I wanted to add some channels to my favorites through sentinel for my sds100. What I did was use a SDR with DSD+ and plug in some hits from that. Frequencies, tg depending on what signal showed up. When I imputed in sentinel and up loaded to the scanner, the frequency would hit but would not scan. It would stick on that channel. Is there a tutorial out there that would help. At this point, my SDR donagle connected to the pc gets more action than my sds100. Any advice. Dave.
