LEM132 DXpedition Equipment
November 15th - 22nd 1999
by Mika Mäkeläinen
Below you can see Mika's
JRC NRD-545 DSP. In addition, Mika had an NRD-535D
and Jim two pieces of NRD-535D. Two receivers come
in handy especially when hunting stations which
have local identifications relatively rarely. RAI
(Italy), all Spanish networks and NHK-2 (Japan)
stations are good examples of this.
Additional equipment included
amplifiers and antenna tuners. Both had a switchboard
(picture below) designed by Roland Sandberg to select
the antennae, and if necessary, to split a particular
antenna between the two receivers. A new active
splitter was used to divide some essential antennae
between the listeners.
This year the Lemmenjoki
QTH was equipped with 14 beverage or longwire antennae.
Both users can exclusively have five antennae and
the remaining four are divided with a splitter,
so that in effect both listeners can choose between
nine wires. Each antenna is 0.8 - 1 kilometer (0.5
- 0.6 miles) in length.

Because of the reindeer, antennae
need to be 3-4 meters above the ground. Whereever
trees are not available, poles have been erected.
Antennae are directed at the following areas:
- Southern part of South America (Brazil, Uruguay,
Argentina, Chile), Spain and the United Kingdom
- Northern part of South America (Venezuela, Columbia,
Ecuador) and the Caribbean
- Eastern Coast of North America and Central America
- Rocky Mountains
- West Coast of North America
- North (Alaska, Hawaii)
- Far East (Japan, Koreas) at direction 55 degrees
- East Asia (China, Taiwan, the Philippines etc)
at 70 degrees
equipment also merits a note. Mika used only minidiscs
(Sony MDS-JE520 deck and a portable Sony MZ-R35),
which was a revolutionary improvement to the cassette
era. Jim still relied on the cassette decks, because
they operate well also at his summer cottage, which
has no electricity.
