Ian, here is my thinking. When site 1 has a signal on
the repeater input, the signal from site 2 is blocked
because of the circuit that gives precedence to the
local site repeater receiver. When a site 1 user
unkeys, there will be no CTCSS tone coming back from
site 2 to key the site 1 repeater. The combination of
the precedence circuit and CTCSS requirement for both
repeaters keeps the system from locking up. The same
circuit would be required between the receivers at
site 2 as in site 1. And both repeaters would have to
be configured to only transmit a CTCSS tone when a
user keys the input, not during the squelch tail.
