Trunk system sound

[Jason_wyler]

A trunking system is controlled by a computer. Information (data) is exchange between the system radios and the computer on a control channel, sometimes called a data channel. It sounds like a strong buzz. A large system can have up to 28 freqs., 4 of which may be used as control channels.

What I am wondering is does the Ottawa trunk system have this as I haven’t heard this on my scanner yet that buzz sound.

Why would you want to hear it?

Why would you want to hear it?

No reason I just thought it part of the system and I hear it on my hometown system

I just like hearing sounds on radios and trunk systems. There's no big reason, but I just think it sounds cool. I don’t know how to get it on mine, if someone can help me

Scanners that decode P25 mute the control channel noise for a reason as it serves no purpose to listen to it.

It's good to learn what various digital signals sound like. I can help identify unknown signals in the future.

That should have been "It can help identify unknown signals in the future."

Program all the frequencies as FM conventional and you should be able to hear the digital noise without the scanner decoding the audio.

One freq trunk ?

No. Not trunked.

No. Not trunked.

So set the modulation from NFN to FM

 

[nd5y]

Either FM or NFM should work. You want the scanner to ignore the control channel so it doesn't start trunk tracking and mute the audio. Depending on the scanner you might have to set it to search (not decode) PL/DCS and/or disable data skip to force it to ignore the control channel.

It’s bcd325p2 so how do I do this I need easy instructions I do it by hands

 

[nd5y]

I don't know how the BCD325 works. Try entering HOLD frequency HOLD.

can i use software to do this ??

 

[Jason_wyler]

the only thing about software it mess up my display screen that what i dont like about software
