Radio Communications Subsystem
• 145.935 MHz BPSK Telemetry 30 or 300 mW
• Inverting SSB/CW transponder 300 mW PEP
- 435.150 – 435.130 MHz Uplink LSB
- 145.950 – 145.970 MHz Downlink USB
Passband may be up to 15 kHz higher depending on on-board temperatures
Educational Telemetry beacon is 300 mW during day and 30 mW at night.
Transponder is only active during night passes and at weekends Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna (25 w EIRP). Lower power will also work well.
If adjusting for Doppler shift manually try tuning the uplink frequency
while transmitting to keep the downlink frequency constant.
