• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Google Data center in Pryor OK

Google has a massive data center just south of Pryor, OK that is licensed for quite a number of frequencies - WQIR860.
It is a monster facility and it is growing even larger. I was heading to Tulsa this weekend from Joplin, so I took a bit of a detour for a few hours Friday and Saturday.
On Friday, just about all the frequencies were busy. Looks to be 2 linked DMR sites, one with Color Code 4 another with CC 7. I brought 3 TRX receivers, and several times I heard the same comms on 2 different frequencies, which turned out to be one on each color code, and thus on each site. No LCN info as Whistler does not have that as Uniden does. :(

Five of the 23 licensed frequencies NOT in use in this short period, and one more frequency being used in the system that is NOT on their license.
Seven Talkgroups were in found use, 6 of them in the 779#### series, and one more as long, beginning with a 6. The TGs were seen on both repeaters with the 2 color codes, and each TG was either a slot 1 or 2.
Several TGs were various security types, one with over 40 RIDs/UIDs, tho the numbering scheme of the RIDs makes one think there are over 500 radios. Other TGs were shuttles, and general operations. Nothing very exciting or “Googlish” – there were no chats about RAM or hard drives etc. ☹

I have attached my spreadsheetin Pdf form with all the TGs and RIDs because I can't figure how to make a table in the forum, not post the underlying spreadsheet! If anyone has anything to add let me know before I submit.
(GooPry# means Google at Pryor with a number from 1-23 of the licensed frequencies in ascending order)

I just drove by and this appears to be all conventional and not trunked. There is no control channel or rest channel.

Based on hearing traffic on multiple channels at once I’d say they are utilizing some sort of IP Site Connect.

Hmmm, some TGs appear on several frequencies - see my "spreadsheet" - I'd think that makes it trunked!

Then there must be missing frequencies, because none of the ones on the license showed CON or CAP+ control / rest channel.

Being such a small area I wouldn't think that they would need IP Site Connect, but that is possibly why it would be on multiple frequencies. IPSC isn't trunked, just connected repeaters.

Help me understand - if IPSC isn't trunked, can the same TG appear on 2 or 3 frequencies?
In fact, MOST of the TGs stayed mainly on just one freq, but the busier TGs were on 3 or up to 7 freqs.

Google has so much bandwidth that it may be a nationwide system with RF at each of their sites. They are so interconnected for their business that it wouldn't surprise me if all the worker bees were working as a single hive.
