2 Tone over P25 Conventional

[KX4KDH]

Since firmware v1.2, the ability to be paged over P25 conventional has become available. I have a county that uses 2 tone over P25 to trigger APX base stations at each fire/rescue station as part of an alerting system. It works great. However, I can't seem to figure out how to make this happen on the G5 pagers. I have the tone sequences in the P25C sub-group ID sections. So far, I have not had any alerts when a page goes out. For that matter, I can't get the G5 to NOT pass traffic in select call mode.

Does anyone else have a city/county that uses P25 conventional, or am I the only one?

When you set up the zone did you enable under knob talk group list sub group setting ? and put the tones in TG group ?

In the select call mode it will not pass voice unless the tone pair is received

I did all of the above. At least I’m quite sure I did. However, I am sure I got lost on something somewhere. I contacted David about this, and I think I’ll have it whipped in the morning.

Please share your results, I have had issues with this if this is currituck county, many of the tone pairs are similar

I absolutely will.

One thing that I have noticed on many P25 paging attempts is that the tone level is too high and the tones get distorted or actually cut off.

You might try to lower the paging audio level to see if that helps. Try to listen to the voice channel being paged out on and see what is going on with the tones with a good radio.
