City looking at antenna ordinance change

OLIVE BRANCH - An Olive Branch man's recent installation of a 58-foot-tall amateur radio antenna outside 
his home has prompted officials to review the city's related ordinance and propose some changes.

Aldermen have set a March 16 public hearing to take comments about amending the ordinance to require proof, 
before permitting, any tower would not end up off its owner's property if it fell.

Olive Branch's current ordinance allows antennas shorter than 35 feet tall to be installed 
without a conditional use permit as required for taller ones.

But complaints from residents in the Eastover subdivision and aired during a Board of Aldermen 
meeting earlier this month called attention to the ordinance.

The complaints came as Eastover resident and amateur radio operator Ron Fox appealed to the board for a conditional use permit
 previously denied by the Board of Adjustment - for a 58-foot-tall antenna on his property.

Several of Fox's neighbors told aldermen they were upset about the antenna as it is an eyesore, was erected without a 
permit in October, poses a threat of falling on their homes and causes interference with some electronics.

After tabling Fox's appeal for two weeks, aldermen on Tuesday voted to deny his 
permit request and give him 30 days to take down the antenna.

In other action Tuesday, aldermen gave homebuilders until Jan. 1, 2011 to begin complying with one section 
of the 2006 IRC Building Code the city uses. Homebuilders asked for the reprieve two weeks earlier, saying the code's requirement of 
pre-engineered panels for earthquake protection was too costly.

Chris Massey, president of the Home Builders Association of North Mississippi, estimated the cost at $2,500 for a 1,800-square-feet 
home and said it was not feasible to add it onto a sales price in today's slow real estate market.

Mayor Sam Rikard said all other requirements of the 2006 code remain in effect.



What Cellular was to 2mtrs, Twitter is to Skywarn

DRIVERS, TWEETERS DEPUTIZED AS MOBILE METEOROLOGISTS

Think you have what it takes to be a meteorologist? If so, the National Weather Service wants you.


The National Weather Service (NWS) wants you, your car and your cell phone. Specifically, 

NWS wants weather data from all three of those sources.

A brand new program using Twitter to gather weather information has just been launched. 

At the same time, Meteorologists are testing out a system to turn cars into roving weather stations, 

so drivers everywhere will know exactly what the road ahead has in store.

The new projects are designed to fill in the vast spaces among the more than 120 NWS forecast offices 

nationwide and their many, but still limited, number of trained volunteer weather spotters.




MARS Gets New Name As It Fine Tunes Mission


On Wednesday, December 23, the Department of Defense (DoD) issued an Instruction concerning MARS, effective immediately. This Instruction gives the three MARS services -- Army, Air Force and Navy/Marine Corps -- a new focus on homeland security and a new name: Military Auxiliary Radio System. The Instruction is the first major revision to MARS since January 26, 1988 -- as such, the first revision since the 9/11 attacks and Hurricane Katrina, two major events that changed the way Amateur Radio dealt with emergency communications.


Lasers Speak to Subs

Communicating with subs under­wa­ter is beyond tough. Sound moves through sea­wa­ter in very strange ways, with water tem­per­a­ture, salin­ity, and den­sity speed­ing up and slow­ing things down — gar­bling con­ver­sa­tions in the process. Electromagnetic trans­mis­sions (like radio) are no bet­ter — the sea has some funky elec­tri­cal con­duc­tiv­ity. During the Cold War, sub author­ity Joe Buff notes, the Navy man­aged to get super-​​simple, one-​​way mes­sages to its subs, with a pair of giant (28-​​mile!) extremely low fre­quency trans­mit­ters, based in the Midwest. But those trans­mit­ters were shut down, a few years back.

DPPS_Beam_Fan.JPG
The Navy’s new idea is to get specially-​​tuned lasers to han­dle the job, instead. The ser­vice has handed out a pair of small busi­ness inno­va­tion research con­tracts to Bothell, WA’s Aculight Corporation and Bedford, MA-​​based Q-​​Peak to build blue-​​green, quick-​​burst lasers for trans­mit­ting mes­sages across the deep. Acluight, for exam­ple, wants to use a com­bi­na­tion of semi­con­duc­tor and fiber lasers to pro­duce a low power beam (around 10 watts) at about 532nm spec­trum range. The idea is to get pulses as quick as half a nanosec­ond, repeat­ing as much as 10 mil­lion times per sec­ond.
Blue-​​green lasers have been dis­cussed for a while as poten­tial sub-​​talkers, with good rea­son. Seawater has a lot of organic junk float­ing around inside, which makes it “tur­bid” — “nearly opaque to light over much of any dis­tance,” Buff explains.

