The parameters of the channels table are reported in the following table.
Channel name
Channel present Presence of the channel
Channel enabled Enabling of the channel
TRX Mode
Indicates all of the possible transmission mode allowed: Analog,
compatible with ETSI standard, compatible with Motorola terminals
Channel spacing [KHz] Allows to choose the channel spacing: 25KHz, 20KHz, 12.5KHz, 10KHz
TX Frequency [KHz] Transmission frequency
Primary RX frequency [KHz] Receiving frequency of the primary receiver
Secondary RX frequency [KHz] Receiving frequency of the secondary receiver
Tertiary RX frequency [KHz] Receiving frequency of the tertiary receiver
Simplex frequency shift
If set, when the TX is active, the RX frequency is shifted to avoid
interferences. This is meaningful only for simplex operating mode.
TX power [W] Transmission power
Maximum continuous transmission
[s]
Maximum time allowed for continuous transmission (if 0, this option is
not active)
Transmission closure delay [ms] Time before carrier off after the end of the communication
TX DCS code [oct] Allows to choose a DCS code to transmit (Octal notation)
RX DCS code [oct] Allows to choose a DCS code to receive (Octal notation)
TX TCS frequency [Hz] Allows to set a subaudio tone to transmit
RX TCS frequency [Hz] Allows to set a subaudio tone to receive
RX emergency TCS frequency [Hz] Allows to set an emergency subaudio tone to receive
RX TCS hold time [ms] Time before TCS off after the end of the communication
Subaudio tone deviation Subaudio deviation
Superaudio frequency [Hz] Superaudio frequency
RX squelch level [dB] Allows to set a squelch opening level
RX squelch Hysteresis [db] Difference between squelch opening and closure levels
