• 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.

Anyone know much about the voice privacy and enhanced voice privacy on Motorola XPR 7550e DMR radios?We use them at the location I work security at,just wondering how secure the voice privacy protocol is,and if it sounds similar to the DES/AES type encryption Motorola uses on it's high end radios.

The voice quality is diminished slightly when using privacy as it uses some of the error correcting bits in the digital signal for the sync. I would not call it unbreakable but will keep the scanner user at bay,

Basic Privacy has 255 total codes. Takes about 3-5 hours with CPS to try all the codes. Advanced Privacy is relatively secure from casual listening (several million codes), but is allegedly simple to crack (on paper at least). There are rumors of a software in the wild that will recover the basic and advanced keys over the air, but I have not confirmed its existence. What amount of time are you hoping to protect the communications from being recovered? Asked a different way, how much time from the actual transmission to someone else recovering the traffic would you be sensitive to? Basic Privacy protects you for a few hours, Advanced Privacy protects you for days/weeks, AES protects you for millions of years (allegedly). TT

I really don't think anyone would be interested in our security traffic here at the Facebook data center lol..sounds like it would provide security from any casual listeners....

Nice. I was involved with an on again/off again project with those folks (I am a field tech for a large radio manufacturer). We see most customers use it to prevent their comms from being retransmitted on the news during/after big events. TT

There is a 'guy' in Russia that has made a single board radio receiver with custom firmware that can decrypt Trbo on the fly. He produced them for a time but suddenly pulled them from the market.
