| 6 | ## Squelch (Tone, etc) |
||
| 7 | |||
| 8 | With no specific signaling, "Carrier Squelch" is used (sometimes shorted as CSQ). In CHIRP, this is represented by an empty Tone/TSQL column |
||
| 9 | |||
| 10 | The following are interchangeable terms for tone-based squelch signaling: |
||
| 11 | |||
| 12 | - Tone/TSQL (CHIRP) |
||
| 13 | - CTCSS (Continuous Tone-Coded Squelch System) |
||
| 14 | - PL (Motorola Private Line) |
||
| 15 | - QT (Quiet Tone) |
||
| 16 | - CG (Channel Guard) |
||
| 17 | |||
| 18 | The following are interchangeable terms for digital coded squelch signaling: |
||
| 19 | |||
| 20 | - DTCS (Digital Tone Coded Squelch) |
||
| 21 | - DCS (Digital Code Squelch) |
||
| 22 | - DPL (Motorola Digital Private Line) |
||
| 23 | - DQT (Digital Quiet Tone) |
||
| 24 | |||
| 25 | ## Mode |
||
| 26 | |||
| 27 | - FM: "Wide" FM for two-way communications (i.e. 5 kHz deviation) |
||
| 28 | - NFM: "Narrow" FM for two-way communications (i.e. 2.5 kHz deviation) |
||
| 29 | - WFM: "Wide" FM for broadcast communications (i.e. ~100 kHz deviation) |
||
| 30 | - AM: "Narrow" AM for two-way communications (i.e. aircraft band in the US) |
||
| 31 | - DV: Icom's digital D-STAR mode |
||
| 32 | - DN: Yaesu's SystemFusion digital voice mode |
||
| 33 | - USB/LSB: Upper or Lower Sideband |
