The transmitters are as follows:
MAJORA – 434.211 MHz USB, 600 bps RTTY, 600 Hz Shift, 8n2 – (SSDV + no GPS)
OLAF – 434.149 MHz USB, 300 bps RTTY, 880 Hz Shift, 8n2 – (SSDV + GPS)
There may also be a backup tracker on 434.700 MHz USB.
The launch will take place from Pepperbox Hill near Salisbury, at 7am due to the NOTAM, so it will be sent up slowly, perhaps landing in France.
