Don't know yet Mike, this thing is so quiet that the only transmissions have been on the one frequency and being TIII it take a bit if a pattern to establish things. It appears to be a 2 site system, the second site perhaps in Port Colborne based on TAFL data. The CC on 169.965 appears to be freq. 1 so the #1st LCN. All DSD+ has shown me so far is "4, 5, 6, ?" for channel assignments, and no numeric data that would normally accompany a TIII system. Since the only other traffic (voice & LRRP) has been on 159.975 I'm assuming that would be the 2nd frequency, but that's purely speculative. so I'm calling it "A" second frequency vs. "THE" second. I've also monitored 169.590 (licensed to the same user) and it shows as a DMR BS, with data every few seconds but no evidence of voice traffic or multiple channels. Other licensed freqs per TAFL 168.435, 164.415 and 140.385 are silent from my QTH.
