I'm headed to Vegas in a few weeks and have a few questions. I'll be bringing my PSR 500 and would like to listen to these two systems. I'll be staying somewhere on the strip. Most likely the southern end. On the SNACC system how many freq. do I need to program in? Can I just program in site 001 Las Vegas or do I need other sites. Same question for the NSRS system. I mostly want to listen to fd's on the SNACC and the highway patrol on the NSRS. I see there are multiple sites listed under Las Vegas on that system. That's why I'm a little confused. My other question is, what are the best tgid's to program in. I see there are quite a few and some probably aren't worth the time such as all the tac channels. My last question is, as far as other pd's and fd's such as North Las Vegas and Boulder ect, will I be able to pick these up or should I not bother with them. I know there are alot of questions that I'm asking but if I don't ask them then I don't know if I could figure it all out by myself. Thank you in advance for any responses!
