• 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.

In a talk group, where CRKs (multi-key encrytion) is used, how many can I add?

Thanks for everyone that helped me out with my first thread. THANK YOU :)

I'm programing up some handhelds and the customer asked, " How many CKs can each radio manage?"

I'm assuming the want to know when multi-key encryption is used, how many can be used in a talk group.

Any suggestions? I've looked all over for two hours now...

Without knowing what type of radio you're talking about there's no real easy way to answer your question.

Somewhere other than home :(
And it's CKR (Common Key Reference). :wink:

If you're talking APX7000 I believe it's 128, whereas a XTS5000 is 48.

So yes, more info would be needed.
