Xatcobeo transmits in 437.365 MHz , this frequency was coordinated with IARU to avoid interferences with other satellites in the Amateur Satellite Service. The modulation used by the TTC subsystem is FM with FFSK/MSK at 1200bps in the baseband. One cycle of 1200Hz represents a logic ‘1’, one-and-a-half cycles of 1800Hz represents a logic ‘0’. Output RF power is 27 dBm. A Turnstile antenna is used on-board.

Xatcobeo ModelCW beacon: Xatcobeo transmits a CW beacon every 75/150 seconds and may transmit housekeeping (HK) frames (see next section) intercalated between beacons if TM is activated. CW is transmitted at 20 WPM as an 800Hz audio on-off keyed signal in FM. CW beacon can contain different parameters: battery voltage (V), signal received (dBm), temperatures (c, Celsius degrees).