Blue-​​green light’s fre­quency is best at pen­e­trat­ing through this tur­bid­ity, given the mix of sizes in microns of the par­ti­cles and other stuff that pre­vents sea­wa­ter from being trans­par­ent. (Of course, some areas such as the Bahamas are famous for the clar­ity of their water, but this is very much the excep­tion, not the rule, glob­ally speak­ing.) This same tur­bid­ity is essen­tial to giv­ing sub­marines their invis­i­bil­ity while sub­merged, so it’s a dou­ble edged sword.


New Ears Coming for Joes

The Joint Program Executive Office Joint Tactical Radio Systems (JPEO-​​JTRS) is devel­op­ing the Rifleman Radio as part of an effort to bring secure, net­work­ing capa­bil­i­ties to the intra-​​squad level.

The Rifleman Radio is inter­op­er­a­ble, soft­ware pro­gram­ma­ble and upgrad­able and employs the Soldier Radio Waveform. It is ruggedi­zed and light, includes a con­ve­nient push-​​to-​​talk, and a hands-​​free head­set. The sys­tem is self-​​networking and will expand and con­tract as radios are added or sub­tracted from the net. Recently tests of the new radio were con­ducted at Fort Bliss, Texas with the 1st Armored Division.

Right now, the indi­vid­ual Soldiers and their squad lead­ers are the biggest have-​​nots within the com­mu­ni­ca­tions arena, said Maj. Tracy Mann, of the TRADOC Capability Manager for Tactical Radios. This capa­bil­ity will allow squad lead­ers and team lead­ers to talk directly to their sub­or­di­nates, and their sub­or­di­nate lead­ers to be able to com­mand and con­trol their indi­vid­ual squad and pla­toon bat­tle troops.

By employ­ing a National Security Agency Type 2 cer­ti­fi­ca­tion, the Rifleman Radio can offer con­trolled but unclas­si­fied com­mu­ni­ca­tions a Soldier can employ with­out requir­ing secu­rity clear­ances. This solves one radio prob­lem for infantry units, which are com­prised mostly of troops who are not cleared. The NSA Type 2 encryp­tion bars clas­si­fied infor­ma­tion from being passed dur­ing trans­mis­sions and makes secure infor­ma­tion more dif­fi­cult for ene­mies to inter­cept. With these fac­tors in place, the Rifleman Radio will not only deliver 10 to 100 times the band­width to the tac­ti­cal edge, but at the same time, make shar­ing infor­ma­tion more secure for the Soldier.

In addi­tion to voice com­mu­ni­ca­tion, the Rifleman radio also sup­plies a com­man­der with a GPS pic­ture of his squad mem­bers through a Position Location Information, or PLI, dis­play. At Fort Bliss, the 1st Armored Division used the GPS fea­tures of the Rifleman Radio in a shoot-​​house sit­u­a­tion. Squad lead­ers posi­tioned out­side of a dark­ened room were able to locate and iden­tify the posi­tions of each mem­ber of their team through the PLI.

The Rifleman Radio is being devel­oped as a stand alone sys­tem, but will inte­grate into the Ground Soldier System Ensemble plat­form pro­vid­ing mis­sion plan­ning, exe­cu­tion, and sit­u­a­tional aware­ness capa­bil­i­ties to squad team lead­ers and above. The Rifleman Radio will also be inter­op­er­a­ble with the other suite of JTRS prod­ucts being devel­oped includ­ing the Ground Mobile Radio and HMS Manpack radio, to pro­vide the needed con­nec­tiv­ity to higher ech­e­lon com­mand elements.


ICOM IC-706MKIIG the final word!

Submitted by Arvadmin on Tue, 08/12/2009 - 19:58

Despite deniers in the USA, it has been confirmed that Wednesday 9 December is the last day that the ICOM plant in Wakayama Japan will produce the IC-706 MKIIG transceiver.

ICOM Australia said it has checked with Japan and been reassured that the earlier advice received that the popular transceiver has been discontinued is correct.

The reason is that some components used in the IC-706MKIIG are no longer available and the model had to cease production.

ICOM Australia’s authorized agents were told in writing last month that only back orders received before 30 November would be supplied before production stopped. Also now out of 

production are the IC-T90A, IC-2720H, IC-910H and a few receivers.

