DLØSHF Moon Beacon

• Hardware: 7.2m diameter parabolic antenna with 50W at the Feed
• Frequency: 10.368,025 MHz ± doppler to and from the Moon
• Mode: QRA64D or JT4F, alternating with CW

• Even minute:
  • :00 seconds - Transmit Enable keys up at the Tone 0 frequency,
  • then at :01 seconds the WSJT transmission starts.
  • At around :48 seconds the WSJT mode finishes and the Tx enable line is dropped.
• Odd minute:
  • at :00 seconds Tx enable is raised and the CW starts sending
    1. its callsign,
    2. followed by two digits corresponding to the minutes of the time and
    3. three letters, consonant-vowel-consonant forming the timestamp hash.
  • The CW repeats, so the whole message is sent twice.
  • After the second CW transmission finishes, there is period of carrier for 5 seconds.
  • Tx Enable drops at approximately :30 seconds depending on the length of the hash code.

• The sequence then repeats at the even minute :00 seconds
