• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

G5 QCII/2 Tone Paging over P25

Good afternoon,

I am fairly experienced when it comes to the G5 pagers as I have spent a lot of time around the PPS. The only thing that bugs me is the protocol parameter settings in the PPS.

To start- what I have works as it is but I feel like I would be more comfortable programming these things if I had better knowledge of how this part works. The attachment shows what I currently have setup in the PPS for a simulcast VHF system.

The parameters the county uses are:
Tone A: 1250ms
Tone B: 3000ms
Long Tone: 8000ms
Gap between two-tone pairs: 1500 ms

Before you say it I know some of these don't match up to the programming exactly and the reason I haven't touched it is because this is what the settings were on the pager when I recieved it and it works so I took the "if it ain't broke don't fix it" approach.

Obviously I don't want calls to be missed and really just want a little education on how this works. If there are minimum detect times like down at the bottom why would we need the settings at the top?

Thanks in advance.
