• 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.

So, me and a friend of mine have NX700-E (since we are in Europe) in our hands. Both radios work well on analog and digital but just for fun we wanted to try digital scrambler. Connected both radios to program such channel but scrambler option is grayed out. Scrambler option is visible in the radio menu as well but it cannot be turned of - when you set it to ON and confirm, it automatically goes back to OFF. I thought that 15-bit digital scrambler is available by default. Is there something we are missing?

Did you set your code(s) in the encryption list?
Then go to channel edit and set the encryption table number?

OMG, poor me! Well, obviously I did not :) I was thinking that there is some predefined keys. So It's a lot like Hytera which I'm more familiar with.
Huge thanks! :)

Edit: Hmmm, maybe I'm missing again something - now I'm able to activate scrambler only on analog channels. We wanted to test it over NXDN

Sorry for double post but can't edit my post again.
So, I think I got it - when it comes to analog is under scrambler settings, but when it comes to digital channel you have to check encryption under encryption settings. Do I got it right? (my friend left and can't test my observations) :)

Right.
"Scrambler" is usually indicating some sort of voice inversion scrambler used in analog communications. It's not very secure and isn't too difficult to defeat.

"Encryption" is usually indicating digital communications.

The NX series radios do 'scrambling' only on analog and 'encryption' only on digital.

THIS....

Since transitioning to public safety communications, I'm frequently appalled by how often these terms are confused and misrepresented.

As someone who employed encrypted radio-communications for 20 years in the military, to hear anyone confuse voice-inversion for encryption, it makes my blood boil. This is especially true when it comes to officer-safety.

Are you concerned because the inversion has voice quality issues, or do you think Encryption is necessary for "officer safety"?

I believe that an officer mistakenly believing that voice inversion is true encryption could lead to an officer-safety issue.

Another thread there was talk of the AOR non us version being able to actively decode basic kenwood encryption and inversion. Just heads up since op saod hes in Europe.

The US version will decode Kenwood encryption as well if you read the thread.
