MM-014763-001, Rev. G lid. Several different types of external-mount antennas are approved and available for use with the radio, as listed in Table 1-1 (for VHF radios) and Table 1-2 (for 700 and 800 MHz radios), and in Table 4-7. Front-mount and remote-mount M7300 radio configurations are available. In the front-mount configuration, the control head is an integral part of the mobile radio.
MM-014763-001, Rev. G employed in a mobile radio installation, an audio amplifier in the head drives the speaker. When the handheld controller is employed, an audio amplifier in the remote-mounted mobile radio drives the speaker. For data communications, the radio has an industry-standard 9-pin serial interface port for connecting optional data-type equipment, such as a Mobile Data Terminal (MDT), a laptop PC, an external display, or a key-entry device.
MM-014763-001, Rev. G EDACS and ProVoice trunked radio networks employ analog FM and 2-level Gaussian Frequency-Shift Keying (GFSK) modulation techniques on the RF channels. Data is transmitted on an RF channel at a 9600 bits-per-second rate. For over-the-air secure radio communications, the M7300 mobile radio may be equipped for 64-bit DES (Data Encryption Standard) encryption or 128/256-bit AES (Advanced Encryption Standard) encryption.
