CN8WW - CQ WW DX 2000 page 10 The BCC-2000 Project The idea to set up a new world record was born in 1989 after the LX7A operation was successfully completed. But: we had to wait for the peak of the next sun spot cycle which was predicted to be around the year Zone 33: can be reached by overland route, proximity to Europe, good propagation's. 1995: DL5MAE & DL6RAI are travelling to Madeira, CT3 1997: DL2NBU & DL6RAI are travelling to Ceuta, EA9; DK3GI visits the Canary Islands, EA8 1998: DL6FBL receives an invitation to Rabat/Morocco. May 1999: DJ9MH, DL6FBL and DL1MFL take part in the CQ-WPX-Contest from Morocco. September 1999: DL6FBL & DL8WPX take part in the WAE-DX-Contest and explore a new QTH. They found a new QTH (Hotel Firdaous) and checked it for a M/M operation. October/November 1999: First try to set up a new world record CN8WW.

CN8WW - CQ WW DX 2000 page 14 Logistics The majority of equipment is owned by the participants of the activity. The rest was bor- rowed from BCC members or sponsors. At three different logistic centers (Goch, Fulda und Windach) the material was collected and stored before and after the contest. We created a special numbering scheme to identify the material during packing and un- packing. Every station was planned in any detail.The bill of material contained 720 items with a total weight of 10 tons.

CN8WW - CQ WW DX 2000 page 28 BCC-standard The BCC standard was created to insure com- patibility of the different plugs and interfaces for a multi op operation.

CN8WW - CQ WW DX 2000 page 29 TS-850SAT To ensure fast replacement in case of a transceiver failure all stations were equipped with a TS 850-SAT from Kenwood. During many BCC activities this transceiver has turned out to be very reliable. From the operators or BCC members we had a total of 16 TS850-SAT during the SSB contest and 14 TS850-SAT for the CW part.

CN8WW - CQ WW DX 2000 page 30 EMC To prevent current flow on the outside of the coax cables which causes unwanted radiation and signal pick up we used current baluns. The current balun consists of 25 toroids type B64290-K618-X27 and 0,5m RG-213.We made a couple of these current baluns and used them at different points in the set ups.

CN8WW - CQ WW DX 2000 page 31 EMC Additional Measures: Low pass filter with additional notches on the higher bands developed by DL7AV/DK4VW (first version developed in 1987 for HD8EX ) 100-watt-filter (Dunestar)

CN8WW - CQ WW DX 2000 page 32 EMC In the year 1997 and 1998 we built about 100 BCC-Preselectors. Simple design, use of standard components and high efficiency are the main advantages of this device.

CN8WW - CQ WW DX 2000 page 33 headphone amplifier Enables both operators to access both receivers audio. In addition you can use it in stereo mode (means: left ear - left RX and right ear - right RX).The volume of each radio can be adjusted separately. R1= left radio on both ears R1+R2= left radio on left ear, right radio on right ear R2 = right radio on both ears

First use: WAE-DX-Contest 1998 DLØCS avoiding hot switching two modes: with/and without dot-dash memory(operator specific) combining all CW- sources (PC1, PC2, el. bug, straight key) well defined PTT- signal (start and stop)
