The tmode of "TSQL-R"  is not documented. It appears to be used in a few drivers

to map to the Yaesu internal squelch mode of "REV TN". Is this correct? more generally, is it acceptable to add an obscure mode to the UI? I had originally added "REV TN" as a value for an "extra" memory field on the ft-4. The FT-4 has yet another "extra" sql_type called "PAGER". can I add "PAGER" to the UI tmode list instead?

I feel like both "TSQL-R" and "PAGER" should NOT be in the standard UI tmode list, but I will defer to the experts. My reasoning: the UI should remain as generic as possible to maximize

the sharing of channel lists. Treating this sutff as "extra" allows the driver implementer to decide how to handle this stuff on a case-by-case basis. I'm als not completely sure that the semantics of "TSQL-R" is the same for non-Yaesu vs. Yaesu, although I think it's the same for all Yaesus.
