Mike - don't be scared of the dma.
Maybe this will help from a conventional programming standpoint - whereas previously you used a bank/channel setup (or scanlist/channel in modern RS terms), with Uniden's DMA, a new wrinkle has been added: groups. Oh, and instead of bank or scanlist, Uniden uses the term "system".
Basically, the setup is essentially this:
Systems > Groups > Channels.
The rule here is that you must have at least ONE group into which you program your channels per system. If you did this with only one group, that would be the closest emulation of the old bank/channel setup.
Should you need a little more organization, you can start using more than one group.
Unlike the old days, toggling these banks/scanlists/systems on and off is done with a user-defined "SQK" key of your choice - unlike the hard-coded keys that manufacturers forced you to use in the past. Reconfiguation on the fly is a snap - no more cut-n-paste to move things around!
In addition, if you have more than one group, you can assign "GQK" keys of your own liking to toggle groups on and off within that system. And of course at the very end you can do temporary or permanent lockouts of channels.
Sometimes coming from 25 years of the old-school, perhaps just using one group per system is the easiest way to start if you want to emulate some of your old scanner setups.
As you gain experience, some of your simple systems might never need more than one group. With more complex systems, the question you ask yourself is "Do I want to create another group within this system", or "Should I just go ahead and create another system instead?"
This is probably too much already, but also be sure to see this:

Don't try to understand it all in one day. Sometimes it takes two.
Seriously, there are so many options it can seem very daunting, but just concentrate on what you need to know NOW, and then pick up the rest little by little.
