[aprssig] Maryland, NoVa Voice Alert

[Bob Bruninga]

For Central Maryland and Northern Virginia: 

The WN3R crossband Regional APRS Voice Alert repeater is on the air from Fredrick Mountain for testing.   

The CALLER uses 445.925 T100 TX/RX and his call must contain something like "Crossband Regional Voice Alert, WB4APR listening on 146.52 TONE 100". 

This comes out on 144.39 T100 Voice alert to ALL APRS voice alert mobiles in the region.  For the mobile to get back to the caller, the mobile must respond on 146.52 with tone 100 
which then comes back to the caller on 445.925. 

So once everyone understands how this works, then it will be ideal if all Voice Alert mobiles program T100 into their 146.52 channel for ease of use. 

As with all use of Voice Alert, the only objective is to make the call and then immediately QSY to a chosen repeater.  In this case, the caller COULD also make a one-way call such as: "Crossband Regional Voice Alert, Wb4APR Listening on the 147.300 repeater".  In this case, no 146.52 call back is expected. 

I'm out of the footprint from my haunts, so I am announcing it here so that those over closer to the Fredrick Mountain can give it a try. 

Use i springly, but be thinking of how we can use this new asset.
