MEMA Two Tone

[matt131]

I have heard MEMA testing a two tone page on their frequencies. Does anyone know the tones?

Thanks

Heard a two tone pager followed by a 5 tone page today on MEMA VHF

matt 131 - I think there is software that can decode those tones. So if you want to go to the effort, and if you can make a digital copy of the pager signal, then there is a means to identify the tones. It might not be totally accurate IIRC.

tone A 879.0
tone B 569.1

The above tone has been confirmed

MEMA VHF frequency

what mema vhf frequency u guys talking about they have many and is 800 one still.runing cross patch or no just wondering

 

[matt131]

This tone is used on all of their VHF radio channels. The 800mhz channels should be patched to their VHF system.

The VHF/UHF System is networked [patched] Statewide, only when needed have they patched into the 800 [Part-time/On-Demand]

it sounds like MEMA has made changes to their paging and alerting of stations. I heard them testing 2 sets of two tone alerts with Amesbury today. I know the first set is 879.0/569.1 Does anyone know the other set?

Thanks

It would appear that MEMA has stopped using two-tone alerts prior to warning announcements. I was curious if anyone knows why. Have they stopped using pagers?

They now seem to be using a single alert tone. I like to set tone-out for MEMA for any alerts, which is nice because it filters out the routine traffic.

The single tone can be used.
tone A 1004.1
tone B 0.0

I've tested this and it works.
I'm using tone-out a lot now for Boston Fire for box alarms and second alarms, as well as BEMS for priority jobs and BPD for citywide announcements. Works great if you only want the priority traffic.

what coding option in the minitor are you using? I can't get it to work in my minitor 6 pager. I am using tone 1004.4 which is what my uniden scanner decoded.

 

[matt131]

I am being told that MEMA will be going back to two tone paging beginning of 2015. Also, does any have tones for Boston EMS on 460.525mhz?

Matt:

I do not use a minitor, but instead the tone out function on my uniden scanner. It has a tone out decoder or "tone out search" which will open the squelch or any tone. If there is only a single tone, the second tone is set to 0.0. I use it for almost every agency for priority monitoring in Boston. Can't use it for trunked systems, obviously.

BEMS TAC 7 460.525 is DCS 131 I believe.
