DSDPlus DSDPlus Channel Number

[slicerwizard]

I have a Hytera system here that doesn't track. This specific system broadcasts the channel and frequency, it seems the SDS100 doesn't like that

While some systems use a simple single-block voice call channel grant message that doesn't contain any frequency information (just LCN and slot), that system is using a more complicated dual-block voice call grant message that explicitly states the channel TX/RX frequencies. The firmware in Unidens simply hasn't been coded to handle it.
