First of all - Thank you all very much for the advice and recommendations.
Based on my other reading and trying to educate myself it was already looking like the SDS100 was going to be the answer. A tad over what I was looking to spend when I started but it is what it is and I wasn't shocked by your suggestions when I got back here. I had already thought of the Unication route but from what I'm finding (before coming here) was they were a little more $ than the scanner route.
Next - More background on my situation (and our system):
The 154.2275 is one way simulcast (from Dispatch out) with the RVRS 401 / 191 FCFR Disp talk group just for paging and initial dispatch only.
There are still some VHF pagers in use but we have (for the most part) transitioned over to the Unication pagers and SOP is after initial dispatch, all incidents are assigned to a different talk group Ops 2-6 (402, 407, 408, 409, 416) so you won't hear anything else related to that incident on VHF. Even in the event that we contacted them on 401, you'd only hear their side of the conversation on VHF.
Now for me, I happen to have a one of the remaining VHF Minitor V's that never leaves the charger just for bed side alerting.
I have my issued APX4000 and there is also my GF's Unication G5 and her APX4000 in the house as well and you'd think that would be enough radio equipment right?
So here's the rub, my home office & the GF's are on different floors so I can't hear her pager from my office and 99% of the time the 2-ways are in radio straps in vehicles or by the door and I would prefer to keep them there. So all I really wanted/needed was something I could listen to from my office and/or the family room on the same floor. Also we sometimes fall asleep in front of the TV at night so I wanted something that could still alert and wake us up since the pagers are on a different floor.
As for the codes, etc from our radio guy, I'm willing to bet the farm that he'll give me anything I ask for short of the LE systems. The Sherriff and PD Chiefs really would kill him if he did that.
At this point I guess I'll keep tabs on some used equipment groups, keep saving my pennies, and possibly see if one of my FD's has a spare Unification pager.
Thanks again for the help. Hope you all have a Merry Christmas!!
