[BC] WLS dead cxr prob. this a.m. at ~6:50

This is one of the reasons I prefer vertical polarization on STL's (especially
950). Much less inversion problems, because your signal isn't running parallel
to the ground.

That's the beauty of the GSC3000.  When the signal strength on the STL goes 
below a certain threshold, a macro is triggered to dial the back-up codec 
and then put it on the air automatically before the STL fades.  In your 
case Warren, switch to the 8K loop if both STL's fall below a certain 
signal level.

When I'm done at one site here shortly, T-1 stereo, diversity antenna 30 
mile Moseley Starlink, and Tie-line.

Adding the T-1 will be a bit convoluted as it will be the main, switching 
to the STL when the T should fail....which we know it will.  The key is 
making the macro smart enough to "know" when to activate the 
Tie-line.  Just coding in the macro....

Cheers...
