The Radio Information Board

I need help. I don't know enough about the tk 730g. I bought one and installed in my personal vehicle (I am a reserve Police Officer) and assumed it had scramble like my Kenwood handheld. Evidentally it needs a voice scramble board. Does anyone know where I could get one or an after-market product that will work. We do a lot of drug interdiction and I need it very badly but have search to no avail. I can't even find info on the subject. Any info would be greatly appreciated.
Thanks,
j

There are many different types of "scramble." You'd have to find out which one you are using to see if that radio can function in that manner.
