ARLA/CLUSTER: Reino Unido: Radio-balão a ser lançado amanhã vai emitir em 5 frequencias

[João Costa > CT1FBF]

Five frequencies on Friday's balloon flight

Radio amateur *David Akerman M0RPI* will launch his 'Superman' Raspberry Pi
balloon on Friday, September 12 between 11am and 12pm. The signals should
be receivable over most of the British Isles

These frequencies will be used:
- LEX 434.400 MHz, 425 Hz shift, 50 baud, 7 N 2
- KALEL 434.420 MHz, 470 Hz shift, 50 baud, 8 N 2
- CLARK 434.435 MHz, 880 Hz, 600 baud, 8 N 2, SSDV
- LOIS 434.465 MHz, 470 Hz shift, 50 baud, 8 N 2
- OLSEN 434.480 MHz, 880 Hz, 600 baud, 8 N 2, SSDV

SSDV stands for Slow Scan Digital Video.
KALEL is in Superman's body and will track his descent after he is ejected
from the main payload.

LEX (appropriately) is doing the cutting down, and has extra fields in the
telemetry for the cutdown readiness and status.

Currently ejection altitude is 28 km and expected burst is 33 km.
