APCO Project 25 Reception
APCO Project 25 is a modulation process where voice
communications are converted into digital communications.
This conversion is similar to the technology used with digital
mobile phones. There are several types of Project 25 systems
available!
- Conventional – one frequency with digital voice.
- Trunked with analog control channel and digital voice – many
frequencies shared by many departments and the control
channel is analog with digital voice. Control channel operates
at 3600 Baud.
- Mixed Mode - trunked system with analog control channel
alternating / mixing analog and P-25 digital voice
communications.
Note:
Install the APCO card face up (the side which has “APCO
P-25 DIGITAL CARD” label.)
