MULTI-NET AND CONVENTIONAL MODES

MULTI-NET AND CONVENTIONAL

MODES

General

This transceiver can operate in both the Multi-Net and conventional modes. Each selectable system can be programmed for either type of operation. The type of operation that is programmed is determined by the type of radio equipment in use in the radio system you are accessing. You can probably assume that Multi-Net operation has been programmed unless you are told otherwise. The differences in operation are described in the information which follows and also noted elsewhere in this manual as required.

Channel Monitoring

In the Multi-Net mode, channel monitoring is performed automati- cally by the transceiver. In the conventional mode, it must be performed manually as described in the “Monitoring Before Transmitting” descrip- tion which follows.

Supervisory Tones

In the Multi-Net mode, supervisory tones indicate clear-to-talk and out-of-range conditions. In the conventional mode, a busy condition is detected by manually monitoring the channel, and an out-of-range condi- tion probably exists if you are unable to get a response from the party you are calling.

Group Select

In the Multi-Net mode, the group key selects ID codes; in the conventional mode it selects radio channels.
