Fire Tones

Does anyone know the Fire-Tones for West Douglas County FPD & the I-70 Corridor Departments that South Metro Dispatch for?

From the wiki:
Douglas County Fire Tone Out
Not sure about the others, but you can use Audacity to figure it out if the tones are single frequency for each one in the sequence. I don't remember the exact steps but once you recorded the tones, you highlight each tone and Analyze -> Plot Spectrum. A window will pop up with a plot of the spectrum and there will be a spike for your selected tone. Hover your mouse over the spike and the frequency will be displayed in the Peak field. I did that for all the Boulder County tones before adding them into the wiki (years ago).

edited to correct the Audacity sequence.

I Should be able to figure that out for the I-70 Departments, but I’m not close enough to listen to WDCFPD, and their Talkgroup isn’t on any of the live feeds.

I had time and analyzed all the tones just now on the P25 side. I can add these to the appropriate county wikis when I have some time and do some double checking.

West Douglas Long (Digital): 344.25 Hz
West Douglas Two-Tone (Digital): 1470.5 Hz, 1128.75 Hz
Note: I only have digital recordings and do not know if they are the same for analog VHF because P25 shenanigans rounds the tones to certain frequencies. I think that there is a good chance that they are using Quik-Call II tones, which would mean that the analog long tone is 349.0 Hz and the analog two-tone is 1472.9 Hz and 1122.5 Hz. This needs to be verified.

Bennett: 598 Hz, 752.5 Hz
Byers: 344.25 Hz, 435.25 Hz
Deer Trail: 598 Hz, 789.75 Hz
Sable Altura: 407.5 Hz, 344.25 Hz
Strasburg: 598 Hz, 719 Hz

Please feel free to add that to our wiki. This is where all Fire Tone data is kept as the database can't handle it
