• 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.

Can a P7100 be programmed to work on a Harris GPS simulcast system with multiple cells? From what I gathered the P7100 only lists C4FM for P25 modulation according to the data sheet.Harris Simulcast Systems seem to use WQSPK modulation.Later Harris radio models like P7200 and newer list both for P25 modulation.

Would it even be able to demodulate WQSPK?

It should be WCQPSK not WQSPK. Tried to edit but won't allow now.They apparently also offered EDACSIP GPS simulcast systems from what I saw on one of their brochures.



Seems the P7100 may not be able to properly receive on a P25 simulcast system after finding this if all it can demodulate is C4FM.


'Digital Simulcasting'

"To add to your list of acronyms, there is another type of modulation scheme that's used with some multi-site Project 25 systems. Linear Simulcast Modulation (LSM) is a trademarked term for a form of CQPSK that provides a way for receivers to properly handle multiple identical transmissions. It's just different enough that the regular C4FM processing doesn't work correctly."

I have several and they work just fine on RX. TX may be another story. Just make sure they Ref Osc is set to a known good source so its freq is accurate.

As long as it works on the RX side that's works for me.I was wondering if it was more of an issue trying to TX,but not concerned about that for my needs.
