I made this video using recording from my last
participation in RDXC. It shows what can be done with an
SO2R set up. My set up is composed of ARRAY SOLUTIONS
device (manually actuated) and two TS-870.
YASME Excellence Award 2013 awarded to KF5EYY!
I was nominated in 2013 to be awarded the YASME
Excellence Award. Part of the price value went to
support ARAT's activities.
This is what YASME said: "Ashraf Chaabane,
3V/KF5EYY, has become an energetic representative on all
fronts of Amateur Radio in Northern Africa and globally,
presenting a positive role model for Amateur Radio
throughout the Arab world with his enthusiasm and
competitive spirit. His mission is to see the day when
Tunisia issues him that country’s first individual
Amateur Radio license. Chaabane will represent Africa as
the team leader for the African team in WRTC-2014".
I'm proud to announce that, following the past 3 years
of competition and the selection process run by WRTC
committee, I will be representing the African Continent
in the upcoming WRTC that will be held inshallah from
July 8th to 15th 2014 in Boston, USA.
I selected Hrane YT1AD to be my team mate in this
The World Radiosport Team Championship (WRTC) is held
every four years and consists of approximately 50
two-person teams of amateur radio operators competing in
a test of operating skill. Previous WRTCs have been held
in Seattle (1990), San Francisco (1996), Slovenia
(2000), Finland (2002), Brazil (2006), and Russia
(2010). You can learn more about the history and results
of previous WRTC events at www.wrtc.info.
SO2R Technique for the first time in a 3V Station
WAEDC CW was my first ever attempt using SO2R Technique. An Array Solutions
Device was kindly brought by YT1AD. Cabling the device wasn't that difficult and
it had solid performance all the contest long.
The new technique provided me with extra multipliers and QSO points and I would
expect a more extensive use of this technique in the upcoming contests.
ARAT (Association des Radio Amateurs Tunisiens) has organized a DXPedition to
Djeba Island (AF-083) in collaboration
with an Italian team led by Fred IK7JWX. The callsign
we chose was TS8-Tunisia-Italia.
The main goal of the DXPedition was to activate this
rare island and give radio amateurs a TS8 prefixe! The DXpedition was also a
great opportunity to ARAT members to get in touch with skilled operators which
will positively impact their knowledge and operating performance.
Part of ARAT Team
ARAT role was to organize the activities by aquiring
license, logistics, booking, etc. The Italian team was kind and donated a TRX
and 3 vertical antennas to ARAT Club 3V8ESG based in the Engineering School of
I arrived to Djerba island two days before the
DXPedition's end. I operated only CW and made over 1000 QSOs in 9 hours.
Propagation was excellent and was open towards JA and W/K in the same time with
only 100W and a GP antenna right on the beach.

Terrain Analysis for
Last week, my main interest was to learn about Terrain Analysis and the profiles
impact on antenna performance. That was driven by the presence of mountains
located at the back of 3V8BB Station.
At first glance it is clear that 3V8BB QTH is excellent and these mountains only
affect SA path. However, I wanted to do the exercise, come up with charts that
support this, and why not, look for improvements.
Thanks to N6BV and VA7ST for their support during the elaboration of this work
and to S56A, W1UE and K6TU for their comments and ideas
Last week I built a 3/4 WL Beverage Antenna in
3V8BB QTH. The beverage consists of about 120m length wire at 1.2m above the
ground with 2 earthing rods on both sides.
The feeding point is equipped with a 9:1 Transformer for impedance matching and
a 450 Ohms Resistor at terminating end.
CQ WW SSB 2011 and 2012 Comparaison: Deceiving propagation
This year's CQ WW SSB condx
appeared to be similar to last year's contest. However, my results were under my
expectations despite the big difference between 3V8SS and 3V8BB set up. The
pileups can't be sustained and it happened so often that I spend long minutes
calling CQ with no answer!

