100 Years of Amateur Radio
Irving Vermilya, 1HAA, later W1ZE, became the first licensed amateur in the USA being issued Certificate of Skill #1 and is known for all time as Amateur Number One. A number of other amateurs followed suit and rather than seeing amateur radio die out as the Law's authors obviously intended, amateur radio began to flourish with a combination of adopting new technology (Edwin H. Armstrong invented the regenerative receiver in September 1912) for reception and later transmitting (CW emissions became feasible after the World War) along with organizing message relay routes. Amateurs led the way finding that the wavelengths shorter than 200 meters were not useless through the new technologies and, by the early 1920s, a declining solar cycle that enabled communications not only for transcontinental paths, but intercontinental as well.
A century later we enjoy this hobby of amateur radio precisely due to the unintended consequence of a law designed to kill amateur radio that did not state its intention exactly and instead allowed it to live and thrive for 15 years! In 1927 more comprehensive radio legislation was enacted and in 1934 the Communications Act created the FCC that we know today.
For more information visit the United States Early Radio History site by Thomas H. White. Thomas' site is not limited to amateur radio, however, and is quite comprehensive on a lot of radio topics. The ARRL publication, 200 Meters and Down by Clinton B. Desoto documents much of the early amateur radio history. An article by David Newkirk, ex WJ1Z, now W9VES, The Coming of The Law (available to ARRL members), published in the November 1993 issue of QST also documents the forces behind the enactment of the Radio Law of 1912 and how radio amateurs responded to it. The December 2012 issue of CQ has The Radio Act of 1912: A Century of Radio Regulation and Licensing by Rich Moseson, W2VU, providing another perspective on this red letter day. Certainly, more articles on this topic have been published over the years and make for good reading.
As of December 13, 2012 amateur radio will officially be 100 years old complete with examinations and licenses. Happy anniversary!

Superstorm Sandy: How You Can Help
Volunteers in New Jersey are being coordinated through an emergency response hotline, 1-800-JERSEY-7 (1-800-537-7397). Alternate numbers, for when the hotline isn’t staffed, include 609-775-5236 and 908-303-0471 or emails can be sent to Rowena.Madden@sos.state.nj.us.
The New York City agency NYC Service is coordinating volunteers for various relief projects in New York City. Go to its Facebook page or email nycservice@cityhall.nyc.gov with your name and email address.
The American Red Cross is collecting funds and coordinating blood donations. The organization sheltered more than 3,000 people across nine states during the worst of the storm. You can donate $10 by phone by texting the word REDCROSS to 90999.
Sandy has caused the cancellation of about 300 American Red Cross blood drives.
“Patients will still need blood despite the weather,” said Dr. Richard Benjamin, chief medical officer of the Red Cross, in a statement.
To schedule a blood donation at a center near you or for more information about giving blood or platelets, visit redcrossblood.org or call 1-800-RED CROSS (1-800-733-2767).
The American Society for the Prevention of Cruelty to Animals (ASPCA) takes donations to rescue and shelter animals affected by the storm. Nearly 300 animals are staying with their owners in shelters in the New York City area, the agency said.
The ASPCA is also setting up a distribution center in Syracuse, New York with 4,000 sheltering units, which contain pet food, crates, food bowls, toys, and anything else an animal may need.
The Salvation Army: You can donate $10 to the Salvation Army by texting “STORM” to 80888. If you are already volunteer-certified, you can sign up to help out with disaster relief.
AmeriCares: You can donate to AmeriCares’ relief fund to help the organization, which is distributing supplies to 130 clinics in the 13 states affected by Sandy.

Survival Preparedness
Who would have thought that some of the most populated areas in the U.S. would be going 5 days + without electricity, water, food & other necessities.
Many of you have laughed at me for storing food and survival gear, even some of my East Coast friends.
I not laughing at them and I do feel bad for them. It saddens me to see so many in dire straits (state of extreme distress.)
I pray several times a day for all those effected in this disaster.
It’s never too late to plan for a disaster.
Hurricane Sandy developed from a tropical wave in the western Caribbean Sea on October 22.
officials advised residents to prepare and or evacuate as early as October 24, 2012.
Here we are, it's November 2, 2012 and all hell is starting to break loose on the East Coast.

