Make sure you Full PL BOTH tx and rxers. I have had great luck with this
method. At least with the Motorolas I use as soon as the input signal is
dropped, the no squelch tall...and therefore no constant keying.

Kinda.
First... the idea Matthew offered will work. CTCSS on user signal received on
both repeaters. Kinda.
Problem: ID's. The RICK isn't properly ID'ing the "link" transmitters.
Many of us have been down this path on the list. It'll lead to an annoying
discussion of Part 97 if we go too far down that road. But you DO need to ID
every transmitter. 'Nuff said.
Best way: Put a dedicated link TX/RX at each repeater site or some sort of VoIP
linking on its own controller port. In-band RF linking on the user input
frequencies is a kludge at best. It can double with users, and has other
timing problems...
If you MUST link in-band, make the link margin (RF power) high enough that if
the link doubles with someone, the LINK wins and captures the repeater receiver
well enough that at least one of the transmissions can be heard by all...