After the brave
Tunisian revolution, situation in 3V-land has considerably changed and many
dreamt ideas look much nearer. Over 50 political parties born and approved, time
to ham radio to attempt their chances.
The idea behind the
1st National Meeting of Tunisian Radio Amateurs came from the need to gather
efforts and keep focus on the local amateurs’ dream to have their dedicated
association that takes care of their hobby’s related issues, starting with
individual callsigns allocation to organizing DXPeditions and building a Contest
the event started 3 weeks before. Halim (operator of 3V8SS), Ash 3V8SS/KF5EYY
and Anis (Operator of 3V8ST) met several times preparing the first and the
biggest national meeting.
Nearly, everyone had also an input to the preparations and all were motivated to
make a success out of this event.
were sent to all radio amateurs, old and new, OMs and YLs. It wasn’t easy
to find each one’s contact information. At final, over 30 invitations were
issued over email, facebook and phone.
Presence was confirmed by twenty people, the crew was on time on Sunday and the
meeting started as expected at 09:30.
Most of the attendees were Tunisian youths ranging from 22 to 35 years old. We
were also glad welcoming an old man like Mr. Hafedh (Ham Radio since the 90’s)
and Mr. Zied a responsible in the National Agency of Frequencies.
The good news came from Tunis guys; we had a preliminary approval on our request
to create the Association of Tunisian Radio Amateurs (A.R.A.T). If no refusal
will be released from the ministry of interior within the coming 3 months, the
first official meeting of the association will be held at the end of July 2011.
That was the starting point of our meeting. The agenda was completely changed to
fit the news.
Discussions were focusing on the scope of work of every member of the
preliminary executive committee during these three months to prepare the first
meeting and to deal with the most urgent encountered issues.
Participants have also discussed the structure of the upcoming association and
the way it’ll be organized. All agreed on putting it as simple as possible with
possibility of extent to fit its development.
One of the major discussed points was the next step in the procedure we already
started to make pressure on the Tunisian administration in order to have
individual licenses. Several options were discussed, however, we finally agreed
on trying to work with the National Agency of Frequencies ANF to take the lead
in allocating callsigns and helping it in radio spectrum control. A workshop
will be held with ANF once we have the approval on the association.
After taking the lead in changing the political situation in the country, the
Tunisian youths are taking things on hands and are moving forward towards
building their own ham radio association which will promote amateur radio
activities in Tunisia.
Many thanks go to the Scout Group of Hammam Sousse and their responsible Mr.
Alaeddine Slimen for hosting the meeting.
today my DXCC award for 102 confirmed DXCCs. All these were confirmed
electronically via Logbook of the World LotW (See certificate at left).
Thanks to Vitor PY2NY who sponsored all the payments as money transfer
from Tunisia to foreign
countries is not possible.
The next objective will be the 150 Milestone. Paper QSL Cards will be needed to achieve the target as soon as possible.

May 17, 2010
At least one week vacation was
mandatory for me to rest from a whole year continous work. My request for
vacation was accepted and I decided to travel
to Turkey. Preparations were very quick and within 2 days I depart to Istambul.
Just before I leave Tunisia, I
gave a call to Mr.Aziz Sasa TA1E, the president of the Turkish Radio Amateur
The first three days
in Istanbul were dedicated to tourism. Then I had the
chance to meet Mr. Aziz several times and other Ham Radio friends there.
Mr. Aziz took me to TA2KA and I assisted to an emergency exercice with him where
the purpose was to transmit as much emergency messages as possible.
I was surprised
seeing how developped the emergency communication system made by Ham Radio in this country. The TRAC has a full support from the government thanks to this.
The local authorities sponsored 3 cars to TRAC which transformed it into mobile
emergency communications center.
I was also able to visit TA1KB Club station. I made a 30-minutes pile up on 20m as TA1/KF5EYY. The pile-up was big and I made around 60 QSOs.
My warm thanks goes to Aziz, Mamduh and all the other guys I met for the hospitality and kindness.
I went to the United States during the month of
February 2010 for business. Eric NM5M answered to my call in CQ Reflector seeking
radio amateurs in Texas. We met together, he was so kind and helped me
passing the exam for the US License.
During the ARRL CW Contest, Eric took me to NR5M Super Station in Hempstead, Houston
(about 4 hours driving south of Dallas). We arrived about 3 hours after the
start of the contest. We joined the team and we
activated the 10m Stations. I was running the Multiplier Station. Eric was
NR5M is a huge station
owned by Goerge having over
20 towers for antennas and 2 stations for each band. Every station is equiped
with an ICOM, Micro Keyer II, Alfa 77S Amplifier, a computer with LCD Screen,
antenna rotors and selectors for stacked antennas, etc...
