3-16 Customizing Channel and Frequency
Customizing Channel and Frequency
The TW7000 associates a frequency, mode, clarifier status, and offset
value (if on) to each channel number. These can be different for each
channel and are recalled whenever that channel number is entered.
Once frequencies are set to channels, channels can be placed in scan
groups.
Note: Scan groups are defined by channel number, not by frequency.
Changing the frequency of a channel also changes the frequency of
that channel within each scan group.
Channel Selection and Scrolling
Selection of a channel is done as follows:
1. Press C.
2. Enter the desired 3-digit channel number or use the arrow but-
tons to scroll through the channels.
3. To select the channel, press E. The channel number with its fre-
quency and clarifier offset displays.
Assign a Frequency to a Channel
Acceptable transceiver frequencies range from .100000 MHz to
30.000000 MHz in the receive mode and 1.6 MHz to 30.000000 MHz
in the transmit mode. Simplex operation uses identical RX and TX
frequencies and must be in the transmit mode range. Semi-duplex
(split frequency) is entered as anRXfrequencyfirstandthenasaTX
frequency. Out-of-range frequencies produce an error message and
the previously entered frequency is restored.
Entry of frequencies must always include the decimal point unless
there are all zeros after the decimal point. Entry of leading or trailing
zeros is not required.
Entering a frequency between .100000 MHz and 1.6 MHz in the sim-
plex mode causes the radio to be receiver-only (PTT inhibited).
Assigning Simplex Frequencies
To select the channel and assign a new frequency:
1. Press C and enter the 3-digit channel number and press E.
2. Press F and enter the frequency in MHz, including the decimal
point and press E. The channel number is updated with the new
frequency.
