CHIRP Programming Cheat Sheet
What each CHIRP column means when programming Baofeng, BTECH, Retevis, and other radios.
| Column | What to enter |
|---|---|
| Location / Name | Short label — include call, tone, and mode (e.g. W4TRC 146.970 123.0). |
| Frequency | Receive frequency in MHz — for repeaters, this is the output you listen on. |
| Duplex | Off = simplex. + or − = repeater offset. GMRS usually + 5 MHz. |
| Offset | 600 kHz (2m), 5 MHz (70cm/GMRS), or 0 for simplex. CHIRP may auto-fill from duplex. |
| Mode | FM for voice. NFM on some DMR/analog rigs. Ham digital modes use other software. |
| Tone Mode | Tone = CTCSS encode+decode. TSQL = encode only. None = carrier squelch (CSQ). |
| RTone / CTCSS | Receive tone — must match repeater unless CSQ. Common: 88.5, 100.0, 123.0, 131.8, 156.7. |
| TTone | Transmit tone — usually same as RTone for repeaters. Some systems use different in/out tones. |
| Dtcs* | DCS digital codes — only if repeater uses DCS instead of CTCSS. |
| Skip | S = skip channel on scan. Blank = include in scan list. |
| Power | High/low — match legal ERP (FRS 2 W, GMRS per channel limits, ham per license/class). |
| Comment | Freeform — net times, OPEN/closed, linked system notes. |

Quick workflow
- Download stock image from radio → save backup first.
- Add simplex calling freq (146.520, 446.000, or GMRS Ch 22) as row 1 for testing.
- Program repeaters: RX = output, duplex +/−, tone from RepeaterBook or East TN sheet.
- Upload to radio → test on low power before high power.
