[arm-allstar] Simplex and Allstar

[David McGough]

Kip,

I guess everyone involved with these systems are ham operators?

If they are hams, sure, a simplex solution will work fine, assuming all 
the stations participating in the net on simplex can hear each other 
directly?

There are lots of mobile radios (both ham and commercial) available with
COS signaling already provided via an accessory connector. A good solution 
here is to obtain a commercial radio surplus--such as from ebay. There are 
many radios that work well and are inexpensive.
