There are many ways of scanning international phonecalls (in case there are people who believe that interantianl phonecalls are not traceable).HHYou need:

Alan, as I remember it, the RUS (Received Unsquelched Signal) is active only if the
Channel Guard (PL) is activated on receive. The CAS (Carrier Activated Squelch) is
active whenever a carrier is present.
It sounds to me like you have the repeater operating and only need to add a hang
time to the transmitter. This should hold the transmitter for one to three seconds
after the CAS drops. Most repeater controllers do this and have programable hang times. Are you using a repeater controller, or a homebrew COR (Carrier Op
If you are using a COR, you'll need to have the time delay added to it.

I have what may be a very unusual but interesting question. A few months ago,
I encountered a lot of talk about whether memory settings could be cloned from
one FT530 to another. I believe that the answer was yes and that it could be
done through the 1/8" jack of the spkr/mic plug. Recently, Yaesu has come out with the FT51R which is programmable (not just cloneable) through this plug
An I correct in assuming that the 51 programming software would work on the
