• 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.

Has anyone successfully programmed a G5 for a P25 Conventional frequency? The software will not allow me to save such a vhf freq without specifying at least 1 talkgroup, which I don't have for a conventional frequency.

I'll try and test this, I have the ability to transmit on a P25 conventional frequency. I think what you will find is there actually is a talkgroup assigned even when transmitting on P25 conventional.

Ok, thanks. I am not transmitting, only receiving. I set the G5 programming to monitor mode, with the P25 conventional protocol, with NAC, but at the very bottom of that page in the software there is the talkgroup info which must be entered before the program will save the frequency. The frequency I'm trying to enter is one of the National Park System P25 VHF frequencies.

Or try turning monitor mode on, if that works for conventional channels. (monitor mode from the menu in the pager, not in the PPS).

And if that doesn't work, try adding the P25 talkgroup FFFF (65535), which may act as a wildcard. That might only be for trunking, though.

P25 conventional

I have programmed P25 conventional in the G5 and it decodes and receives great. I listen to the US Coast Guard P25 vhf channels. To program it to receive you just make the talk group the wildcard as noted earlier ( FFFF). This allows you to receive any communications on a specific p25 conventional frequency without a specific talkgroup.

Just some side info , Specifically the USCG uses only a digital P25 vhf frequency not a talk group to transmit on. They use the standard NAC 293.

Any number should work. I've used 1 for talkgroup for P25 conventional. Not sure if that's different thatn FFFF.

I have found that FFFF does NOT work on trunking system as a wilcard for TGID. However, it does work for the WACN. I've also found that if you program the RFSS and Site as FFFF, it will display the correct RFSS and Site in DEC format on the screen. I had a problem with Miami-Dade P25 system....the DB has the wrong Site ID, should be 1. Confirmed with Unitrunker. So this is a nice little feature on the fly.

How does one enter a NAC wildcard to decode all NACs on a P25 conventional freq? Instructions say to enter 0xF7E but that is not accepted by the SW.

I have confirmed that F7E serves as a NAC wildcard.

I'm thinking of purchasing a G5. David send me a copy of PPS to try out so I could learn before I buy. My area has P25 trunking systems and P25 convention frequencies. When entering conventional NFM frequencies I had no problems. When I tried entering an convention P25 frequency (not Trunking system) the PPS software ask for the NAC and a system talking group ID. The software screen doesn't format the NAC answer box correctly so after I enter the NAC it kind of disappears. After looking at it for awhile I think the NAC code I entered is there, but is partially hidden under the text prompt for the NAC number.

Today my question is what would I use for a talking group number? For example Rock Co (WI) Sheriff and Janesville (WI) PD each have there own P25 conventional (Single channel) frequencies. They both use a NAC of 540. Radio reference does not list a talk group ID for either of these since they are single frequencies and not a truncking system. What would I use for a Talk grouple number to keep PPS happy?

I called David at Unication this morning. He said to use FFFF at a talk group ID for P25 conventional single P25 frequency. Not a trunking system.

I am getting ready to program in some APCO P25 conventional frequencies, have there been any changes on this?
