The station is built up to its final state before
every contest. The only fixed installations are the
towers and some amplifiers. Most of the radios and computers
are brought on site just before the contest. This is
a risky business - but so far we have managed it quite
well.
The antenna work does
not ever stop. All antennas are made by Finnish Antenna
Ltd and new ones are constantly developed and tested
at OH2U. Here is a snapshot of what we are currently
using.

The FT-1000 series by
Yaesu have become a standard for us. We have just became
familiar with them and it simplifies maintenance and
installation work to use just one model in multi/multi.
The only exception to this is the two TS-850s which
are preferred by the 80 meters operators
Most often we are using:
8 x FT-1000MP/MkV/Field
2 x TS-850S
+ home brew amplifiers

We have two PCs on each
band – one for the pileup operator and one for
the multiplier operator. In addition to this we have
a dedicated PC connected to different Telnet clusters.
We have also a connection to a 2m packet cluster. We
use CT logging software by K1EA which we have had running
on Ethernet network since 1997. There is also one Wireless
LAN link (2.4GHz) connecting the 10m operating position
to our backbone.
