When the receive frequency is changed, the transmit frequency shall be set equal to it, easing normal
simplex channel entry. Entering a receive frequency between 108 and 137 MHz or between 225 and
400 MHz shall automatically change the modulation type to AM, unless the modulation type is P25 or
TRK. Entering any other receive frequency shall force the modulation to FM, unless the modulation type
is P25 or TRK. Frequency entry shall be accomplished via the Frequency-Entry dialog depicted in Figure
93.
CTCSS tones shall be displayed using their 2-digit EIA code. DCS tones shall be displayed as a 3-digit
number, padded with a leading zero if required. The word “None” shall indicate no tone is in use. The
Tone fields shall only be visible when the channel type is “FM”. Tone entry shall be accomplished via the
Tone-Entry dialog depicted in Figure 94.
Encryption keys shall be displayed using their alphanumeric identifier. Encryption key entry shall be
accomplished via the Key-Selection dialog depicted in Figure 25.
6.4.1.7 ATC COM Mode
When a transceiver is operating in ATC-COM mode it behaves similar too, and has all the functionality of,
previous generations of Cobham (Wulfsberg) COM radios, such as the CVC-152/CVC-151 and CD-
5000/RT-5000. This includes frequency tuning limited to the AM COM bands. The following sections
describe operation in ATC-COM mode.
6.4.1.7.1 Changing Frequencies
When the unit is operating in ATC-COM mode and standby tuning is enabled and the operator presses
the Transfer-Button the active and standby frequencies shall be swapped, and the active transceiver
