Comcast Center/Comcast Tech Center?

[kh11]

Anyone have any luck with Comcast's sites in the city? I loaded their info from the database in my SDS100 and heard nothing all day even though I'm line of site to them, about two blocks away. LCN search only pulled up 1 hit per site. The security folks in the Center always seem to have at least some chatter on their XPR HTs when I am passing through.

"Security" service type turned on?

"Security" service type turned on?

Yup. I also did an LCN scan on the Roxborough site again today. 1 of 3 found, no traffic.

I received this info from a source of mine. Try plugging in the following. LMK if any luck

WQTT559
Site 1 CC1:
Ch 1-2, LCN 1 461.4000
Ch 3-4, LCN 2 461.6000
Ch 5-6, LCN 3 461.9250
Ch 7-8 LCN 4 462.1125 (questionable, not on the license. Freq and CC match UPenn)
Ch 9-10 LCN 5 463.2000
Ch 11-12 LCN 6 463.3375 (questionable, not on the license)

Site 2 CC1
Ch 1-2, LCN 1 463.5125
Ch 3-4, LCN 2 463.6500
Ch 5-6, LCN 3 463.8500 (questionable, not on the license)
Ch 7-8, LCN 4 464.3375

So I spent some more time on it. Looks like only 461.400 is beaconing as Site 1, Chs 1&2, CC1

The rest of the frequencies, although at the same fixed base report they are Site 2, CC1

FCC Callsign WQTT559 (Comcast Corporation)

461.6000: 1&2
463.6500: 3&4
461.9250: 5&6
464.3375: 7&8

Traffic was rather sparse on a Friday afternoon but TG-103 appears to be the primary security talkgroup, didn't hear any activity on the TG-106 which might be a secondary security talkgroup, I have heard radio checks here in the past, though not today
TG-125 might be engineering. One hit on TG-123 talked about buses pulling up & guest reservations

Now TG-123 is sounding like another security frequency. Loading dock secure as is the bar on level 60?

Update, what I confirmed online as of Friday:

Site 1, CC1, WQTT559:
Ch 1&2, LCN 1 461.4000
Ch 3&4, LCN 2 461.6000

Site 2, CC1, WQTT559 & WQJV551
Ch 1&2, LCN 1 463.5125
Ch 3&4, LCN 2 463.6500
Ch 5&6, LCN 3 463.8500
Ch 7&8, LCN 4 464.3375

Site 1 appears to only broadcast TGID 103: Comcast Center Security (1701 JFK Blvd) & TGID 110: Campus Emergency Channel
Site 2: TGID 123: Comcast Technology Center (1800 Arch) Security & TGID 125: unknown use, not very active during my monitoring. "Table pick up on 5?"
