Preparing for the new season, I designed and built a
vertical antenna for 160m in 3V8SF location. The
antenna is 17m high with two top loading wires 12m each.
For instance, the antenna has 8 radials, 19m each. A
shunt match coil is added at feedpoint.
Focus on 160m Receiving Antennas
focus in the last few weeks is to improve receiving capabilities on low bands
(mainly on 160). I noticed that city noise is a big handicap for working DX on
80 and especially 160.
Three beverage antennas were set up so far in 3 different locations to
assess performance and make a plan for a permanent receiving QTH were several
receiving antennas on different bearings will be installed.
I would recommend K1ZM's "DXing on the Edge" book for those who
are also became addicted to 160. It can only worsen the situation :-)
Triplexer, BPFs and 6x2 Switcher in 3V8SS
3V8SS radio station is now equipped with a Triplexer and
3 Band Pass Filters for 20, 15 and 10m. I bought the set
from Low Band Systems by RA6LBS during my visit to
HamRadio 2016 in Friedreshchfen, Germany.
The Triplexer provides 100% redundency of the high bands

During my stay in Bali Indonesia for honeymoon, I had
the pleasure to meet Made YB9AY in Sanur Area. YB9AY
Station is located in Made's house within the fences of
his hotel Wirasana Bali.
The YB guest license requires showing to ORARI Official
your Passport, a valid
license (check countries list able to have guest
licenses), a passport photo and fees of 150'000 Rupiah
(about 10 US$). Click
to see my guest license.
Propagation from this part of the world is very
different. High bands start opening in late hours of the
afternoon. QRN is relatively high. local QSOs can be
made on low bands.
I made few QSOs on Friday July 24th then decided to
operate a little bit in IOTA contest hoping for more
activity. I did over 120 SSB QSOs on 15 and 20.
Unfortunately, Made didn't have a key or cable for CW.
Made YB9AY is a keen 6m operator. He is a former ORARI
President and one of the most active radio operators
among thousands of other hams in the island.
CQ WW SSB 2014 from CN2R M/S
Jim W7EJ kindly invited me to join him in a Multi/Single
effort from his station CN2R located in Casablanca
Morocco. It didn't took me two days for me to confirm my
The team was composed of W7EJ, EA8RM, I4UFH, HB9DUR,
W7ZR, EA9LZ and myself 3V/KF5EYY.
Our plan was to use 1 Run Station and 1 Mult Station. 2
other stations can join the RUN group as in-band
stations or as additional MULT station. All the stations
were interlocked accordingly.
Antenna towers at
Jim arrived early in October and had to set up two new
towers for the MULT/In-Band Stations. The towers were
over 250m away from the shack for the stations to be
used within 20kHz from any MULT or RUN station. Rotors are driven through WiFi. Each tower was
equipped with an A4S and an inverted-V for 40.
The main RUN and MULT stations have three different
antennas on each band pointing to different directions
with selection possibilities.
Jim on RUN Station
Contest start wasn't that good but the team could
overcome the stress and enjoy. Preparations and fixing
didn't finish by contest start, Jim still had to fix
some issues with WiFi rotors.
The Partner station wasn't unfortunately ready for use.
Over 1500 QSOs were made on the
In-Band stations. The contest ended up with 9818 QSOs
and 25 million points.

3V RBN NODE SET-UP - FIRST IN NORTH AFRICA
Thanks to LA7QIA's support, I set up a Reverse Beacon in
3V8SS Radio Station. The set up
consists of an SDR-IQ by RF SPACE, CW Skimmer by VE3NEA,
W3OA's SkinScan, and a dipole antenna. I sometimes
switch it on other antennas as needed.
This Skimmer (named "3V/KF5EYY") is the first in North
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.

QRV as TA1/KF5EYY from TA1KB
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
