Is it possible for a Uniden scanner to handle old school "scrambled" analogue transmissions?

I don't think any Uniden scanners can decode the single inversion (donald duck sounding) scrambling, if that is what you mean. I have an AOR8000 scanner with the single inversion descrambler chip that will do the job and I think the AOR8200 will do the same if you can buy one with the descrambler chip installed. Ramsey electronics sells a manual that you can build your own with readilly available parts except for one item which you can purchase on their website.

Correct.

it is illegal to sell or manufacture such a device in the U.S. See thread about software:

Voice Descrambler software

Does anyone know how to make the Voice Descrambler software decode Voice Inversion from a recorded file? I can't get it to work. I can post a .wav file that is all voice inversion if you need me to. I can also tell you what Hz the Voice Inversion is on the file too.

Voice inversion *might* be a gray area since it is technically just inverted modulation.

As was mentioned, other manufacturers had VI boards.

Decryption is definitely illegal without authorization.
