Icom 2 Tone Detect Setup

[BlueDevil]

Our FD has several Icom mobile and portable radios. I would like to set up these radios to detect our tones (2 tone system).

It is my understanding that these radios are more than capabile of doing this however I cannot seem to get it functioning right.

Our department uses 4 different 2 tone combinations for different station dispatches. Can I stack all these on one channel so that the radio will be able to decode any of the 4 combinations? I would prefer that the radio didn't beep but just display text identifying which tone was being set off. Hopefully this make sense...

I have the tones and am familiar with navigating the programming software but just can't seem to make the radio do what I want.

Thanks,

Brandon

Brandon In order to due this, you need to setup a differant channel with the 2-tone and then a 'no' tone which will allow you to listen to the normal traffic and then say at night, turn to the 'tone' channel and it will 'open' on the tone.

Check your e-mail.

Ok that helps! For some reason I was under the impression that you could "stack" multiple 2 tone sets on one channel.

You again! (Snicker)

What version do you have? (see my other post.)

In the F50 V and MCD series, you can stack ten 2-tone decodes on a single memory channel. Just remember that with MDC radios in 'LMR (2-Tone)" mode the radio will stay muted until signalled, and Auto Reset timers can be programmed to re-mute after X seconds. The V versions have both "AND" and "OR" options. I normally program TX-inhibit which prevents accidental 'butt dialing'

I have the IC-F50 LMR and I am using software version 2.1

I cannot seem to get the radio to open up. I know I have the right tones programmed although I must not have the rest of the settings programmed correctly.

Thanks,

Brandon

Do you know the Tone A & Tone B?

 

[BlueDevil]

Sure do

 

[bravo14]

Sure do

cool deal.

I have programmed the radio with the Motorola A-B tones however the radio does not open up with the tones. I am assuming that their is some variation between the Motorola tones and Icom tones, enough that the Icom radio is not opening up.

Any suggestions or ideas?

 

[cabletech]

The Mot vs Icom is no problem as long as you have the current tone sequence and the current timing.

If either one of these are off then it will not work.

I have 30 Icoms in my area that I have set for fire tones and they work just fine.

So I have tried adjusting the tone hz just to rule it out with no success. I have also tried adjusting the group/individual settings along with the 1st/2nd decode. I just can't seem to get it to work properly. Does the TimerA or B have to be set to something special? We have a standard two tone system with Tone A being 1sec and Tone B being 3sec.

I know others have reported success, but I have had absolutely no luck getting Icoms to decode paging tones. They seem to be far too sensitive to any frequency error in the tones. I have tried changing every option related to tone decoding, including some in the "reserve" section of the software, all with no effect. The allowable frequency error seems to be hard coded into the radios firmware.

I have tried to get a F33G, a F3161, and a F5021 to decode my counties tones, and the best any of them will do is decode maybe one out of five pages, and the F5021 will not decode them at all. Meanwhile my Motorola and Kenwood radios have never failed to decode a page.

I am beginning to think there are too many fine tuning errors or inconsistencies in our simulcast system to make it work.

Thanks for the reply!!

I finally got one of the tones sets to activate. It appears that the tone values are off slightly. Now I have to figure out what the real tone values are to program into my radio.

 

[reconrider8]

How do you guys figure out the tones? Cause I wouldn't mind setting my radio up with that also

 

[BlueDevil]

I have been using Two Tone Detect for other services. It keeps a log of the tones received.

There is a free program called Audacity that will do this for you. I personally haven't used it much.

 

[reconrider8]

How exact is two tone detect? And does it log the high point of the tone like the actual page out tone?

 

[BlueDevil]

Anyone know what the tone tolerance for Icom radios?