Ultimate QRSS Transmitter Kit
Note for WSPR users: the 30m kit has a 10.140MHz crystal which is suitable for either the QRSS sub-band or the WSPR frequency. Therefore on 30m the kit can be used as a standalone WSPR transmitter. On other bands you may need to supply a suitable crystal for the WSPR frequency on that band. Alternatively you could use this kit in the AF output mode, fed into a conventional SSB transmitter set to the frequency of your choice.
The kit supports the following modes:
- QRSS mode (plain on/off keyed slow CW)
- FSK/CW mode (frequency shift keyed slow CW)
- DFCW mode (dual frequency CW)
- WSPR mode (Weak Signal Propagation Reporter)
- Slow-Hellschreiber (frequency shifted slow-Hell)
- Full-speed Hellshreiber
- Half-speed (“DX”) Hellshreiber
- CW (plain CW)
- Customisable FSK patterns
- 24-character LCD + two-button user interface
- User-programmable (callsign, message, speed, FSK, mode, etc.), settings stored in EEPROM
- GPS interface, for locking the frequency in slow-speed modes
- On-chip generation of WSPR encoded message (no PC required)
- WSPR maidenhead locator can be generated from GPS-derived latitude/longitude
- Selectable “frame” size, for stacked QRSS reception
- Plain CW callsign identifier at selectable interval
- Produces 150mW RF output, or AF output for driving an SSB transceiver
- Higher output power by additional PA transistor and/or higher PA supply voltage

Sky Sat Communications of Montenegro & InnovAntennas
Sky Sat Communications of Montenegro appoints InnovAntennas Exclusive Distributor for its Advanced Contest Solutions Product Line in the North American and United Kingdom Markets
Sky Sat Communications, founded by internationally renown amateur radio contester Ranko Boca, 4O3A, today announced the appointment of InnovAntennas as exclusive distributor of its Advanced Contest Solutions line of ultra high performance Filters, Switches and Automation & Control Devices that ‘no serious shack should be without’ for the North American and United Kingdom markets with immediate effect.
The Sky Sat 4O3A product line is the result of many years of contest winning experience and development. The pitfalls of under performing mainstream products have been overcome to provide high-performing products giving serious contesters––and DXers––trouble-free functionality to ensure the points––and new DXCCs––keep racking up! In two short years Sky Sat’s customer base has expanded to include many of the world’s leading contesters and contest stations including 4O3A, OH8X, ES5TV, PY5EG, S51A, WX3B, YT3M, DR1A, LZ9W, LX8I, K3WW, UA3AB, S52X, CR2X, II9P, et al.
Sky Sat’s CEO Ranko Boca, 4O3A said “I have been looking for the right partners to expand Sky Sat’s reach into North America and the United Kingdom for some time and was delighted to discover that InnovAntennas, with operations on both sides of the Atlantic, could cover both markets. InnovAntennas fully understand the needs of contesters and DXers, the amateur radio world’s most demanding customers, and are well suited to provide sales and support for our products.”
InnovAntennas is now stocking and supporting the Sky Sat 4O3A filter products and will be making available the balance of the product line during the second half of 2012. Available immediately are the High Power 5-pole and 3-pole Monoband Band Pass Filters (Series S & Series L) for the HF contest bands: 80m, 40m, 20m, 15m and 10m, and the High Power HF Triplexer/Combiner. Stations using Tribander antennas to cover 20m, 15m and 10m can use the High Power HF Triplexer/Combiner in combination with Series S filters to operate simultaneously with a high level of isolation on all three bands with multiple transceivers sharing the same antenna – perfect for serious contest efforts from home, Field Day and DXpeditions. All 4O3A filters, including the Triplexer/Combiner, are rated for full legal power at high duty cycle modes such as RTTY.
InnovAntennas America co-founder & executive chairman William Hein said “InnovAntennas strives to sell only the absolute best, no compromise antennas and accessories and have found a kindred spirit in Ranko, 4O3A. My new personal contest station in Colorado is being designed around 4O3A-designed products in the shack and of course our own InnovAntennas products in the air. We look forward to a long, productive relationship with Sky Sat and can’t wait to see what comes next out of Ranko’s lab!”
About Sky Sat Communications
Ranko Boca, 4O3A, founded Sky Sat Communications, a producer of digital and analog transmitters for commercial TV and FM broadcasters as well as custom telecom products for a global market, in 1990.
Unsatisfied with the performance and quality of performance products made for hams, Boca and Sky Sat launched a Ham Radio Department in 2010. Boca (ex-YU6AD, YT6AA, YT6A) married his decades of hands on contest experience with the latest technology to create unique, ultra-high performance products designed and manufactured without comprise for the amateur radio world’s most demanding users: contesters and DXers.
About InnovAntennas
Justin Johnson, G0KSC, launched InnovAntennas, Ltd. in 2011 after his antenna designing hobby led to a flood of requests to “please make one for me” from amateur radio operators who recognized that Johnson’s designs outperformed anything they could buy from a store. InnovAntennas America, Inc. was launched in January 2012 by William Hein, AA7XT and is based in Glade Park, Colorado. The company’s antennas and accessories are available directly via InnovAntennas.us (for North America), InnovAntennas.com (for the rest of the world) and via a worldwide dealer network.

