Active Memory Save
Configure the CAT-1000B to suite your special requirements. Active Memory Save
permits you to store the current settings of the control channels, timers, codes and
the first twelve voice messages. Memory space is provided for eight memory saves.
These memory saves can be later recalled with a simple DTMF command.
LiTZ Emergency Alert
LiTZ is a new system promoted by the ARRL to provide a means for a repeater user to
request emergency assistance without being familiar with the operation of the
repeater. If a repeater user transmits a DTMF [0] for three seconds, the CAT-1000B
will alert the repeater's control operators.
DTMF Access
This feature requires the user to enter a DTMF code, to activate the repeater. The
voice will say: "OK UP" and the controller will respond to a carrier input. After a
short period of inactivity, the DTMF code will again be required.
Repeater CTCSS Override
When CTCSS is enabled, a user without a CTCSS encoder can activate the repeater by
entering the DTMF Access code. The voice will say: "OK UP" and the controller will
respond to a carrier input. After a short period of inactivity, the DTMF code will
again be required.
Monitor Repeater By Telephone
A control operator can monitor repeater activity through the telephone, join a QSO in
progress or conduct intermodulation and desensitivity testing.
Any signal received by the repeater will be heard in the phone and the control
operator can turn the transmitter on and off. If a user attempts an autopatch while
the repeater is in the monitor mode, the voice will say: "TELEPHONE LINE IN SERVICE".
The controller will suspend link operations when the monitor repeater by telephone
feature is activated.
