Noticed this morning that the Dripping Springs site is broadcasting a different RFSS/Site ID of 151/01 (decimal) instead of 127/27. All neighbors to the site seem to be the same, with the addition of 161/01 on cch of 773.05625 which I can’t pick up from here in Dripping. I also ran Pro96com on the Austin site (101/01) - it’s still showing 127/27 as an adjacent site, but status is “failed, stale”. Austin site also showed 102/02 as “failed, stale”. I got similar results running site 114/14: 102/02, 127/27, and 150/50 (never seen before) are all showing “failed, stale” - with 151/01 as a neighbor and same cch as 127/27. 161/01 is also an adjacent site to 114/14. I don’t know how long it’s been that way - hadn’t turned on the G5 in a couple of weeks and it wouldn’t connect this morning. Oddly enough, APX doesn’t seem to care - it was still getting traffic.

Strange, but I did see a 160-60 as a neighbor of 102-02 a few weeks back. Couldn’t hear anything on the CC it reported at the time. They may be changing some things around on the 900 side as they begin to roll out P25 and retire OpenSky.

I'm seeing the same, Dripping Springs site 127 / 027 is now 151 / 001, everything else is the same. I punched in 773.05625 and that's showing to be the creedmoor site and it's RFSS / Sys ID has also changed from 102 / 002 to 161 / 001.

I can't wait for opensky to go away, the dripping springs site has at least 6 opensky frequencies, and they are all active control channels which seem to transmit constantly, which causes a ton of birdies or images on misc scanners around the house. maybe i'm wrong, and someone that knows more about the opensky stuff can chime in, but I sat under the tower about a year ago with no antenna and the attenuator on and i found several transmitting control channels in the 935-940 MHz range.

They aren’t all control channels. It’s like iDEN used to do and all channels at a site always transmit.

iDEN did have a release that introduced power reduction that would stop an unused channel from modulating, which with an 18.54 kHz wide signal saved a lot of power. They couldn’t stop it from transmitting as the ramp up time on the transmitters was too slow for that.

gotcha, i know they all transmit and it creates images of them as far down as the 2m ham band.

As of this morning, Dripping Springs is showing to be 150/50. More in line with their overall numbering scheme for RFSS/Site ID. Maybe this is where it will land…

Did it perhaps relocate from the Cedar Valley tower it has been at? I think that’s what LCRA officially calls it anyhow.

Today i noticed 2 new antennas and a microwave dish on the dripping springs lcra water tower which is a few miles west of the dripping springs lcra site. the antennas are similar to the p25 antennas on the actually dripping springs p25 and opensky site and it looks like the dish on the water tower is pointing at the dripping springs tower. the water tower is owned by lcra. maybe this is some sort of temp site while they transition the cedar valley tower from opensky to p25? i dont know if they are staying on 700, taking over the 900 opensky or both. hoping someone knows more.

Lol, as long as the frequencies and location haven’t changed, we will let them settle for good on a site number before we change anything. It won’t affect how the scanners operate anyhow. But they are obviously in some kind of expansion mode…

Yeah i have a hunch the water tower site may go active while they change things up at the old site 27 that they called cedar valley. when I can confirm what the new site is i'll let you know. Things may be moving a little slow due to all the trees down from the major ice storm we had. there are still over 110,000 without power.

Looks like Creedmoor shifted from 002/102 to 060/160

Dripping Springs still humming along on 050/150

Dripping springs site went dead for an hour, So i scanned and I just found the CC is now 772.03125, a freq that's not listed anywhere. i'll hook up Pro96com and post my findings. it may be just a new CC frequency and all the voice channels are the same.

It should be 772.03125, they updated the Dripping Springs site on license WREW251 and differentiated between two sites in Cedar Valley and in Dripping Springs proper.

I've been out of the loop for a while, so the antennas on the water tower I spotted is a new LCRA site!? woo hoo ! Where is it on the man LCRA page or has it not been updated yet? Those two locations are very very close together, I wonder if they are going to ditch the old dripping site? (previously called cedar valley). I've been listening to the SDS's this morning then they went silent about an hour ago.

From what i'm seeing, there's 2 new frequencies, one of them is the new CC and then the new site has a new voice channel of 772.85625. I may know why they put another site on a water tower just a few miles away, there's a pretty gnarly hill that blocks a lot of RF. It looks like there's only one CC (772.03125) and it's coming from the dripping springs site 150. maybe these two sites are linked and only identify with 1 control channel as site 150? I guess we'll learn more along the way. I think it just went active a few hours ago. My guess is the water tower physical location may be 701 E US-290 Dripping Springs, but the gate to access it is around the 1000 blk. There were no FCC ID signs on the gate and no physical address identified. There may be signs on the other gate right outside of the water tower itself but i'm not trespassing :)

Another screenshot, it keeps updating:

Being that you are the first to hear it on the air, the database is waiting on your submission to be updated good sir;)

Lol, just shoot us a sub when you have all the new channels verified, doubt the RFSS/Site or NAC changed.
