I think there may be a problem with the Telepath Corporation system listed here:
https://www.radioreference.com/apps/db/?sid=7830
…it looks like Site 01 - Monument Peak and Site 02 - South Bay Area may be incorrectly assigned to Telepath. I have a very strong suspicion that these two systems are in fact owned and operated by Apple.
Let's start with what we can see from the database itself. Here is the detail for Site 1 Monument Peak:
https://www.radioreference.com/apps/db/?siteId=26985
The control channels are listed as:
461.925 (LCN 2 / Color Code 4)
461.500 (LCN 4 / CC 6)
I strongly suspect that 461.5 is Apple's system and not Telepath. So let's look there first. The detail from Monument Peak shows that the Site FCC licenses are:
https://www.radioreference.com/apps/db/?fccCallsign=WQUG687
This license shows as being owned by Telepath Corporation, and located in Alameda County. But if you look at the frequencies for this license, there is no entry for 461.500 control channel.
If you do an FCC frequency search for 461.5:
California Scanner Frequencies and Radio Frequency Reference
…you will find Telepath Corporation, but the license is:
WQQT906 (TELEPATH CORPORATION) FCC Callsign Details
I am not ready to make a submission for Apple, but I've been monitoring this license:
WQMI679 (APPLE COMPUTER INC) FCC Callsign Details
…and I can say that 461.500 and the other frequencies from this license come in 5x5 / full quieting at the Apple Campus in Cupertino. What I have so far:
461.500 (LCN 4 / CC 6)
463.775 (LCN 1/ CC 3)
461.925 (LCN 2/ CC 11)
462.025 (LCN 3 / CC 5)
461.750 (LCN 5 / CC 7)
464.700 (LCN 6 / CC8)
…which looks a lot like what is assigned (incorrectly?) to Telepath:
https://www.radioreference.com/apps/db/?siteId=26986
According to my SDS100, the system (and the one below) are Motorola Connect Plus (as is the TelePath) and the NetID is 10Ch.
There is a similar concern with Telepath Site 2:
https://www.radioreference.com/apps/db/?siteId=26986
The control channel is listed as 464.7875. There is no site license for this site.
Search for all FCC licenses for this frequency:
https://www.radioreference.com/apps/db/?freq=464.7875&action=sf&stid=6
…and there is no record of Telepath.
But the frequency is listed to Apple:
https://www.radioreference.com/apps/db/?fccCallsign=WPWU695
And I can confirm that the Apple TGIDs (incorrectly?) assigned to telepath are present on the apple system I am putting together. I have monitored Apple with my SDS100, using the stock antenna on both sites (Apple Park and Infinite Loop). So I have a pretty high confidence level from the traffic monitored and the observed signal strength that the overlapping configurations for Telepath and Apple indicate with high probability that the assignment to Telepath is incorrect.
I understand the anonymous nature of submitted data. But if someone else wants to check my work. Or if the original submitter of the Telepath sites wants to contact me via this thread or PM, I would appreciate getting this cleaned up.
And one final question. How do you go about determining that MotoTRBO sites in different states are part of the same system? What identifying information in the Telepath entry for Site 1 / Site 2 in the Bay area link it to sites in North Carolina and Texas?
Thanks!
