DLØSHF Moon Beacon 10 and 24 GHz

Information on the 10 GHz moon beacon from DL0SHF

Information on the 24 GHz moon beacon from DL0SHF

10 GHz moonbeacon DL0SHF

Status of 10.368,025 MHz transmitter

status 7-11-2022 Indicated moon beacon state seems to have a problem
Not working at the moment

Transmission sequence

Even minute:
1. :00 seconds - Transmit Enable keys up at the Tone 0 frequency,
2. then at :01 seconds the WSJT transmission starts.
3. 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

DLØSHF 10 GHz EME beacon

DLØSHF antenna 7.2 mtr dish

J054CG

Specifications

Frequency: 10368.025 MHz; GPS stabilized

Output power : 50 Watt

	DLØSHF water cooled SSPA with 50 Watt output power

Antenna: 7.2 mtr prime focus dish transmitting with vertical polarisation

Location In North West Germany

QRV: always when moon is visible with more than 10 degrees elevation at DL0SHF but only when moon declination is above 20 degrees North

Transmitting CW and JT messages

Very High Power is possible on request, mail to DK7LJ, about 750 Watt output

For RX digital mode you must use WSJT mode Q65-60E

transmitting Q65-E on even periods and CW (FSK) on odd.

Dial frequency needed is 10368.024, which will bring the upper tone of the
FSK and lower tone of the QRA at 1000Hz audio.
