Hi folks..... I've got a quick question regarding scan lists on the PSR500 (dont have one currently but hopefully soon). I've been doing some reading and I'm trying to wrap my head around the object oriented programming vs Uniden's dynamic memory. Here is my question... On a Uniden radio such as the BC246, I can enter as many systems as I can fit in memory, 10 of which get assigned a quick key. Now I'm looking at the PSR's 20 scan lists in the same light as the quick keys on the 246. Can I store more than 20 systems into the PSR at any give time, with only certain ones assigned to scan lists? (which could be re-organized later as needed).... or am I limited to strictly the 20 assigned systems with the rest shuffled off into v-scanner land? I'm thinking the latter is likely true, which would be sort of a shame. As much as I love the features the PSR's offer, I really like how the dynamic memory works, especially being able to take a large trunking system, assigned to a quick key, then being able to sub-divide with group keys (police, fire, ems etc etc).
