NEW HF OPERATORS - THINGS TO DO

The Phone Fray celebrated surpassing 100 sessions as of last week. The event
every Tuesday evening (US timezones) is of short duration and a good
low-pressure way to get in some Phone practice for upcoming events like the
NAQP SSB contest.

____________________________________________________________________________


BULLETINS

A very limited supply of 2017 ARRL International DX Contest pins is available
from the ARRL Contest Branch. To qualify for the International DX Contest pin,
you must have completed 100 contacts in either the CW or 'phone contest
weekends -- the pin is the same for either mode (contacts with the same station
 on different bands count toward the total). E-mail the Contest Branch to
confirm pin availability. The cost is $7 (US) in the US, its possessions, and
Canada, and $10 everywhere else (postage included). If availability is
confirmed, send a copy of the first page of your Cabrillo log file with payment
 to DX Contest Pins, ARRL, 225 Main St, Newington CT 06111. Allow 4 weeks for
delivery after your order is received.

BUSTED QSOS

Rick, WW1ME, busted me on these from last time: "Scott Redd's call sign is
K0DQ, and the Maker Faire event at Friedrichshafen is not part of Ham Radio but
 a separate, concurrent event at the fairground."

NEWS, PRESS RELEASES, AND GENERAL INTEREST

Don't forget the new ARRL 222 MHz and Up Distance Contest debuting on August
5-6, 2017. This 24-hour contest has a wide range of entry categories, and there
 will likely be plenty of FM, CW, SSB, and digital modes like MSK144 and FT8 in
 use. Contacts on higher frequencies in general earn bigger points, so there
will be plenty of activity from height-advantaged locations. Check the rules
for Club and Team competitions, and requirements to register Teams before the
contest. Log deadline is 14 days following the contest.


WRTC 2018 has announced that Honda Power Equipment is a Platinum Sponsor of the
 2018 World Radiosport Team Championship. According to Chris, DL1MGB: "Without
mobile power a radio world championship would not be possible. We are pleased
to have found a supporter with Honda Power Equipment, whose technology stands
for reliability and quality." Honda EU20i generators will be used for the
sixty-five WRTC stations.


The Thursday evening (in the US) NS RTTY events are now supported by the
real-time scoreboard ContestOnlineScore.com. According to Ken, K6MR: "The
contest name is NCCC NA RTTY SPRINT from the website pull down menu. The Help
selection on the menu bar at the site will bring up a PDF file that will take
you through the setup."

Real-time contest scoreboards are being embraced by more contesters, and are
being integrated into various contest logging programs. An evolving consequence
 is that the viewing of detailed scoreboard information such as per-band
statistics, calculated rates, and so on by contest participants could be viewed
 as assistance, and not allowed in certain categories. For example, if a
competitor is increasing the number of contacts they have on 10 meters, it may
be a hint to others that the band is open. Mark, K6UFO, the NAQP RTTY Contest
Manager, published guidance for scoreboard use to the CQ-Contest reflector:
"During the NAQP Contests, viewing an on-line scoreboard that shows total QSOs,
 Multipliers and claimed score per entrant is acceptable in the Single-operator
 category. If the on-line scoreboard includes per-band QSO breakdowns, that
information is prohibited [for use by operators] in the Single-operator
category and would move the entry to the Multioperator Two-Transmitter
category. The relevant NAQP Contest Rules are 5.a)ii) and 5.a)v)." Victor,
VA2WA/VA2WDQ, notes that contests supported by ContestOnlineScoreboard.com can
be configured to omit the display of this information.


Larry, K8UT, and Wayne, N6KR, sent this via email:

Is a Flash Mob a contest?

Several weeks ago, Wayne, N6KR, of Elecraft noticed a band opening on 10 meters
 and posted a message on the Elecraft reflector proclaiming a "Flash Mob
experiment, right now, on 28.050!" Many - I counted dozens - of the Elecraft
faithful converged on 10 CW for something akin to an instant contest. No
scoring. No rules. But what a cool idea!

In a hobby that is struggling to attract young members and compete with the
Internet, instant gratification, and spontaneous participation, I think Wayne's
 experiment demonstrated a clever connection between the Internet and a ham
radio activity.

Wayne, N6KR, chimed in: "The flash mob idea went over very well with our
customers and I plan to do these roughly on a weekly basis, just when everyone
thinks the sunspots have taken their toys and gone home :)

I wasn't looking at the flash mob was as a contest, but just as an excuse to
get people on the air in a time of protracted RF drought."


VEC tests to obtain a US Amateur Radio license will be administered at the RSGB
 Convention at 1pm on Sunday, 15 October 2017. Candidates should contact
Martin, G3ZAY beforehand to arrange the details. Reasons to sit for a US
License examination include the potential to obtain reciprocal licenses in
countries that offer such to US licensees, and that US citizens without a
FCC-issued Amateur Radio license living outside the US need a US license to
operate when they are in the US. US Citizens may not use a non-US license to
operate in the US. (via RSGB)


WWV's 25 MHz signal has changed. A circularly polarized turnstile antenna is
now being used instead of the previous vertical antenna. The change was made in
 advance of next month's total solar eclipse. Comments and reports on the 25MHz
 signal are invited via email.


