I need to encrypt some P-25 traffic on a XTS3000 and XTS5000. All I need to do is prevent scanner listeners (actually just one person) from listening. As far as I'm concerened, 4 bit cypher would be fine.

Does the software encryption option work on the XTS3000?

Does the XTS5000 even have software encryption option?

Assuming software encryption won't work, what is the cheapest way add encryption to these 2 radios? The encryption can have backdoors, and be weak as heck. I just need to knock out one scanner listener who is a Pain in the butt!!!
I have the XTS3000, and my friend has the XTS5000. My flash supports s/w encryption. I can't say what flash the XTS5000 is at this time, but it's stuffed with tons of options.

Any input would be greatly appreciated.

Your best bet would probably be Motorola's software encryption. I belive they call it Adavanced Digital Privacy. Its not a very robust form of encryption but for what you need it would probably be much cheaper than buying modules and keyloader.

If you went the DES-OFB route you could pick up an XTS3000 module and a XTS5000 module (which are different btw) for around $500 second hand or $700 each from Motorola. DX keyloaders are pretty affordable but I am not sure if they work with the XTS5k or if you need a KVL3000.

The software encryption in your 3000 is not ADP, it's the old software encryption from back in the VSELP days. I presume you have a whoreflash installed?

The UCM route is probably the right solution... if memory serves, a 3011DX will load an XTS5000 just fine (depending on the key management solution you're using, but it sounds like that doesn't matter for you).

Those prices for a UCM module a little high. A used module des ofb/xl will run about $150.00...

As far as a key loader I recently bought one for $250.00 with the right cable (used).

or find a friend with a key loader and set the radio for infinite key retention and load it.
