Each System or channel is an "object" ,so if you name an object a said City like I do you can enter all the frequencies for that city in the one "object".
Mine looks like this :
1.My town aka SCANLIST 01 (has 23 frequencies all analog) (OBJECT)
2.Next Town aka SCANLIST 02 (has a trunked Sytem and some analog frequencies) (OBJECT)
3.Neighboring town aka SCANLIST 03 (has digital frequency P25) (OBJECT)
You can review the OBJECTS you programmed in BROWSE OBJECTS.
1,2,3 is its own "object " each town is a scanLIST and can be toggled on and off.
You can do the exact same thing in the Uniden 436HP,I had both scanners,I prefer the Whistler's bigger display.Digital makes everything different.Theres no more separate frequencies,except in each Scanlist even the Uniden has scanlists,so you are stuck thinking like this.
EZscan is a program thats on the scanner's SD card and if you have a PC,its easy to program!
If you have a MAC,you are out of luck unless you have Windows as a secondary OS.
If you are totally baffled Im a ham too,good on QRZ