73
"The best number is 73. Why? 73 is the 21st prime number. Its mirror (37) is the 12th and its mirror (21) is the product of multiplying, 7 and 3. In binary, 73 is a palindrome, 1001001 which backwards is 1001001." Amateur Radio Operators often use the number 73 as an abbreviation for "best regards", typically when ending a QSO (a conversation with another Amateur Radio Operator).

Digifest 2012
The Annual Digifest will be held as usual on the 1st full weekend of June (2012 dates are June 2nd and 3rd ).
This is going to be Digifest’s 5th year and its popularity is growing with last year’s received LOGs number of more than 200.
Peculiarity of this Contest is the great variety of different categories of the participants in 5 digital modes: RTTY 75, BPSK 63, MFSK 16, HELLSCHREIBER, OLIVIA
and the most fair points calculation based on the distance between the stations.
The Contest consists of 3 convenient periods (8 hours each) during the weekend.
To add more adrenalin into this competition a special feature will be offered to those who like competing in real time – online results will be presented on a server.
And, of course, a lot of real nice prizes, mostly RigExpert AA-230 and AA-30 Antenna Analyzers and RigExpert USB Interfaces. All prizes sponsored by RigExpert Ukraine Ltd.
Since the number of the participants is relatively small and the most populated competing area is Europe, the “far away” stations from NA, SA, Africa, Asia and Australia are at great advantage.
From the last years’ experience those stations were the most prize winners. Considering this and also to support growing participation from Europe,
the sponsors “double” the prizes – i.e. separate main prizes are now available both for Europe and for the “rest of the World”.
But wait, that’s not all! For those of you who won’t be able to win “main prize” in respected category, there will be a lot of small gifts, like T-shirts and paper awards.
All the prizes will be mailed to participants’ home addresses.
The results are usually available just 2 weeks after the end of the Contest,
So, lets just meet on the 1st weekend of June and have fun!

Internet Doomsday; July 9, 2012
Unknown to most of them, their problem began when international hackers ran an online advertising scam to take control of infected computers around the world. In a highly unusual response, the FBI set up a safety net months ago using government computers to prevent Internet disruptions for those infected users. But that system will be shut down July 9 -- killing connections for those people.
The FBI has run an impressive campaign for months, encouraging people to visit a website that will inform them whether they're infected and explain how to fix the problem. After July 9, infected users won't be able to connect to the Internet.

Yaesu FT1D digital FM handheld.
One of the most eagerly awaited products at Dayton Hamvention was the new Yaesu FT1D digital FM handheld.
It has, for an Amateur Radio rig, a number of innovations:
- A microphone that uses a mini-USB plug and has a built-in camera for low resolution (320x240) pictures,
- An 80 character group short messaging facility
- 9600 bps data transfer
- Micro-SD card slot
- E-GPS facility
Although the optonal extra microphone has a camera there appears to be no way to display the pictures on the radio which some may see as reducing it's usefulness.
The use of 9600 bps with 12.5 kHz channel spacing (is it 10 kHz in Japan?) was a surprise. Some had expected it to support 5 or 6.25 kHz channel spacing with a resultant data rate of 4800 bps (digital speech using an AMBE vocoder only requires a 3600 bps data rate).
The modulation used is what Yaesu describes as C4FM otherwise known as 4 level FSK or 4-FSK and is the same as that used for Digital PMR-446 equipment. 4-FSK has advantages over other types of digital modulation such as GMSK.
Both ICOM and Kenwood have been producing 4-FSK equipment for the PMR market since 2007 so in some ways it's surprising that Yaesu beat them both in releasing an amateur version of 4-FSK.
As yet Yaesu hasn't announced any mobiles, base stations or repeaters so it appears that FT1D's can only talk to other FT1D's in digital mode.
After Dayton some questions remain:
- Does it have APRS? The website of at least one amateur radio dealer had been saying the rig did APRS but the brochure makes no mention of it only refering to E-GPS
- Which Vocoder does it use? The AMBE seems the obvious choice but the brochure doesn't say
- What will it cost? Yaesu currently sell the VXD-10 high power digital handheld to the leisure market for 63,000 yen ($796) hopefully the FT1D will be cheaper!
http://tinyurl.com/VXD10-Handheld
- When will the FT1D be available? Well one Japanese retailer indicates that it could be another six months, see
http://tinyurl.com/CQCQDE-Shop

to find them. There is no competition with this hunt, just the fun of
finding these little boxes.
Bring your own equipment, or there will be gear there to be loaned out
for you to hunt within the park.

