity, the parent of HD Radio.

  We appreciate that Glynn Walden believes 110% in AM digital
broadcasting.  His heart is in the right place.  However, the
AM HD technology currently deployed by iBiquity is seriously
flawed -- as we have said repeatedly -- and helps contaminate
the AM band.  Glynn even mentioned the self-inflicted inter-
ference in his remarks during Commissioner Pai's panel.

  So, if the AM band ever does go all-digital, it would be
wise to consider all options before taking the leap.  Let's not
blindly trust iBiquity which has done such a poor job with AM
so far.

  P.S.  Another major AM station has shut off AM HD at
  night and there have been no listener complaints.  (Private
  communication to the CGC Communicator at the NAB Show.)

  P.S.2.  Riddle:  What happens when AM stations use FM
  translators?  It gives the public yet another reason not
  to listen to AM.

******************************************************************

  SERIOUS SOLAR AT ZZYZX

  On Interstate 15 between Barstow and Las Vegas is a very
curious exit labeled "Zzyzx Rd."  The made-up name Zzyzx was
given to the area in 1944 by Curtis Springer, claiming it to be
the last word in the English language and, we are told, the last
word in health care.  He also established the Zzyzx Mineral
Springs and Health Spa the same year and used AM radio
broadcasting to attract customers from far and wide.

  Today the health spa is long gone but you will find in its
place an equally curious establishment called the Desert Studies
Center operated by California State University.  Here, researchers
stay for various lengths of time in the middle of nowhere.
Trouble is, the Center is so far removed that there is no
commercial electric power to run the lights, the scientific
equipment and the all-important air conditioning.

  Until recently, Zzyzx relied on diesel and propane generators
to meet their energy needs (an earlier attempt at solar simply
didn't produce much power).  Today, the generators serve as
peaking power providers and emergency backup sources because Zzyzx
has a new medium-sized solar power array to carry most of the
load.

  The solar panels track the sun along a single axis, tilting
from east to west each day under computer control.  There are a
total of 280 individual solar panels each producing 235 watts of
electricity in maximum sunlight.  After accounting for nominal
losses, we are told that the panels provide 58 kW max at 408 VDC.
There is even a feature that will automatically move the panels
to a flat horizontal plane position in the event of heavy winds.

  In addition to the solar array, Zzyzx has a temperature-
controlled battery building for overnight energy storage (new
battery cost = $400k but these batteries were purchased from AT&T
in virtually unused condition for only $90k).  There are also
multiple power inverters both before and after the battery bank.
The new installation went online in September 2012 and Desert
Studies Center is about to determine how well it meets their
summertime needs.

  Following are photographs showing the drive shafts and gearing
to tilt the solar panels, the survo-motor to do the tilting, a
portion of the air conditioned battery building and an eye-
pleasing old truck that just happened to be parked nearby:

  Special thanks to Desert Studies Center site manager Rob
Fulton for an excellent tour of the new solar plant.

The April 2013 Boston Marathon from an Amateur Radio Perspective

(From Amateur Radio Newsline Report 1862, April 19, 2013)

RESCUE RADIO:  HAM RADIO RESPONDS TO BOSTON MARATHON TERRORIST ATTACK

Some 250 ham radio operators were providing communications for the Boston Marathon on Monday, April 15th, when a pair of bombs believed planted by a terrorist went off killing three onlookers and sending scores to local hospitals.  Some with very serious and life threatening injuries.  Amateur Radio Newsline’s Mark Abramowicz, NT3V, is here with what’s known about the attack and the role played by the hams on scene:

It is a day Paul Topolski, W1SEX, will never forget.

Topolski tells Newsline he was working with radio operators close to the finish line of the Boston Marathon and things were going well.  And then, there was the first blast.

“I was in the net control trailer about 400 feet from where the blast was,” he recalls. “Things were going pretty smooth and we had and were commenting all of the operations that we had were up and running and no real issues.

“And, within a couple of minutes, my assistant and I just happened to be looking at each other out of the corner of our eye and then that blast hit and shook the trailer and we knew it wasn’t good.”
Topolski says then the second blast went off and they knew things were going to be brought to a halt. He says their big concern, operators at the medical tents at each mile along the route…

“Net control immediately started doing a roll call and finding out where all our people were – exact locations and their conditions, making sure that they were okay.  And, as it turns out everyone was just fine and continuing operations.”

Just before that roll call began, Topolski told his counterpart overseeing net-control on the course to reach out to him on a secure line.

