• 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.

I hope this is the correct forum to ask this...

When a 700/800 Mhz P25 system is installed, and they include simplex Portable to portable / car to car, etc. frequencies, are those reflected on their FCC license?

I have heard different areas advise to go to simplex before, but I don't know where to look to locate these freqs.

Would they be in the NIFOG? Throw a frequency in? Use one of the repeater / system freqs, to talkaround on, that are already recorded on FCC license?

These would be the class "MO"s

These would be reflected as Class "MO". This class also covers input frequencies however

What system is it? We need to know that and the location first. Anything else will be speculation.

There could already be a list of simplex frequencies in the db or wiki.
An end user could license their own simplex frequencies or some could be provided by whoever operates the system.
There could be 700 MHz State License frequencies that don't require a separate license for each user. You won't be able to find those easily. Some states list stuff like that in CAPRAD and some don't

Public safety licensees can operate mobiles and portables on some of the national interoperability channels under license by rule that don't require a separate license. Those are already in the db on the nationwide page.

There are twelve 700 MHz frequencies designed as "low power", nine of which can be licensed locally, and three which can be licensed for nationwide itinerant use. Unlike the nationwide interop frequencies, they are not licensed by rule and are supposed to be licensed under an SG license, but many ignore that and program them anyway. Those low power frequencies can also be used in narrowband analog mode, one of the few exceptions in the 700 band, which is almost exclusively digital (the Air to Ground frequencies being another exception).

You can find these frequencies listed on the National Interoperability page of the RRDB.

In North Carolina here we use the state-wide VIPER 700/800 Trunked P25p1 system currently. Some Counties are assigned what's called "Direct" channels, including my County. We use these Direct channels for scene ops and traffic directing since that stuff only needs to be broadcasted at a scene and doesn't need to be broadcasted over the system tying up one of the Voice Channels. I would hate to cause a Police Officer's radio to "bonk" because I have tied up a Voice Channel at that time with "Okay, let the red pickup truck go now"... The Direct channels at least for NC VIPER are basically a mix of Analog and Digital NIFOG 700/800 interoperability simplex channels already dedicated for Public Safety use but with different CTCSS/NAC codes for each County. So this way we can still direct traffic or communicate inside a structure and not have to tie up a Trunking Voice Channel and busy the system. Unfortunately not every County or agency uses these Direct channels. Some still prefer to use the Tactical channels that are broadcast over the system and uses up a Voice Channel...

We have that in our county on Friday nights after football games and fortunately at some churches on Sunday after services are over.
I wonder how long before some anti religious group finds out and complains.

One day in San Diego 2 units were doing traffic breaks around a crash that forced traffic to one lane. One unit said
"A range rover, the official vehicle of (community name), is the last vehicle"
The other unit said "Allow me to sweep the roadway first!"