CubeSats are small, standardized size satellites that have been embraced by
universities and Amateur Radio purposes. Now, businesses are taking interest.
According to the Bloomberg article, in the single year of 2015 $1.8 billion was
 invested by venture capital companies in space startups, nearly doubling the
total amount spent in the 15 years before. AMSAT's Fox-1B is a Cubesat, and is
due to be launched sometime this fall. You can get involved in AMSAT CubeSat
activities by volunteering your technical and non-technical skills and time.


If you use a smartphone or tablet, please check to see if there's a software
update from your carrier or vendor, and install it. A newfound vulnerability
involving a particular Wi-Fi chipset is considered serious, since vulnerable
devices can be hacked just by being within range of a Wi-Fi access point with
malicious intent. Patches are available for Apple iPhones and some
Android-based phones.


Pat, W5THT, wanted a more detailed explanation on how to use X-QSO with a log.
Using X-QSO tells the contest scorer program to ignore the QSO for my score.
Here's a line from the Cabrillo-format file for a recent RTTY contest:

QSO: 21093 RY 2017-07-15 1828 N9ADG Brian WA W6SX HANK CA

Let's say for some reason, I messed up, and didn't think I copied the exchange
correctly. I can change the log to this (change in boldface):

X-QSO: 21093 RY 2017-07-15 1828 N9ADG Brian WA W6SX HANK CA


Flex Radio owners are busy this week with a new software release for their
rigs. The SmartSDR 2.0 release is available on the Flex Radio Systems website,
and contains the new SmartLink feature that "does not require additional
hardware, complicated VPNs or remote desktop software" to provide remote rig
access. It also supports a new N1MM feature for spectrum display.


Rules changes are in the offing for the CQ WW Contest. See the recent article
on the ARRL website for more detailed information. Areas impacted include
definitions of the "Multi-Single" class and "US vs DX Clubs", 40 meter and 160
meter band usage, and clarification on audio recording and log checking rules.

____________________________________________________________________________


WORD TO THE WISE

Orthogonal: A description of the spatial relationship of one object to
another when the objects are at right angles. For example, some hand-held
Yagi antennas for satellite operation have orthogonal 2 meter and 440 MHz
elements

____________________________________________________________________________


SIGHTS AND SOUNDS

M0JCQ visited the US and activated New Hampshire's Mt. Washington as W1/M0JCQ/P
 for 10 SOTA points. You can read about his adventure, and view some great New
England mountain pictures on his blog. Though he wasn't able to notify SOTA
chasers of his intended operation, he picked a time when there was a contest
going on 20 meters, and was able to complete the minimum number of contacts to
earn the 10 SOTA points for his activation.

____________________________________________________________________________


RESULTS AND RECORDS

The WSJT-X team's new FT8 mode was used by a number of stations in the recent
CQ WW VHF Contest. Though a Coronal Mass Ejection wiped out the bands for many
on the second day of the contest, soapbox comments were filled mainly with
praise for the mode, which was only a week old at the time of the contest!
Mike, K7ULS, responded to my request for observations on using FT8 in the CQ WW
 VHF Contest with:

"Here's how it went:

50 MHz FT8 79 Qs

50 MHz MSK144 3 Qs

144 MHz MSK144 3 Qs

144MHz CW 1 q

50 MHz SSB 47 Qs

I would have rather had more SSB contacts because of the higher rate when it's
hopping but it just wasn't there this year so the alternative was FT8 and it's
release couldn't have come any closer and it really saved a very boring and
monotonous contest using jt65. What I liked was the ability to see multiple
callers at once or sometimes they would call a few Hz away and it still would
decode in red so you wouldn't get confused by the band activity. With a contest
 situation it got pretty hectic with the 15 sec sequences but this being the
most proficient mode for conditions at least here in Utah made it fun
nonetheless."

Some US operators who qualified for WRTC 2018 traveled to Germany for the 2017
IARU to get a feel for the propagation they might experience, and to just
practice.

Accuracy statistics have been posted for the 2017 CW ARRL International DX
Contest, to go along with the Full Results, searchable scores database, LCRs,
and QST Article on the website.

OPERATING TIP

Stay Abreast of Contest Rule Changes

It's always prudent to read the rules before the start of every contest, since
contest sponsors are apt to make changes in response to new technology, new
operating techniques, or even the contesting population. You can often get a
hint of rules changes to come and the reasoning behind the changes by reading
contest sponsor blogs, posts by contest directors, and so on.

TECHNICAL TOPICS AND INFORMATION

Skimming with the Red Pitaya Hardware continues to improve. According to Bob,
N6TV: "Nathaniel, W2NAF, and Bob, N6TV have updated the document that details
everything you need to know to turn a Red Pitaya device into a six-band 14-bit
SDR Receiver compatible with VE3NEA's CW Skimmer Server and RTTY Skimmer
Server. The document steps through the procedure required to skim CW and RTTY
signals simultaneously. The Red Pitaya hardware device is available from Mouser
 for less than $400 new. Order the STEMlab 125-14 Starter Kit with the add-on
plastic enclosure. A 30mm 5V DC cooling fan is recommended for continuous
skimming."


