Goonhilly GHY-1 Arthur

Phil M0DNY is planning to launch a high altitude balloon or two on Tuesday,
July 10 from the Goonhilly Earth Station on the Lizard in Cornwall, nearby
to the Marconi Wireless Testing Station.

Any help with tracking would be greatly appreciated!

Were currently undecided between morning or late-afternoon. If we go for
morning then we may also launch a second later near-identical balloon later
in the day. 5m/s ascent, ~35km burst.

Two Trackers:

• Callsign: 1900 (year of construction of the Marconi Wireless Station)

Calling Beacon: 433.650MHz.100 LoRa Mode 5

Telemetry: 434.300 MHz LoRa 20.8K SF10 4/5 Explicit

• Callsign: 1901 (year of first over-the-horizon transmission received at
the Wireless Station, from the Isle of Wight)

434.100 MHz USB RTTY 50bd 7n2 480Hz

Ill post updates in #highaltitude on the day when I can.

For tuning in on the pi-in-the-sky LoRa gateway, the config you need is:

CallingTimeout=60

frequency_x=433.650

mode_x=5

AFC_x=y

Thanks, Phil M0DNY

The 434.100 MHz FSK RTTY balloon signal should be receivable across most of
the British Isles using a radio capable of SSB reception in 434 MHz. Online
tracking at https://tracker.habhub.org/

No radio? Use the SUWS online radio to receive signals from 434 MHz High
Altitude Balloons when they are range of London (select USB mode)
