+  * Switch 1 is TX audio range selection - on/up is high level for louder transmitted audio, off/down is for quieter transmitted audio
-| Yaesu FT-450D      | 0000    ^
+  * Switch 2 is RX audio sensitivity - on/up is low sensitivity for loud radios, off/down is high sensitivity for quiet radios
-| Tait TM8100 / 8200 | |
+  * Switch 3 is AC/DC coupling - normally should be off/down apart from specific radios
+  * Switch 4 is external carrier detect - normally should be off/down unless you need it for a specific purpose

+| Yaesu FT-450D      | 0000    | Requires low level TX audio - the FT-450D is very sensitive.\\  RX audio setting probably doesn't matter, control with appropriate RF gain / AGC, but off/down works. |
+| Tait TM8100 / 8200 | 1100    | Requires high level TX audio, else the transmitted audio is too quiet in the range of the pot.\\ Requires low level RX audio, else CRC is always lit. \\ Requires AC coupling to block the DC which is present on the TX audio pin. |
+| Tait T2010 | 1100    |  |
