15 frequencies are listed there, although I don't think I have heard any activity on 5 of them (935.225, 935.250, 935.6875, 935.6625, and 935,675). The other 10 frequencies listed there I definitely hear regular Delta traffic on (DMR mode) when I listen in conventional mode, but I haven't been able to track the trunked system or capture correct LCNs.
