Site 01 LCN Order

Good morning everyone,

RR LCN # // Frequency // Notes
1 // 851.21250 // Voice Channel, picks up transmissions followed by 3 beeps
2 // 851.82500 // Voice Channel, picks up transmissions followed by 3 beeps
3 // 853.16250 // Voice Channel, picks up transmissions followed by 3 beeps
4 // 853.73750 // Monitored 3 minutes, static only
5 // 851.26250 // Monitored 3 minutes, static only
6 // 851.55000 // Voice Channel, picks up transmissions followed by 3 beeps
7 // 853.41250 // Voice Channel, picks up transmissions followed by 3 beeps
8 // 853.68750 // Voice Channel, picks up transmissions followed by 3 beeps

Straight from the FCC database search coming back to Brevard County license WNWQ632 at the Titusville location,
1141 DAY STREET
TITUSVILLE, FL BREVARD County 28-35-35.0 N, 080-49-01.0 W

here is the list of licensed 800 MHz frequencies assigned to this site as of today:
I've added notes regarding any changes, in parentheses.
NEW TITUSVILLE SITE LICENSED FREQUENCIES:
Frequency
000851.22500000 (not in old site 1 list)
000851.25000000 (not in old site 1 list)
000851.56250000 (not in old site 1 list)
000851.58750000 (not in old site 1 list)
000851.75000000 (not in old site 1 list)
000851.82500000 (channel 1 in old site 1 list)
000852.26250000 (channel 10 in old site 1 list)
000852.75000000 (not in old site 1 list)
000852.88750000 (not in old site 1 list)
000853.16250000 (channel 3 in old site 1 list)
000853.35000000 (not in old site 1 list)
000853.41250000 (channel 7 in old site 1 list)
000853.68750000 (channel 8 in old site 1 list)
000853.90000000 (not in old site 1 list)

Compare this list to the previous list for Titusville:
(Note, the delete comments are based on the lack of any active license for that frequency at that site. If radio traffic is still being heard
on that specific frequency without an active license, then somebody has screwed up.)

01 851.21250c (still active)
02 851.82500 (Delete, license expired)
03 853.16250 (still active)
04 853.73750 (Delete, license expired)
05 851.26250 (Delete, license expired)
06 851.55000 (Delete, license expired)
07 853.41250 (still active)
08 853.68750 (still active)
09 851.76250 (Delete, license expired)
10 852.26250 (still active)
11 852.76250 (Delete, license expired)
12 853.51250 (Delete, license expired)

It seems unlikely that any unlicensed frequencies would be active, but as of this time, some of the old frequencies whch are not included in the current active license are apparently still carrying voice traffic. Interesting.

Both Sharpes and Scottsmoor voting sites (simulcast) are now active. The change was made to the Titusville site # and LCN order has changed. This just confirmed.

I wonder if they'd just GIVE us the new site logical channel data?

I would expect the answer to be NO but...who knows for sure?

How do you know that the new voting sites are active?

If you are able to do so, please give the new Titusville site number.

the site number and LCN were not provided because they did not have that info on hand. I was advised the 2 most north voting sites are active currently.

I've been monitoring the frequencies from the new list above and Titusville is now transmitting analog voice on 9 of the frequencies. Four of them are part of the old frequencies (old LCN 2,3,7 and 8).
None of the other old LCN frequencies seem to be transmitting any longer.
The CC frequency has not changed. Listening in trunk mode I can see talk groups come up and the radio usually goes to one of the old unused frequencies momentarily but there is no signal. Very rarely it will go to one of the four old frequencies still in use and I hear the transmission.

000851.22500000 Voice
000851.25000000 Nothing
000851.56250000 Voice
000851.58750000 Nothing
000851.75000000 Voice
000851.82500000 Voice (old LCN 2)
000852.26250000 CC
000852.75000000 Voice
000852.88750000 Nothing
000853.16250000 Voice (old LCN 3)
000853.35000000 Voice
000853.41250000 Voice (old LCN 7)
000853.68750000 Voice (old LCN 8)
000853.90000000 Nothing

Here is what I have from trying to figure out the new frequencies and order:

1) 851.2250
2) 851.5625
3) 851.7500
4) 852.2625
5) -
6) 853.3500
7) 853.6875
8) -
9) -
10) 851.8250
11) 852.7500
12) 853.1625
13) 853.4125
14) -

I haven't seen anything on LCN 5,8,9, or 14 and I've monitored the following assigned frequencies with no traffic:

851.5875
851.2500
853.9000
852.8875

My PSR-500 says that it is site 12 but I am not 100% sure if I'm reading the analyze function correctly.

These assignments seem to be working but may not completely accurate.

Try simultaneously monitoring something busy (BCSO!) on two scanners, one set to Tvil and one to Rockledge. Since it may be presumed that Rockledge data is still correct, you'll know any time that the Tvil scanner misses a call or jumps to the wrong channel.


There is absolutely no guarantee that there aren't some expansion frequencies in that 14 frequency licensed list, which aren't currently in service. It may be quite possible that only 10 channels are currently active.

These frequencies match the new site called Cocoa in the RR database for Brevard County EDACS. I don't think the LCN is correct and it doesn't match what is in the post above.

I programmed it as listed in the RR database and only hear a few of the talkgroups.

If I monitor one of the frequencies as a conventional signal I hear transmissions that the trunk system does not.
I also see the site ID as 12 with a BCD396XT.

I checked it with SCAT dispatch on what are new Tville frequencies vs Rockledge; it is working on both the scanners I have programmed and I'm not missing any conversations. I would notice if the scanner tried to use one of the blank channels (they aren't empty, so I would get static like before with the wrong LCN and frequencies).

I reprogrammed the LCN as in post 5 above and seem to be hearing everything.
In ID Search mode I notice that Rockledge and Cocoa cities TG's are on this site?

Please post your version of the new list as it is programmed in your scanners and working as you described.

It would be best to submit your findings as completely as possible.

Please remember to include site ID numbers.

I am using the LCN from post #72. The 336XT shows a site ID of 12.

1) 851.2250
2) 851.5625
3) 851.7500
4) 852.2625
5) -
6) 853.3500
7) 853.6875
8) -
9) -
10) 851.8250
11) 852.7500
12) 853.1625
13) 853.4125
14) -
I still wonder why these frequencies match what was posted for the Sharpes simulcast site if this is really the Titusville site.
Also why the Cocoa and Rockledge TG's are being broadcast on this site?

Remember, this whole upgrade is centered around SIMULCASTING. Simultaneous broadcasting.

The idea is that as a radio in the system moves from the coverage of one site to the next, it switches sites seamlessly with no intervention on the part of the operator.

I'm not exactly sure how that's implemented in the radio side programming, but simulcating does apparently make use of duplicated frequency assignments in multiple locations.

Honestly I'm not as "up" on simulcasting in an EDACS environment as I'd like to be. Same applies to P25. But I sense learning taking place.
