[ScanIndiana] RE: SAFE-T system in Indy and BC296

[Results Not Typical]

So, then how do GRE scanners do CC only trunking
without the need for a plan? It doesn't follow either
one of your two ways...you don't need the rest of the
freqs...all you need to do is put the CCs in like
regular FM, change the mode for each CC to MO and set
the bank to MO, and press scan...anyone on the list
know why the GRE's have a better way?
