SDS100/SDS200: Monitoring The Professional Wireless Communications (PWC) Hytera XPT System

[JASII]

I am looking or suggestions on what other steps I should take to monitor the Professional Wireless Communications (PWC) Hytera XPT system. I have found the following frequencies of theirs to be active with Color Code 4.

452.1000

463.6500

463.8000

462.0750

462.7500

I have them programmed into my Uniden SDS100 as a MOTO TRBO system. I have a number of talkgroups programmed in and I am hearing a number of calls on various talkgroups. I also ahve ID SEARCH enabled.

My concern is the dreaded LCN issue. I have been using the LCN Finder feature and I have been getting different LCNs each time I run it. Does anybody here have any thoughts on what I can do to verify which LNCs are correct?

I have added a URL to the FCC website to show t=what the licensee is authorized for. I have also linked a previous thread on this tih similar concerns.

BCD436HP/BCD536HP: - Hytera Tier 3. Problem

Uniden 436HP in trunk mode can't find LCN. It only searches for Motorola systems. The problem has been known for a long time. Should we expect a fix? Why doesn't it work on Hayter's systems?

Use the LCN calculator to check what LCN you get that seem to be the most relevant.
If any of your frequencies belong to a different site then the scanners LCN Finder cannot properly figure out the correct LCN. You can only use frequencies you are certain that they belong to the same site.

Looking at th is a bit closer, it is possible that these three are in Minneapolis:

452.1000

463.6500

463.8000

This might be in Chaska:

462.075

And this might be in Newport:

462.375

If that is the case, then I gather that one site should have the first three frequencies. Another site would have just one frequency and the other site would have just one frequency.

If/when I do an LCN Finder on the sites, would the three frequency site likely have LCN 1, LCN 2 & LCN 3. Then, the single frequency sites would each show LCN 1?

They can set any LCN to any frequency and they can also send out data info about a new frequency and its LCN if they expand. If you only get those low LCN numbers then it is not a system that follows any bandplan but instead use programmed LCN numbers to its frequencies and slots.

You can usually see if frequencies belong to different sites by looking at their signal strengths in detail.

You do realize there's a database entry for this, correct?. The "Newport" 462.375 you brought up hasn't yet been documented in the RRDB. Examining WPMH825 I'm also seeing a site in Bloomington not in the RRDB at 463.200...

FCC ULS search queries time out after a certain amount of time so therefore this URL is now invalid. Always best to provide the URLs directly from the licenses and not a query

Yes, but the database entry is incomplete. I have never heard any activity on 463.200. It looks like Professional Wireless Communications (PWC) is licensed for more frequencies than they use.
