• 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.

Etherstack P25: Transmitting All Peer Control Channels

Question for those who are far more educated than I am.

First Energy has an Etherstack P25 Phase I system on the air in New Jersey using QPSK modulation, with Motorola APX subscribers. One particular site was displaying a unique behavior on Unitrunker the night before last, with the peer list quickly flipping between control channels. That is, displaying all peers' control channels in rapid succession. It's been analyzed by the software's author and it isn't a bug. Furthermore, it appears to be the only site doing so.

Can those familiar with Etherstack systems possibly explain for educational purposes why this might happen? And if not a site error, the technical nuances of why it would be needed? Thanks!!
