Actually, no, you are NOT required to run PL. You are required to run
some form of input protection - in other words, not operate carrier
squelch. That may be PL, DPL, NAC, or some other system that will
prevent an un-intended carrier to key up the repeater. For a RTTY
repeater, that would most likely be Mark tone. Back when 146.70 (and a
few others) were operating RTTY, you could not key up the repeaters
without Mark tone. There are several analog repeaters that use
something other than PL or DPL for input protection, and of course none
of the digital repeaters are using PL.
BTW, it's 220 SMA (not 220-TASMA). I was a 220 SMA co-ordinator for
many years.
