- Direct Function Keys Everyday functions are pre-programmed to 11 of the 12 keys. The additional PF key can be assigned a custom function, making it possible to tailor the TH-K20A for optimum convenience. There is no need to use a menu: one key push provides direct access. And to prevent accidental operation, three types of key lock are provided.
- Backlit LCD and Keypad Backlighting for the large 13-segment LCD display is a welcome feature when picking memory names or changing settings. Similarly, keypad backlighting facilitates operation in low-light situations.
- Internal VOX The TH-K20A offers convenient hands-free operation when using an optional headset. The internal VOX (voice-operated transmission) circuitry provides automatic PTT and a 10-level (Off/1-9) sensitivity adjustment to suit different ambient noise levels. VOX delay time is also adjustable.
- CTCSS & DCS Encoder/Decoder + Cross Tone Capability Thanks to the built-in CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Code Squelch) encoder/decoder, the TH-K20A can handle 42 CTCSS sub-tone frequencies plus 104 DCS codes. And one can set separate TX and RX signaling types so as to access a repeater that uses different encode/ decode signaling.
