Gee, I wonder how the repeater notes that? Suppose it doesn't care? It
doesn't....

Yes it would. However, it would be a lot more expensive than this one. This
one works, as I and many others have used it over the last 15-17 years to
access a repeater. I've got Comm Spec PL encoders/decoders and they work
without a flaw. But you pay for that quality...

Mars? I'm on earth...
