ARRL: No Need to Relocate Ham Band for Vehicular Radar



The ARRL has told the FCC there is no need to modify the current amateur radio allocation at 77-81 GHz in order to accommodate expanded spectrum space for vehicular radar, and notes that neither the original petitioner nor any of the commenters have made such a request. In comments on an FCC proposal to expand the vehicular radar allocation from its current 76-77 GHz to include 78-81 GHz, the ARRL says it has worked closely with petitioner Robert Bosch, LLC, and that both groups are satisfied that vehicular radar and amateur radio can "play nicely together" on the band, according to an ARRL bulletin.
 
Acknowledging the possibility that the Commission may choose to reallocate the 4-millimeter ham band despite its protests, the ARRL requested the assignment of "equivalent spectrum" at 75.5-76 GHz and 81-81.5 GHz. The current amateur allocation at 4 mm is 77-81 GHz, with primary status in the 77.5-78-GHz segment.

WWV Keeps On Keepin' On at 25 MHz

An "experimental" reactivation of WWV's time and standard frequency transmissions on 25 MHz is continuing after a year, according to the ARRL Letter, with no plans as of now to discontinue the broadcasts. WWV had shut down its 25-MHz transmitter in 1977 but reactivated it a year ago in response to an e-mail lamenting its loss from Dean Lewis, W9WGV. The 1-kW signal provides not only exact time and frequency, but helps serve as an indication of propagation conditions on 12 and 10 meters. WWV welcomes signal reports and listener comments.

Updates, Growth for Broadband Hamnet


One of the ways in which ham radio can help fill in gaps in internet service when normal infrastructure is knocked out is via ad-hoc self-organizing RF computer networks, now referred to as Broadband Hamnet. Flying mostly under the radar so far, the technology now seems poised for a significant boost in usability, according to several reports on both Newsline and the ARRL Letter.
 
In March, the developers of Broadband Hamnet announced a firmware upgrade for users of both Linksys WRT54G and Ubiquiti wireless routers, and a group calling itself the AREDN Project introduced new software for what it calls the Amateur Radio Emergency Data Network, or AREDN. According to Newsline, AREDN is being described as a new way by which hams providing emergency communications can support needs for high-speed data transmission. The AREDN software works with the mesh networks created using Broadband Hamnet and allows the interconnection of laptops, cell phones and other wireless devices. The networks may (or may not) also connect to the Internet. More information on AREDN is available from <www.aredn.org>.

Meanwhile, the ARRL Letter reports that a group of hams in Utah successfully deployed a Broadband Hamnet mesh network in support of a Boy Scouts "Scouting for Food" project in March. The group set up a network of 13 nodes across the Salt Lake Valley, linking back to the local scout headquarters and transmitting live video and audio from each of the food drop-off points and the truck dispatch location. Described by one of the participants as "Wi-Fi on steroids," the 2.4-GHz network covered distances of more than eight miles from the central hub site.

Space Station Scatter?


Can the International Space Station be used to bounce
signals for intercontinental contacts on 2 meters? A ham
in Namibia and another in Brazil are planning to find out!

Two hams on two continents are planning to try to make contact on 2 meters by bouncing signals off the International Space Station as it passes over the South Atlantic Ocean.

 The South African Radio League reports that Namibian ham Pieter Jacobs, V51PJ, and Brazilian amateur Marcos Turbo, PY1MHZ, are planning to conduct scatter tests from the ISS on 144 MHz. 

The overall path length has been calculated as 5000 kilometers (approximately 3100 miles), with each station's signal needing to travel 2500 km (1550 miles) before bouncing off the space station. We'll do our best to keep you posted on their progress.

FCC Proposes Broadband CB Service


The Citizens Broadband Radio Service is the name bestowed by the FCC on a proposed new broadband wireless service that would be open to all, with very few restrictions on the types of applications permitted in the band. According to eweek.com, the FCC proposed the new service in a March 27 Notice of Proposed Rulemaking (NPRM) and planned to put it to a vote on April 17. The new service would initially operate between 3.550 and 3.650 GHz, with room for possible expansion to 3.700 GHz. Individual licensing would not be required and incumbent users would be protected from harmful interference.
 
According to eweek, the concept behind the new service is "to support activities including small cell deployments, fixed wireless broadband services and something the FCC calls general consumer use."  Apparently, the flexible structure of the plan is designed to promote experimentation by individuals as well as use by small and large wireless service providers.

The proposed new band begins just 50 MHz above the top end of the 9-centimeter ham band, so it's possible that a new market for consumer-grade equipment designed to operate at 3550 MHz could also help make more affordable equipment available for amateur use at 3300-3500 MHz. (Tnx K8RKD)

New Privileges for Hams in South Africa and UK


New rules published by South Africa's telecommunications regulators now allow amateurs there to use up to 1000 watts of output power on most bands (with Class B licensees getting a boost to 100 watts), along with an expansion of the 160-meter band all the way to 2 MHz. This, according to the South African Radio League.
 
