By my calculations :cool: 3005/3006 (1502) should be 463.7625 and 6871/6872 (3435) should be 487.9250. This agrees with the results above, so I'd say it's a pretty solid bet.

Although, that makes LCN 1 (from site 16) seem pretty unlikely at 445.000. I have to wonder if this was an artifact, since I only recall seeing it once.

463.7625 - Apple Newark - WPWU822
487.9250 - City of Los Angeles (I'm guessing not!) Besides, 487 MHz would be an input in the bay area.

I was thinking that 463.7625 may have been at the HP Agilent site in Santa Clara. I thought that may be a good guess since Telepath is listed as a contact for the license. Unfortunately, no control channel monitored from any of the frequencies in this license:
FCC Callsign WPBC944 (AGILENT TECHNOLOGIES INC) (radioreference.com)

Now that you have me thinking outside of the county, I agree with you.

I've had a mixed history with monitoring Telepath systems. I think someone may have uploaded the information from a network map dump from the system without actually verifying the information. I felt like I was going on a snipe hunt, looking for sites that were in the database, but weren't actually on the air. It should have been easy to find, since these systems broadcast a control channel.

Anyway, glad you found that Newark frequency, and that would be a good bet to go for a listen.

I would bet that's an artifact. Considering the ranges of all the other LCNs on the system, this one is an outlier. 445.000 MHz is also in the HAM 70cm band and wouldn't be a valid frequency for the system.

Good point about the input. Maybe the 6000 LCNs are on a separate band plan after all (probably just a different base frequency, same step). Searching for it in the UHF T-band still seems very plausible though, and since T-band isn't allowed everywhere that also pretty much limits the site location to either the Bay Area or Los Angeles.

I thought Agilent was a reasonable guess too, but if you're not hearing any control channels in the local area, it might be close enough to be covered by the Apple Park/Vallco site. In that case, Newark would be the next best bet.

Sorry for the delay on my part with this project, I'm working on confirming the LCNs for the sites I can get from South Sacramento via an external antenna today. From a quick look at the spectrum using DSDPlus, Site 4 is on Sys 9 (TIII), and Sites 38 and 39 are on Sys 268 (Con+). I'll submit LCNs later today.
