• Lowbands:
  • Verticals on the beach
  • Shack in the Hotel‘s conference room

   

• Highbands:
  • Towers on the hill, Beams on the towers
  • Something like a shack close to the towers

• Beverages on the hill
• Connecting both shacks by Ethernet

• 98% of all QSOs with Europe/JA (30°) and North America (300°):
  • Both directions equally important.
  • Beam headings 90 degrees off.
  • All bands open into BOTH directions for several hours per day.
• The other 2%“ are the multipliers

• One tower per band
• Three monoband antennas per tower:
  • (1) Top antenna fully rotatable
  • (2) One antenna fixed to the U.S.A.
  • (3) One antenna fixed to Europe/Japan
• „Stackmatch“ capabilities on all antennas

• 40m: same concept as High Bands:
  • (1)Cushcraft 40-2CD @ 30m fully rotatable
  • (2)Cushcraft 40-2CD @ 20m fixed to Europe
  • (3)2x 2-ele-array fixed to the U.S.A. on the beach

   

• 80m:
  • Four-Square on the beach
  • Sloper as backup antenna

   

• 160m:
  • Inverted-L on the beach
  • Dipole as backup antenna

  Beverages:

• The DL6RAI Beverage Box: Six in / Three out
• Maximum of six Beverages
• Maximum of three bands can share all Beverages
• Completely independent: any combination allowed
• Questions? [email protected]
• There is a re-design running...

• Packet:
  • First idea: PSK31 link into Germany (cancelled).
  • Dial-up Internet Account for a 48 hour Online session to the European cluster network.

   

• HF:
  • Tests showed enough in-band isolation on 10, 15 and 20m - within the 500m-rule.
  • High Band Transmitting antennas are horizontal, thus multiplier antennas should be Verticals.
  • Multiplier station placed down in the lowband shack.
  • No Transmitting, only searching for mults and verifying incoming packet spots.

   

  MULTIPLIER CONCEPT LOW BANDS

• HF:
  • Tests showing too much RF in the 500m circle.
  • Most Low Band Transmitting antennas are „vertical“; no good supports for horizontal, yet efficient, antennas.
  • Instead we placed a second receiver (Drake R4C) on each operating position - to be used by a second OP during the non-transmit sequences of the main station).
  • R4C using same antennas as main station (3 dB splitter)

   

  NETWORK / SOFTWARE CONCEPT

• K1EA‘s CT v9.27 (!) and MS-DOS 6.22 on every computer in the network.
• Win95/98/NT machines got a clean MS-DOS boot diskette.
• Ethernet adapter with Packet drivers and K1TTT‘s newest NETTSR on every PC.
• External keyboard and external VGA monitor on every notebook.
• Internet Gateway:
  • LINUX computer
  • 14.4 kbps modem
• CLX software (by DL6RAI) running on the same LINUX computer
• CLX filters out multiple spots and only forwards „good“ spots into the Ethernet network.