Vanity Callsign Fee to Increase .80 ¢
The FCC has released a Notice of Proposed Rule making that, among other things, would raise the cost of obtaining a vanity callsign to $15.00 for a ten year license term. The current cost is $14.20 which in essence means an increase of only 80 ¢ if the rule making is approved. (FCC)

BSA Announce "Interpreter Strip" for Morse Code
The Boy Scouts of America have just announced a new
"Interpreter Strip" for Morse Code. An "Interpreter Strip"
on the uniform means that the Scout or adult leader is able
to communicate in a particular language.
--
Those older Scouts and former Scouts among you may remember
the Boy Scout requirements that said a Scout had to learn
Morse Code or signal flags to send and receive a message.
And, even though that requirement has disappeared and Morse
Code is no longer mandatory to get any amateur radio license
in the United States, the BSA is reviving Morse Code as a
"language" worth learning.
You can probably credit Jim Wilson, K5ND, for getting this
one from concept to reality.
He's the BSA's "Jamboree on the Air" organizer and the
volunteer chairman for the next K2BSA operation at the 2013
National Boy Scouts Jamboree at the Summit in West Virigina.
Wilson works at BSA headquarters in Texas and is a big
promoter of amateur radio in Scouting.
So much so, Wilson says he organized a national Radio
Scouting advisory committee last year to get stronger
support in the amateur and Scouting community for JOTA.
Earlier this year, Wilson says a member of that committee
made a suggestion about getting some additional Scouting
recognition for amateur radio.
Wilson says there were some ideas that eventually evolved
into exploring the "interpreter" strip worn on the Scout
uniform to show a Scout has some ability to speak a certain
language.
Wilson admits he came up with the idea for "Morse" on the
strip - but in the letters of the language - dah-dah, dah-
dah-dah, di-dah-dit, dit-dit-dit, dit."
Wilson says he quickly moved the idea over to the BSA's
national awards committee where it got a favorable reception
and approval within months.
So how does a boy earn it?
Wilson says there are three requirements, the first....
"It's carrying on a 5-minute conversation in Morse Code at a
speed of at least 5 words per minute," Wilson explains.
"And, then the second one, copying correctly a 2-minute
message sent in Morse Code at a minimum of 5-words-per-
minute.
"And, copying of course means writing the message down as
it's received. And, then, three, sending a 25-word written
document in Morse Code at a minimum of 5 words per minute."
Wilson says Scouts can be certified by their Scoutmaster or
maybe even a ham who's an adult Scout leader.
Wilson says the idea is to further cement the bonds of
brotherhood between Scouting and ham radio operators. And,
of course, Wilson is....
"Eager to increase participation in amateur radio to provide
an opportunity for Scouts to get involved in a fun hobby, a
hobby that promotes communicating with lots of Scouts and
others around the country and around the world," Wilson
says. "And, it's science, it's technology, it's engineering,
it's math - the stem items that are of enormous interest
right now and frankly have been in Boy Scouting for quite
some time."

HOW TO READ PROPAGATION NUMBERS
The A index [ LOW is GOOD ]
- 1 to 6 is BEST
- 7 to 9 is OK
- 11 or more is BAD
Represents the overall geomagnetic condition of the ionosphere ("Ap" if averaged from the Kp-Index) (an average of the eight 3-hour K-Indices) ('A' referring to amplitude) over a given 24 hour period, ranging (linearly) typically from 1-100 but theoretically up to 400.
A lower A-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Ap-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
SFI index [ HIGH is GOOD ]
- 70 NOT GOOD
- 80 GOOD
- 90 BETTER
- 100+ BEST
The measure of total radio emissions from the sun at 10.7cm (2800 MHz), on a scale of 60 (no sunspots) to 300, generally corresponding to the sunspot level, but being too low in energy to cause ionization, not related to the ionization level of the Ionosphere.
Higher Solar Flux generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; Solar Flux rarely affects the 30, 40, 60, 80, & 160 Meter Bands.
K index [ LOW is GOOD ]
- 0 or 1 is BEST
- 2 is OK
- 3 or more is BAD
- 5 is VERY VERY BAD
The overall geomagnetic condition of the ionosphere ("Kp" if averaged over the planet) over the past 3 hours, measured by 13 magnetometers between 46 & 63 degrees of latitude, and ranging quasi-logarithmically from 0-9. Designed to detect solar particle radiation by its magnetic effect. A higher K-index generally means worse HF conditions.
A lower K-Index generally suggests better propagation on the 10, 12, 15, 17, & 20 Meter Bands; a low & steady Kp-Index generally suggest good propagation on the 30, 40, 60, 80, & 160 Meter Bands.
