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!

- When will the FT1D be available? Well one Japanese retailer indicates that it could be another six months, see

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.
