Thank you for reply below. One last question. I see how the ToneSql can be enabled or disabled in the Tone mode selection now. This allows either Tone, None, or ToneSql to be selected. If the Tone Mode column enables or disables the info in the Tone and ToneSql columns, I can see how you could enable one or the other using the drop down menu selections (Tone, None, ToneSql). If needed, how would you enable both Tone and ToneSql for a given frequency?
If you mean for split-tone operation, you don't. The two values are stored so that you could switch from one tone to the other quickly in the field, but there is no way to use a separate tone for transmit and receive. Other brands of radios have this ability, but most amateur Icoms do not.
Just for clarification: Tone mode implies just the Tone field is used for transmit, no squelch tone on receive. TSQL mode implies that the ToneSql tone is used for _both_ transmit and receive squelch.
