LU6Z
South Orkney Island
The operation was
organized by this group in the Laurie Island LU6Z radio station
between 5th December, 1995 to 26th february, 1996 with the
logistic support of the National Antarctic Management and the
Argentine Navy, and also with the cooperation of Argentine Air
Force and Argentine Federal Police, and without any economical
sources from the outside and without any help from any comercial
firms of communications. With the exclusive motto in life, they
are giving to the radio amateurs all over the world the chance of
keep in touch with Antarctic radio countries.
LU6Z reached the mark of 23.559 QSOs and 140 countries.
This was made possible due to the available personal actitudes of
its operators: Hector M. OMBRONI, LU6UO and Ernesto J. DURANTE,
LU1ZPF (now LU2AS).
During the installation of the antennas they confronted against
temperatures. and severe wheather conditions, and during the
operation of the station fighted against several operative
difficulties like propagation conditions, electromagnetic storms
and the base traffic: everything together was the main reason to
become 7 Mhz the most frequent used Band.
Hector, LU6UZ and Ernie, LU1ZPF, those who were recently living a
real adventure on the Laurie Island, started their account giving
us their impression about propagation, saying that the
propagating condition in particular day, usually did not apeare
the following day, this is why in one hand in front of one Asia
opened, in the other hand it was only for a short time and not
often.
Their were desesperated when they could hear a lot of stations in
the bands but they did not get any answer to their calls. They
were earnestly seeking after the permanent sostained traffic in
any band, in spite of their former antarctic experiences, they
had to develope difterents field work technics, like band
changes, aerial changes, etc., but nothing of these methods gave
them a denouement under the DX world pressure, they only could
give the best part of themselves, staying the most time in
activity.
In one of those tentative plans to improve the available power,
Hector put two new tubes in the FL1000Z amplifier and after some
working hours, they exploted !! so they had to go back to the old
tubes.
They have several anecdotes, about how they used to sleep on the
ship floor, cause it was too crowded, they also have to take part
of the base staff, working as underloaders of the ship and also
had to do another logistic task for survival during their staying
in the island.
They saved the good climate period doing outdoor activities like
locating in due place the directional and installing between
others dipoles and wires a Hertz Zepp. aerial at the top of 30
meters high towers.
Draft Notes
Antennas: 4
rotary elements for 20-15-10 meters and 1 element for 40 meter.
Hertz Zepp. and 40 m. full wave Delta loop antennas with Swan
tunner and Long Wire with home brew T tunner 20m. slooper also.
Tranceivers: Yaesu FT101ZD and ICOM IC726 with Autek audio
filter. Yaesu FL1000Z and 2 x 813 gnounded grid home made Kw.
amplifiers. Two 30 meters high towers of the Base were used for
wire and beam antennas.
Keyers: Bencher paddles with Autek memory
and home made keyers give commfortable and smoth operation.
Their were transported in a five days trip by the Argentine Navy
Icebreaker Ship Almirante Irizar in his way to different places
in the Antarctic continent.
The 10 watts radio beacon on 28.211 Khz. with a vertical ground
plane received several reports from South America stations.
The MIR space ship was conected in 2 m. VHF band with 40 Watts
and vertical antenna. 65 SSB and CW QSOs with LUs and LZ0A
in South Shetland Is. were made using the RS12 satelite, up link
on 21.220 khz. and down linkg in 29.420 khz
