LEM144 DXpedition Equipment
December 2nd - 10th 2000

by Mika Mäkeläinen

On the right you can see Mika's JRC NRD-545 DSP. In addition, Mika had an NRD-535D - on loan - 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 designed by Roland Sandberg to select the antennae and, if necessary, to split a particular antenna between the two receivers. An "active splitter" was used to divide some essential antennae between the listeners.

Just like last year, the Lemmenjoki QTH was this year equipped with 14 beverage (terminated) or longwire antennae (not terminated). 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

- North (Alaska, Hawaii)
- Far East (Japan, Koreas) at direction 55 degrees
- East Asia (China, Taiwan, the Philippines) at 65 degree

The recording equipment also merits a note. Mika used only minidiscs (Sony MDS-JE520 deck and a portable Sony MZ-R35) and recorded some 50 minidiscs (roughly 125 hours). Jim still relied on portable cassette decks.
