Operating
There seems to be a slightly different method of using this satellite (why?):
From the Amsat page:
To switch the transmitter on, you need to send a CTCSS tone of 74.4 Hz. The order of operation is thus: (allow for Doppler as necessary)
- Transmit on 145.850 MHz with a tone of 74.4 Hz to arm the 10 minute timer on board the spacecraft.
- Now transmit on 145.850 MHz (FM Voice) using 67.0 Hz to PT the repeater on and off within the 10 Minute window.
- Sending the 74.4 tone again within the 10 minute window will reset the 10 minute timer.
