• 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 have several radios with the following model number HT71508U1X and features installed
1
4
7
8
9
10
23
I was curious to see if there was a way in RPM or programmer to edit the features and add in P25 conventional. If so what is the name of the software that can do this and what would be the protocol for changing this. If not and its a Harris only thing then thanks for the answer in advance.

No, features and feature strings have to be processed and downloaded from Harris. The P7100 is no longer supported.
What people have been doing is buying another P7100 that has all the features you are looking for (does not hve to be the same band model)
But should have the same or later firmware.
Then swapping the ESN chip and copying the encrypted feature string.
RPM works fine for the task after the chip swap and use Maintenance to edit the feature string.

This is exactly what folks i know did. They bought a useless UHF Low split (403-433) that had a nice loaded P25 trunked set and transplanted it into my VHF that was analog only. The soldering isnt bad if you have experience with board level repair and it was trivial to transplant the feature string. You can also transplant a P7100 into an M7100 to upgrade the super cheap 110w VHF mobiles floating around. Same chip, same process.

I'm going to try that on my APX MACE.