The only source of denials is the USA, which includes ICOM America stating that the transceiver will remain on its product line. That could simply be due to it holding sufficient stock.

Perhaps there may be model run-out pricing for the discontinued transceiver in the new year?

In Australia the biggest seller of amateur radio equipment and ICOM agent, Strictly Ham said it has a back order and with stock on hand fewer than 20 were left to sell.

News from Australia via authorised ICOM agents that the production of the IC-706MKIIg transceiver is ending has attracted counter claims by ICOM America.

Clearly the news is unpalatable. However after four days of inquiry, and in the absence deniers in Europe, Asia or elsewhere, the only conclusion is that arguably the most popular rig in 

modern times has stopped being made.

The compact mobile transceiver that is equally at its best when used as a base station and widely featured in numerous DXpeditions, first appeared just as the IC-706 in 1995.

That first model was HF, 6m and 10w on 2m. Then followed the IC-706MKII in

1997 with the 2m power output lifted to 20w.

In 1999 the MKIIG arrived with 50w on 2m plus 70cm with 20w, making it a very sought after transceiver. It’s long-life is testament to its utility.

We have a new amateur repeater up in Collierville.  The frequency is receive 444.125 and transmit is 449.125 (pl 107.2).  

The repeater was put up on the Town of Collierville Public Safety tower behind the Animal Shelter on South Street.  

The repeater was loaned to us by Andy Masters (NU50) and the Town of Collierville is letting us utilize a spare antenna that is located on the tower at 360 feet.  

The spare antenna is only utilized in the event the public safety system has an antenna problem and we will need to take the ham repeater off line.  

We are looking to acquire some funding to put up an antenna just for the ham operation.  Also the current antenna is an omni antenna, 

but the pattern is aimed toward the center of Shelby County, so if you get on the back side of the tower, the range will probably decrease.

 Also, some of you may know, Gary Ruble is leaving us for East Tennessee, why he would leave the greater metropolitan area of Memphis for East Tennessee, 

I will not understand.  But with that said, I need a new leader to step up.  If anyone wishes to help in this area, I would greatly appreciate it, so just let me know.

HAMS BEING ATTACKED

 

submitted by Crazy Cary WA4EWG

"The Cave Man of Walls, MS"


Ham Radio Operators a danger to our children...

What characteristic is shared by an electric blanket, a power line, and a
broadcast tower? All three emit electromagnetic radiation.

These invisible electromagnetic fields are known as EMFs. They are generated
by currents running through electric wires. Since they are not
powerful and destructive like nuclear or X-ray radiation, they were once
thought to be harmless. However, studies have suggested that people
exposed to them chronically run a higher risk of certain health problems,
including miscarriages, learning disabilities, and cancer.

Did you know that Ham Radio Operators run 1500 watts of power in your
neighborhood exposing your family to dangerous radiation?

Is there a ham radio operator in your neighborhood? You can find out easily
by a large antenna in your neighbor yards and doing a search for
hams by zip code at
http://www.qrz.com/db/    The reason you need to search
for hams in your neighborhood is because they can run their 1500 watt
transmitters with a small wire dipole and vertical antennas hidden in trees
and flag poles. Unlike CB radio operators who are limited to a very low 4
watt transmitters in your
neighborhood hams can do more damage to your children with there 1500 watt
transmitters. How much power does your local AM radio station run? On
average they only run 1000 watts, but the transmitting antennas are usually
in remote unpopulated areas. Ham radio operators run there high powered
transmitters right in your neighborhood.

How to put a stop to ham radio operators from polluting your neighborhood:
1. Write your congressman about protecting your children from harmful EMF.
2. Demand that the FCC certify every ham radio operator in your area comply
with RF exposure regulations by writing the FCC.
http://www.fcc.gov/eb/AmaCmpl.html
3. Contact your local city council and mayor to lobby to change Federal law
regarding using high powered transmitters in your
neighborhood.
4. If you live in a neighborhood with a covenant then contact the HOA and
demand that it be changed to exclude licensed ham radio operators from
living in the neighborhood, it is not enough to ban large antennas since the
ham radio operator will put up a small wire antenna or an antenna in
their attic to transmit up to 1500 watts of power.
5. If you find out a ham is in your neighborhood let your neighbors know so
they can contact your city council and congress representative to
change the law to mandate a lower power usage of ham radio around your
family.
6. Ham radio operators lower your property values with there large antennas
and the increasing knowledge that high power transmitters effect
every family in the neighborhood with harmful EMF radiation.