A few thousand miles to the north, full-license hams in parts of the United Kingdom and its "Crown Dependencies" will soon be gaining data privileges on the 4-meter band, from 70.5 to 71.5 MHz. This band has long been available to amateurs in many European countries, but not those in the Americas, where 70 MHz was used for commercial television broadcasting. According to Newsline, hams in most of the UK (excluding Scotland) will be able to apply for "Notices of Variation" to permit operation on 4 meters. The allocation is not permanent and is subject to reassignment on 12 months' notice.

One of the fathers of slow-scan television has become a Silent Key. Don Miller, W9NTP, died on March 22 at age 91. According to the ARRL Letter, Miller worked closely with Cop MacDonald, VY2CM, in developing SSTV. Miller also founded Wyman Research, Inc., which built SSTV/ATV equipment for hams, including the SSTV station used aboard the Russian Mir space station. Miller wrote about SSTV on Mir in CQ VHF back in the 1990s.

U.S. Ham Licensing Numbers at All-Time High


The ARRL-VEC reports that the ham radio population in the United States hit an all-time high of 726,725 as of the end of 2014, and has continued growing to more than 727,000 in the first two months of 2015. According to the ARRL Letter, ARRL-VEC Manager Maria Somma, AB1FM, said the number of licensed amateurs in the United States has grown by more than 8 percent in the past decade. In addition, she said, there were 33,000 new licensees in 2014, an increase of 15% over 2013. Plus, Somma added, the ARRL-VEC conducted a record 7216 license exam sessions last year, crossing the 7000 threshold for the first time.

prime sponsor of HR 1301, which
would extend FCC limit on amateur
antenna installations to include
private land use agreements.
(U.S. Congress photo)
A bill to require the FCC to extend the “reasonable accommodation” requirements of its rules regarding amateur radio antennas and support structures to private land use contracts has been re-introduced in the U.S. House of Representatives. H.R. 1301, the Amateur Radio Parity Act of 2015, is identical to a previous bill that died at the end of the last Congressional session.

Introduced by Rep. Adam Kinzinger (R-IL) with bi-partisan support from a dozen co-sponsors, the bill would include homeowner association rules and deed restrictions (commonly known as CC&Rs) under the protections currently granted to amateurs from overly-restrictive state and local zoning laws and ordinances. Those protections include requirements that any restrictions on amateur antennas and support structures must “reasonably accommodate” amateur operation and must represent the “minimum practicable” restrictions to accomplish the regulatory authority’s legitimate purposes.

The ARRL encourages all amateurs to urge their representatives in Congress to support and/or co-sponsor the new bill.

“Totally Remote” Multi-Op Contesting


A team of contesters believes it may have broken new ground with a remote multi-op effort in February’s ARRL DX Contest CW weekend. A half-dozen different hams operated contest station K4VV in northern Virginia (using the call sign K3TN) from several different locations scattered from Maryland to Florida. According to the ARRL Letter, members of the group each activated the contest station from their homes in Virginia and North Carolina, while one started the competition from his home in Maryland and finished the weekend at his condo in Florida. It was pointed out that, due to a snowstorm, the K4VV station was inaccessible during the contest weekend.

ARRL Seeks Input on HF Band Plan Changes


The ARRL is looking for member comments on a variety of proposals aimed at limiting the frequencies on which wideband digital modes are permitted and expanding the HF operating privileges available to Novices and Technicians. Some of the proposed changes would affect only the voluntary band plans that informally structure the HF amateur allocations. Others – such as expanding the CW/data/RTTY subband on 80 meters or granting RTTY/data privileges to Techs and Novices on 80 and 15 meters – would involve petitioning the FCC for rule changes. Details of the proposed changes and a form for submitting comments may be found on the ARRL website at < www.arrl.org >. Member comments are due by April 19.

Proposal to Cut FCC Enforcement Resources


The ARRL reports that it has obtained an internal FCC memo in which the Enforcement Bureau lays out plans to ask the full Commission to close two-thirds of its field offices and to cut in half the current number of field agents. In their place, the bureau is proposing the formation of flexible “Tiger Team” strike forces that could be deployed as needed to deal with enforcement issues.

ARRL CEO Dave Sumner, K1ZZ, was troubled by the plan, noting that enforcement already appears to be a low priority at the FCC and that reducing its “geographic footprint and number of field agents” is the wrong path to follow.

RadioShack Makes Deal to Sell More Than Half its Stores


Working under the reorganization rules of Chapter 11 of the federal bankruptcy laws, RadioShack reportedly has reached an agreement with General Wireless, Inc. to purchase as many as 2400 its 4000+ company-owned stores. Many others will be closed. 