Astron power supplies have been in production for decades. In the rare event
that you need to troubleshoot one, you might find this website of Astron Power
Supply Schematics and troubleshooting information helpful, in addition to
contacting the manufacturer. (via ARRL Collegiate Amateur Radio Initiative
Facebook Page)


A recent article in Electronic Design News (EDN) reminds of the technique of
using incandescent light bulbs as current limiters. Use cases include testing
that new power supply for the first time, plugging in a hamfest find, as a
relay-switched inrush current limiter, or even in a receiver front-end
protector.


You may know the National Institute of Standards and Technology (NIST) through
its WWV broadcasts, or time synchronization services delivered by Internet, but
 it's involved in a wide range of activities related to science and industry.
One such offering is an Internet-delivered beacon service: the NIST Randomness
Beacon. Quality randomness is difficult, and the history and development of the
 beacon offers an interesting and geeky read. By providing an infrastructure to
 securely deliver random information in a standardized format, keeping a record
 of past generated random information, and ensuring the quality of the
information, the beacon finds application across a wide range of industry and
science. In its current state, the NIST beacon uses two earth-based commercial
entropy sources. For some physics experiments relating to quantum entanglement,
 this may not be adequate. For future randomness needs, researchers are
literally looking to the stars to find non-earthbound sources.


"Modeling Bent Dipole (and Conventional) 4-Squares, with Feed Systems" has been
 published by Dan, AC6LA. According to Dan: "The page is intended for anyone
thinking about building a 4-square array or anyone who would like to do a more
thorough job of analyzing an existing array. Several sample models are
available in AutoEZ format." Dan is the author of AutoEZ, an application that
works with EZ-NEC to ease variational parameter modeling of antennas.

CONVERSATION

Operating from an IARU Headquarters Station - S50HQ

One of the entry categories for the IARU contest is "IARU Member Society HQ
Station" - these are some of the multipliers that the rest of us are looking
for during the contest. These 'stations' can have one signal per band-mode.
With six bands, and two modes, up to 12 signals can be active at once. Many HQ
stations use multiple physically separate stations, coordinated through a
network. With the big score posted by S50HQ, I asked Robert, S57AW, to share
some details of the operation. An operation of this scale requires teamwork, so
 another team member, Jure, S57XX provided these details:



S50HQ IN IARU HFC 2017

The year 2016 was quite successful for the S50HQ Team. We achieved our best
results in IARU HFC so far: the official results showed us at 5th place among
the HQ stations and the fourth place was less than 5000 points away. 2016 was
one of the rare years when the weather was in our favor, in contrast to the
others, when some locations had troubles because of the severe summer storms
with wind and lightning.

The S50HQ Team began with preparation for the IARU HFC 2017 even before the
2016 official results were announced. The team was aware that the working
conditions on the higher bands were going to be worse than year before. The
solar activity was low this year, and there were also problems with the
unstable summer weather. We had storms before and during the contest, which
caused some damage on some locations just before the contest.

Over the past few years, the team has learned that even though Slovenia is
small, the band conditions can vary a lot between different locations on the
edges of the country; therefore, the team tried to find two most distant
locations for every band/mode combination. One of the locations represented the
 RUN station and the other the S&P in-band station. In the case of bad weather
conditions or technical problems, the stations would change their roles.

Further, the team tested different options of the networking over the internet.
 It also made a few interlock devices that enabled the lockout of the one
station when the other station was transmitting on the same band/mode. After
some testing, a VPN network worked perfectly for the entire contest. One server
 took care of six independent band networks, all stations used N1MM Logger+,
there was an interlock enabled between the stations on the same band/mode.

For up-to-date information and the exchange of operator opinions an e-mail
reflector was planned, and the team met twice in order to solve the problems
and dilemmas easily. There was a final analysis planned as well as an internal
award ceremony for stations that made a certain number of contacts with the
S50HQ station. During the weeks before the contest, the technology was proven,
especially concerning updates to N1MM Logger+. The team wanted to make sure
that the new version worked as it should and that nothing had been broken with
updates.

The competition took place from 19 different locations in Slovenia (picture).
There were 46 different operators who participated in different teams. Beside
RUN and S&P locations, there were two locations for filling band map on the SSB
 locations. The conditions were bad. There were storms that caused problems
with the reception and high QRN. A couple of locations had problems with the
internet, but overall, despite these conditions the contest was successful.

Our team's reported score is 3.4 million points less than the previous year;
however, the team will have to wait for the final result of the committee. The
participants agreed that the approach, which was used this year, works. In the
future, there should be more suitable locations, more antennas and more testing
 before the beginning of the contest. The team has gained a lot of useful
knowledge, also what needs to be improved until the next year.

Thank for all QSOs with S50HQ!

For S50HQ Team: Jure Vranicar, S57XX

That's all for this time. Remember to send contesting related stories, book
reviews, tips, techniques, press releases, errata, schematics, club
