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 VFO mode.

Press CALL to display the current calling frequency. The frequency (such as 146.520) and 9 appear. Press CALL again to return to VFO mode.

To change the stored frequency, select a new frequency, then press F+ CALL (CM).

While scanning memory channels, you can skip channels you do not want to receive. You cannot use this feature for normal frequencies.

To skip a channel, select the channel in memory mode, then press F+M (SKIP). o flashes. Press SC to scan memory channels. You can also skip a channel when the transceiver stops while scanning by pressing F+M (SKIP). The transceiver resumes scanning after you press F+M (SKIP).±

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 repeater.