Steve Schwarm, W3EVE, who also spoke with Newsline about the events of that day, was on the receiving end of that call and was a bit surprised.

“He calls me on the radio and says, ‘Call me on my cell phone.’  And, I know something’s got to be wrong because he’ll only talk to me on the cell phone when it’s something he doesn’t want anybody else to hear,” Schwarm says.

“So, I called him on the cell phone and that’s when he told me that two bombs had gone off in downtown and said I don’t know what’s going to happen next, but thought you’d like to know and I said thanks.

“So, I stopped all the activity in my net control and announced it to everybody there and I said that we don’t know what’s going to happen next, but I’m quite sure the race is probably over.”
Topolski, who was at the medical tent close to the finish line, says once it was established all those close to the bomb locations were okay, there was general agreement among the operators to stay at their posts and assist…

“It was a kind of a mindset, ‘Okay, we did have a problem and let’s continue to do our jobs,’ and everybody did just that until we were finally sent on our way by the Boston Police Department and the Massachusetts State Police because we were literally right in the “ground zero” area,” Topolski says. “We were in the crime scene so we had to bug out.”

But, before they were sent out, Topolski says the operators were busy helping medical personnel…

“Instead of taking care of runners, we were no working with the medical people who were serving casualties from the incident itself,” Topolski says. “We had medical coverage, or coverage in the medical tents and we started receiving reports of those injuries and the types of things that were going on and then we were relaying that information to the public safety people via WebEOC and other means.”

Topolski estimates those closest to the blast zones were there for about 35 minutes afterward until they got sent out because of concerns among authorities about other possible devices.
Back to Schwarm at course net control, who in the minutes after the blasts was now working with operators still out on the course.

“Police were ordering people to stop,” Schwarm says. “So runners tended to congregate at the first aid stations and the water-fluid stations along the course. And all of them had ham radio operators.

“So, as soon as that happened, we told everybody on the frequency what was going on. The event had stopped and they would start to organize those people. And, then we started to use some of our medical sweep buses to take the runners to some pre-determined shelters.
“The original thought was that if we had something like a thunderstorm come through and had lightning and things like that we wouldn’t want all these people on the course. So, that was the original intended use for the shelters but they found out that they could be used for this as well.”
Schwarm says for the operators close to the blast zones, it was a hectic time….

“They supplied communications for the medical tents and that was where a lot of the initial triage of the runners occurred and a lot of lives were probably saved because they had basically a first-class emergency room right there,” Schwarm says.

But the day was far from over for Topolski and his operators who were evacuated from the developing crime scene, Schwarm says….

“The roles actually got reversed because they were concerned about having another device in the area so they had a lot of people evacuated,” Schwarm says. “Paul and his team evacuated and several of his operators came up to help me in case we were going to be doing an extended operation.

“It wasn’t clear how long it was going to take for us to get this thing cleaned up and they came up to help in case we needed some backup. I was very concerned about some of my net control operators getting exhausted, needing some backup. So I knew he had some good people and they came up to help out.”

So, where was net control for the course? Schwarm says the Boston area hams put it at a perfect location…

“We’re actually quite a distance from the course,” Schwarm says. “We’re about a mile or two from the course. It’s at a facility, it’s a private school in Brookline which is a suburb of Boston.

“And, it’s on top of a very high hill, which, if we had to, we could probably work every single repeater we use with a 100-milliwatt walkie-talkie because we can see them all – literally. And, it makes an ideal location for it and we also then have high-speed internet at our fingertips and several phone lines and a few things like that. It’s a very nice facility.”

So what form of communications do the hams who work the Boston Marathon use? VHF frequencies only, Schwarm says…

“The Boston Marathon is the only marathon that’s run in a straight line,” Schwarm explains. “And we plan on having HT-coverage for the entire course and the finish and the start. So, as a result, you tend to use a fair number of frequencies to make that happen.

“We use five separate repeaters to cover five sections of the course. And, then we have a network of linked repeaters that we use to cover the entire course from beginnning to end just for things that need to be covered across that range.”

Topolski has been involved in the marathon amateur radio coverage for 20 years. For Schwarm, this was his 13th year and he says it won’t be his last.

“I think what you’ll find is that next year we’re going to have a bigger and better Boston Marathon and we’re going to go on,” Schwarm says. “I mean we went through a lot of planning and soul searching for these kinds of things after 9-11 and this was probably a wake-up call to re-think some of those.”
