Mode | ASCII | Description |
Transmit | [Spacebar] | Space must be received at least every 500 milliseconds |
Receive Mode | [None] | If nothing is received or the transmit times out after 500 ms, unit goes into receive mode |
-CTCSS In | A[tone]; | Tone must be numerical ASCII with decimal point indicating CTCSS receive tone required to unsquelch |
-CTCSS Out | B[tone]; | Tone must be numerical ASCII with decimal point indicating CTCSS transmit tone |
+CTCSS In | A[tone]; | Tone must be numerical ASCII with decimal point indicating CTCSS receive tone required to unsquelch. "0" disables mode. |
+CTCSS Out | B[tone]; | Tone must be numerical ASCII with decimal point indicating CTCSS transmit tone. "0" disables mode. |
+CTCSS Enable | C[state]; | Turns on CTCSS mode (analog tone) with 1, off with 0. |
+CDCSS Enable | D[state]; | Turns on CDCSS mode (digital tone) with 1, off with 0. |
+Bandwidth | E[mode]; | For 12.5KHz mode: 0, for 25KHz: 1 |
+Frequency | F[freq]; | Set the frequency in KHz. If offset is disabled, this is the transmit frequency |
+CDCSS In | G[code]; | Code must be a valid CDCSS code |
+CDCSS Out | H[code]; | Code must be a valid CDCSS code |
+Print Config | I | Print out all configurations in comma delimited format. |
+Power Level | P[level]; | Set power amp level, 0 = lowest, 15 = highest |
