Virginia fire dept tone-outs (bc396t)

[kg4rgn]

Has anyone started to collect fire tone-outs. So far have found one in my area; James City Co initial tone out for the fire dept = 1006.9 hz for 154.355. I will add more as a find them.

Here is the list that I have for SEVA. Some of the toneouts are not defined as I am not sure of their actual station or equipment use - I grabbed them from the location's daily pager test. Any help filling in the blanks would be appreciated.

I have given a couple of these to the admin board already (Hampton and IOW). I was going to send more but wanted to wait until I filled in some of the blanks.

newbie

i'm new to this what are the tones for and would i use these on my scanners somehow i have a pro-96 and a pro-97

These are the tone frequencies used by various fire departments to alert the pagers of their volunteers, or stations. The newer Uniden scanners (330, 396, and the upcoming 996) have receive tone pager ability. The RS scanners do not have this feature, so these will not be of much use to you at the present time.

Randy, thanks for the list. One question, the prealert 1004.0, does not match any freq found on any charts. Is this 1006.9, or as long as you are programs close to the freq, it should work with the BC396T.

thanks

Tone-outs for some areas are in the database. Loudoun County is posted here:

I think you will also find some in the forum archives as I recall some being posted when the new tone-out scanners were first released.

pre-alert

the 1004.0 Hz and 1006.9 Hz tone you're refering to may be the "Alert-1" tone on the console, which is 1000.0 Hz. if you're decoding the tone, it may not show exactly 1000 Hz.

tone-out for VA

OK, I will try and input 1000.0 into the scanner and see if it will still activate York Co and Williamsburg. I know 1006.9 works for James City Co and have not gotten anything else to work for the pre-alert.

Thanks

1004

the 1004.0 Hz and 1006.9 Hz tone you're refering to may be the "Alert-1" tone on the console, which is 1000.0 Hz. if you're decoding the tone, it may not show exactly 1000 Hz.

One bit of info--- in the Telco world when you test with a "1k" tone at a reference level, the standard tone generated by the test equipment is actually 1004Hz. I probably used to know why, but that brain cell died long ago.

i don't know if this matters with the scanners, but our radios must receive that pre-alert tone for atleast 5 seconds before it activates

1004.0 did not work for York CO, however 1000.0 does, go figure! 1006.9 and 1000.0 works for James City CO. 1000.0 works for Williamsburg,

Yes, topcop1833 you're exactly right. the tone is manually transmitted. kinda like the horn in your automobile. it only sounds as long as the telecommunicator is pressing the button, which can vary each time it is used.

 

[topcop1833]

i was refering to the time that the radio "senced" the tone. the radio does not activate untill it hears the tone for about 5 seconds. i guess it is so if the button gets pressed by accident or the 1000 hz tone is somehow produced it won't activate the radio until it hears it for a few seconds.
