Actually, that sounds like standard 2-channel, 4-wire tone remote operation to me, where it's required to listen to both channels all the time. Is there 2 rx's in this box or just one? If just one, it likely has some sort of scanner in it. An option on those was called PSLM, or priority search lock monitor. It was just a simple 2-channel scanner circuit that toggled between the two rx channel elements. I think there may have even been a 4-channel version. Also CTCSS should not have any effect on any of that, other then they probably have a CG disable circuit, which in commercial service it is required to listen carrier squelch briefly before tx'ing. It likely will toggle rx into CSQ, then back to normal after tx is keyed. -- Jim Barbour WD8CHL
