• 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.

Hello,
If this is not the correct section, I apologize. I have posted in a state specific thread but figured I would get more help here. (https://forums.radioreference.com/texas-radio-discussion-forum/354069-san-angelo-new-p25-system.html) Post 24.
The city I live in recently turned on an 800mhz P25 Phase 2 system for testing that will eventually replace the current EDACS system. I'm not 100% positive on the set up but I do know at least one site is simulcast. I was hearing it fine with no issue for about the first 3 days but now the signal keeps fluctuating from all the way up to completely nothing. Every so often I will pick up the System ID, Site ID, WACN, & NAC with the analyze fuction. (Using a BCD436HP).
I am within less than 4 miles of all 3 sites. I have no luck picking up site 1 with the frequencies listed in this FCC license (ULS License - PubSafty/SpecEmer/PubSaftyNtlPlan,806-817/851-862MHz,Trunked License - WQZJ592 - San Angelo, City Of) however, When analyzing site 2 and site 3 I am able to pick up the System ID, Site ID, WACN, & NAC (Both displaying the same information). Site 2 is 4 frequencies starting with 854.9625. Site 3 is 8 frequencies, Starting with the same 4 frequencies as site 2, followed by the 4 frequencies from site 1. When I listen to 854.9625 It is definitely a control channel.
I know there are issues with monitoring P25 Phase 2 simulcast systems but I don't know a lot about it. My only thinking at this point is to buy a Yagi and point it at site 2 or site 3. I have also tried turning on the attenuation for "Site 4" that I created with only 854.9625 listed but all it does is just lower the signal, Making the signal just from 1 bar back to none.

Yup, wrong forum and you've already got a thread open on this subject.

Please ask to have your existing thread moved and will be happy to put it in the correct forum for you.