According to the ARRL Letter, General Wireless – which is affiliated with RadioShack creditor Standard General – has reached an agreement in principle with to open “store within a store” Sprint wireless retail locations in up to 1750 of its newly acquired RadioShack stores.

There is no indication of whether these stores would continue to operate under the RadioShack name or if they would continue to sell electronic components and other products favored by hobbyists.

ARRL to MITRE: Don’t Mess With HF Ham Bands



MITRE Corporation headquarters
(from mitre.org)
The MITRE Corporation has an FCC experimental license to test wideband communication techniques on a variety of HF frequencies between 2.5 and 16 MHz. 

The ARRL Letter reports that ARRL Chief Counsel Chris Imlay, W3KD, has sent the company a letter asking that it either structure its tests to avoid HF amateur bands or, at minimum, to provide advance notice of times and frequencies of planned transmissions. 

The ARRL’s concern, according to the Letter, is that “with the operating parameters proposed, it will be impossible to conduct your tests … within the Amateur Radio allocations and … avoid harmful interference.” A further concern is that due to the nature of the transmissions, “amateur licensees will have no way to determine the source of the interference or know to whom they might complain.” At press time, there had been no response from MITRE.

German Hams Become Shortwave Broadcasters


(From www.channel292.de)
A group of hams in Germany has received a license to operate a shortwave broadcast station on the 49-meter band frequency abandoned two years ago by that country’s premier international broadcaster, Deutsche Welle. “Channel 292” is now broadcasting around ten hours a day, generally from about 0700-1700 UTC, on 6070 kHz, using a 10-kilowatt transmitter built partially from parts of the old 500-kW Deutsche Welle transmitter and a dipole antenna. The station’s signal covers much of western Europe, but has also been heard in Russia and North America, according to the ARRL Letter.


Privately owned by a group of German hams, the station has a business relationship with Germany’s national ham radio organization, the Deutscher Amateur Radio Club, and is also known as DARC Radio. The DARC produces a weekly ham-oriented magazine show in German. The ARRL Letter reports that the Radio Society of Great Britain has expressed interest in contributing English-language segments.

Other programming on the station is leased, with programs airing in a variety of languages. Reception reports will be QSLed via the DARC outgoing QSL bureau. For more information, visit http://www.channel292.de.

Space and Satellite Roundup

Imagine having your “sked” delayed by a spacewalk! That’s exactly what happened to a school group in Florida that was scheduled to have an Amateur Radio on the International Space Station (ARISS) contact on February 25. A series of spacewalks in late February to prepare the station to dock with commercial U.S. rockets also resulted in a cutback of planned slow-scan TV transmissions from the station. According to the ARRL Letter, all ham transmissions are suspended for during spacewalks for crew safety.

Speaking of ARISS, the program is now accepting applications for school contacts in the first half of 2016, with a focus on educational organizations with the potential to draw large numbers of participants and integrate the contact into a well-developed educational plan. The application deadline is April 15.

AMSAT-NA’s Fox-1A satellite is ready for launch, having passed its Mission Readiness Review in late February. Integration with the launch vehicle was scheduled for March 25, with
a tentative launch from California in late August of this year.

The European Space Agency is offering a ride to deep space for as many as six small cubesats and is hosting a competition to select those projects that will be accepted. The AMSAT News Service says the small satellites will be launched in 2020 along with Asteroid Impact Mission. The judges are looking for projects that will “produce meaningful scientific return” from deep space.

Finally, NASA is making available a collection of soundbites from space that are suitable for use as ringtones. Among the available files, according to the ARRL Letter, is one of the Juno spacecraft sending “HI” in Morse code during a flyby of Earth in 2013.

NCDXF Grants $50k to DXpedition Group



The Intrepid-DX Group is the recipient of a $50,000 donation from the Northern California DX Foundation (NCDXF), in support of its planned DXpedition early next year to South Sandwich Island (VP8S) and South Georgia Island (VP8G) .

The group anticipates that the 10-day visit to the two islands in the southern Atlantic Ocean will cost more than $400,000. They are British overseas territories and very high on most DXers’ most-wanted lists.

U.S. to Propose More Sharing of 10 GHz at WRC-15


The U.S. government is working on its proposals and positions for this year’s World Radiocommunication Conference (WRC-15). Among them is a proposal to add 600 MHz to the spectrum currently available to the Earth Exploration Satellite Service (EESS) in the vicinity of 10 GHz, also known as “X-band.” Amateur radio currently has a secondary allocation from 10.0-10.5 GHz, with a specified segment for the Amateur Satellite Service between 10.45 and 10.5 GHz. The ARRL Letter says the proposal would consider amateur satellites already in service at the time of the change to have co-equal status with the scientific satellites, but that any launched after that time would have secondary status. The ARRL has been involved in the discussions and is monitoring them closely.
