• 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.

do encrypted radio systems for states and municipalities lose the encryption key and revert to in the clear or does this only happen to federal systems? thanks

Depends.
a. Make/Model
b. How the keys are programmed/stored (and how the keys get reset/lost)
c. IS the channel STRAPPED for ENC or selectable
d. Too many variables
e. Is it a Cache radio that might only have some keys
f. Mutual Aid Radio - aka neighboring town
d. Too many variables

. It does happen on occasion. My local pd has a couple squads that transmit in the clear most of the time, but I don't think they realize it. They probably are so used to hearing the beep, indicating encrypt that they don't notice when its not there. I like it when their radios lose the key. :). 73, n9zas

The encryption sends out a carrier with no modulation on your scanner...you will see the channel come up but thats it! You can buy a motorola that will hear the encryption but all kind of letters must be given to the radio programer even though its on receive only! A person can buy one at one shop with receive only and go to another shop and have it changed!

Dont they have to also pay for the lease of the Encryption ........

I work in a municipal radio shop. There is no "leasing" of encryption. The individual agencies are responsible for the costs of using encryption. A local city PD uses DES encryption in 50 of their XTS 5000s for Special Ops/SWAT. They are responsible for keeping up with the radios and encryption modules and they stop by our shop if they need to be re-keyed or if the encryption modules need to be moved from one radio to another.

I live a couple miles away from a military facility. Everything except housekeeping, maintenance and Range Control is ENC. But, sometimes they slip up and turn off the big E. I like it when they slip up. LOL. I have a couple dozen TGID's that are NOT in the Radio Reference database. But with enough listening I have been able to label them. Not sure if I should submit them or not..

Why don't they do over the air re-keying?

Over the air rekeying is not as common as people think. Part of keeping track of radios for a larger organization is to put physical hands on it once in a while. This could be to change programming, rekey comsec, swap batteries, hook the radio up to test equipment for periodic maintenance and so forth.

One group I dealth with, all Motorola radios were touched for re-keys. All Harris PRC-152's were done over the air. Anybody not re-keyed had to come to me if they missed that re-key. There were reasons for both of these situations.

Many years back I was in Miami for a work project and was carrying a Motorola Systems Saber (ham GMRS stuff). I was dressed business casual and walking from my car into the hotel right by the Miami Intl Airport. As I approached I noticed a bunch of federal looking guys in suits and a table set up right inside by the side door with radios and keyloaders. One of them approached me and actually asked if I "needed my radio rekeyed". I told, him "no thanks" I am all set! I wonder what would have happened if I had let them go ahead load a key!

That would have been freaking awesome if you actually pulled it off. If your radio is equipped with the same flavor module they are using and the same band split, you could have later entered their frequency and, well....

It would also have been incredibly careless if they had key loaded your radio and what could they do to you if they did and found out later?

Who would be affected ? Monitors or users ?

Monitors ? Who cares, not the problem of the system owner/operators :roll:
Users ? Yup, they are told bring in the radio or directed to do xyz and press abc and wait for QRM... done
So affected parties can prepare.

It's not uncommon for agencies to announce such plans.
