Well,unfortunately for me, I lack any Phase 2 capability BUT I am able to pick up the North, 42, site quite well and can hear pretty clearly a lot of Phase 1 voice. In fact, to me, often sounding better than the equivalent on the RCS! I have two identical model scanners, one monitoring the RCS and the other listening to the NextGen system. Frequently, I hear the audio from the same units on both (which, fortunately for me, I assume they will do for a little while until everybody is switched over to the new system and the reliability of same in the desired areas is proven) and the NextGen system does seem to sound better.
The West, 45, also comes in at my location albeit very weakly. In terms of reliability, the north site of the new NextGen system works best for me.
I have no luck at all for any of the other sites.
Antenna is an old government surplus broadband prototype surveillance antenna that looks like a trashcan attached to a LNA and then to a 8 way splitter feeding multiple radios. All inside my apartment.
For portable/mobile use...well that seems to be a problem with my extremely limited equipment. My old PSR-500 handheld, my oldest working P25 scanner, has trouble decoding voice with the exact same programming as what is driving the 197's. It (the 500 handheld) just has the RS 800MHz 1/2 wave antenna. I've tried the attenuator and no antenna to no avail. Same problem at work which is about 15 minutes southeast of my home. Sounds like it's having severe simulcast distortion issues that do not seem to plague my base scanners near as much. They should be nearly identical except for the antenna as they are RS Pro197's which are functionally equivalent to the GRE PSR-600's. I have yet to try hooking up the 500 to the base antenna system to see if it works better.
At home, the North site gets between S3 and S5 on my old Icom R-7000 receiver and reads as full scale on the scanners. West gets nary a nudge on the S meter on the 7000 though I can hear it and reads between 2 and a fluctuating 3 bars on the 197.
Home is a couple blocks north of Foothill Drive and close to East Vista Way in Vista. Work is between Bluebird Canyon Road and Tamara Lane also in Vista. I can hear the West site better at work but the North still seems best, at least in terms of signal level. I can decode CC data good enough to get some decent Pro96Com traffic readings at work but cannot decode voice virtually at all with an occasional syllable coming through now and then.
