The calling-frequency memory location lets
you quickly jump to a specific frequency. The
preset calling frequency is 146.520 MHz in
the VHF band and 446.000 MHz in the UHF
band. You can store a different frequency
into this memory, as well as other settings
associated with that frequency, such as the
repeater offset and CTCSS tone. You can
use this feature when the transceiver is in

Your transceiver can transmit and receive a
low-level, selectable subaudible tone at the
same time as it receives (RX) or transmits
(TX) a regular signal. This special tone lets
you listen only to other radios set to the same
tone frequency when you use the transceiver
in simplex operation. The CTCSS feature
also lets you match your HTX-420 to the
subaudible tone frequency used by a local
