User Programmable Fields

Enable a User

To activate a user in the ZR310, you must enable the TPL tone or DPL code user number. The transmit radio keys when the carrier and the TPL tone or DPL code are decoded.

Set the Status line as Enable to activate a user.

Reserve a User

You may need to reserve a TPL tone or DPL code for future use. If a user keys up on a "reserved" user number, the transmitter will be keyed but it does not cut through a repeat audio. It sends a beep tone for the duration of the transmission. This mode is to disable a user for seasonal use or a possible "no-pay" condition. A reserved user will keep the tone active in the repeater, preventing other co-channel repeater operators from seeing the tone as "available".

NOTE

Before reserving a user, you must enable that user

Receive (Rx) Squelch Decode

The ZR310 can decode all 50 TPL tones and up to 20 DPL codes. The TPL user numbers are 1-50, and they have fixed frequencies. The DPL user numbers are 51-70. Each of these user “slots” in the database can decode any valid DPL code, so you must set the digital "code number". When you set the DPL decode number, the ZR310 will automatically set the encode to the same DPL code. (Refer to Table 6-3 for TPL tones / DPL codes.)

Station ID Call Sign

A station ID call sign is a Morse code ID assigned to a particular user. This ID may be eight characters long, and may be any combination of numbers or letters.

You can program an individual Morse code ID for each user number. The first time the user unkeys, the ZR310 sends the Morse code ID. If the user keys up again, voice communications may occur during the ID. The ID is sent at 30% deviation and a selectable speed from 4 to 25 (default is 22) words per minute (meets FCC Part 90 regulations). With System Programming, you can set the ID tone frequency from 400 to 2000 Hz so that it does not interface with paging or other tone signalling on the channel. You can set the ID interval from 1-99 minutes. You may also program a single System ID call sign. Refer to Table 6-4 for the Station ID Cross Reference and Table 6-5 for the TPL tone / DPL code conversions.

Transmitter Hang Time

The transmitter hang time is the amount of time the repeater transmitter remains keyed on the channel after mobile activity is no longer detected. The transmitter hang time must be set to a value between 0.0 and 25.0.

TPL/DPL Encode During Transmitter Hang Time

Normally the repeater encode signal follows the mobile encode. However, You can leave a TPL or DPL encode on during the transmitter hang time. By leaving the encode on, you can eliminate the decode time between transmissions, thus not losing any audio.

Choose Y to leave the encode on during transmit hang time, or no to turn it off.
