Mode V/U (J) FM Voice Repeater: Operational
Downlink
- 436.7950 MHz FM
Uplink
- 145.8500 MHz FM, CTCSS 67.0 Hz.
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)
1) Transmit on 145.850 MHz with a tone of 74.4 Hz to arm the 10 minute timer on board the spacecraft.
2) Now transmit on 145.850 MHz (FM Voice) using 67.0 Hz to PT the repeater on and off within the 10 Minute window.
3) Sending the 74.4 tone again within the 10 minute window will reset the 10 minute timer.
