I guess I didn't pay attention to the rx_dtcs changes to the wiki when you made them, but the "if it has rx_dtcs do X otherwise do Y" logic is too confusing.
Well ... it's exactly what we have for tones: "if radio has_ctone use X else use Y" Consistency between tones and dtcs is vital from my point of view.
From the user perspective is not that confusing: if I see only dtcs column it will be used for all if I see dtcs and rx_dtcs columns the first will be used for tx and the last for rx
Seriously, the only confusing thing I see is that we have "DTCS" mode (with a name schema similar to "Tone") and it means "DTCS SQL", if I would change something I'd rename "DTCS" to "DTCS SQL" and add a "DTCS" with the meaning of tx only.
Your move ...
