Good to hear, and the only way to find what works for your needs is trial and error. If you do put the Trunking and Conventional in one Favorite List, set the System Hold time to 0. Might optimize the speed for you.The sticking point for me was not understanding the difference between a Favourite's List QK and System QK. I didn't realize that Favourites Lists are "above" the System in memory hierarchy. I also didn't realize that I could have multiple "systems" active at the same time in one FL. That was very counter-intuitive to me.
A very real case for me is my local community, where every small town has its own police department and fire department. There are still a handful of VHF-HI and UHF conventional channels (FD mostly), plus about 10 talkgroups on one site on the statewide trunking system. Those are the ones I always want to monitor. It seems as if I could put both the conventional channels and trunked TGs into two "systems" in a Favorites List. The downside to that, though, might be it takes so long holding on the control channel I won't catch a call on conventional.
I'm re-working my lists now based on the info here and will post once finished. The next issue is how QKs work with Number Tags, so I can quickly go right to one talkgroup or conventional frequency.
