DTRS Silver Heights site

[dw2872]

I am noticing 3 new frequencies that have probably been there for a while and have just not been updated in the RR database ( Silver Heights (Denver Metro) Site Details (State of Colorado DTRS) ).

The frequencies not in the database but that show up as being used by the Silver Heights site are:

Channel / Frequency
00-0689 / 855.3125
00-0817 / 856.1125
00-1013 / 857.3375

One rare chan/freq that shows up on this site only when it is very busy is 00-0271/852.7000 and is already listed in the RR DB. Seen last on 6/9/2014 at 10:06, but others have probably seen it since then. This is one that is shared with the DRDC site using that Dynamic Frequency Blocking (DFB) that Chuck mentioned in another post.

Can anyone verify that these three new frequencies are in use and maybe post a new tower file? Thanks!

I can verify the 3 new frequencies. Silver Heights seems to have an abnormal way of how it uses frequencies as it doesn't seem to rotate frequencies, but uses them in order of channel priority as the three new frequencies only see limited amount of grants. I also believe that 00-0181 / 852.13750 is used with DFB in conjunction with the Franktown site.

Thanks! That is great info. I have been analyzing the way channels are used on a few other sites and see that there is definitely an order pattern of use after the others get busy. For instance, here is an example of what you might see on this site (you see this site more often than me so you would know better in this case, but it is only an example):

Channel / Frequency / Use
00-0047 / 851.3000 / ID info (CWID), 5th choice voice/data
00-0131 / 851.8250 / Common voice/data channel (choice 1-2)
00-0181 / 852.1375 / 10-11 choice Rarely used SHARED w/ 1-010 (Franktown)
00-0221 / 852.3875 / Common voice/data channel (choice 1-2)
00-0271 / 852.7000 / 10-11 choice Rarely used SHARED w/ 1-009 (DRDC CF)
00-0307 / 852.9250 / Alt control channel, 3rd choice voice/data
00-0351 / 853.2000 / Alt control channel, 6th choice voice/data
00-0403 / 853.5250 / CONTROL CHANNEL
00-0463 / 853.9000 / Alt control channel, 4th choice voice/data
00-0689 / 855.3125 / 7th choice voice/data
00-0817 / 856.1125 / 9th choice voice/data
00-1013 / 857.3375 / 8th choice voice/data

DB update has been submitted for the 3 new freqs on the Silver Hts site.
