I never said it was - in fact I've made that point several times on various pages on the repeater-builder web site. But if you have two systems that normally can't hear each other, but once in a while a band opening allows it, then you have to assume that the coordinators did the best job that the could given the environment. The system owners shouldn't be running a carrier squelch system, or if they are, have PL decoders installed that can be enabled. One of the local carrier squelch systems have an 82.5 decoder, and the club newsletter plainly says something like "Our club repeater is carrier squelch on (frequency), however circumstances may require a 82.5 tone. We suggest that you program your radio for full time 82.5 encode." My prior statement was made from the assumption that both were established and coordinated systems. I said that if they are going to be there, that they can at least NOT have the output tone of one be the input tone of the other. Mike WA6ILQ
