RT7000-MSOP 3-17
Programming Channels and Frequencies
The RT7000 associates a frequency, mode, clarifier status and offset value (if
on) to each channel number. These can be different for each channel and can
be viewed whenever you enter that channel number. Once frequencies are set
to channels, you can assign those channels to scan groups.
Note: Scan groups are defined by channel number, not by frequency. Chang-
ing the frequency of a channel also changes the frequency of that chan-
nel within each scan group.
Selecting a
Channel and
Scrolling
1. Press C.
2. Enter the desired 3-digit channel number.
3. Press E. The channel number, with its frequency and clarifier offset, is
displayed.
4. Use the arrows to scroll through the channel numbers.

Channel
Frequency
Acceptable transceiver frequencies range from .100000 MHz to 30.000000
MHz in receive mode and 1.6 MHz to 30.000000 MHz in transmit mode.
Simplex operation uses identical RX and TX frequencies and must be in the
transmit mode range. Enter semi-duplex (split frequency) as an RX frequency
first and then as a TX frequency. If you enter a frequency that is out of range,
an error message is displayed and the previous frequency is restored.
When you enter a frequency, always include the decimal point unless there are
all zeros after the decimal point. You do not need to enter leading or trailing
zeros.
Entering a frequency between .100000 MHz and 1.6 MHz in the simplex
mode causes the transceiver to be receiver-only (PTT inhibited).
Entering a
Simplex
Frequency
The following steps explain how to select the channel and assign a new
frequency:
1. Press C and enter the 3-digit channel number.
2. Press E.
3. Press F and enter a frequency (in MHz), including the decimal point.
4. Press E. The channel number updates with the new frequency.
Example: To change the frequency of channel 041 from 13.330000 MHz to
8.572000 MHz:
1. Press C and 041 and E.
