Kenwood Encryption?

[SCPD]

My local park rangers use an analog conventional radio system in the 151.xxxx VHF range... the channel known as "Secure" or sometimes they call it "Channel 2" sounds kind of like aliens talking. It is a repeated channel, both radio channels use a DPL of 023. (This is not in the database so...)

But sometimes it hard to tell because the repeater doesnt have the open air time that some repeaters do. (I mean after they click the button the repeater goes off, it also sounds the same on their input frequency when they are talking over the repeater no air open time after the TX) I hope this is making sense.

I can confirm they use the TK-2302VK for their portable radios. Not sure on the car radios, the reason they wanted to buy the new portables in the first place was because the car radios were starting to break....and they don't have the money to "go digital". I know this because I was at the town meeting when the bid was happening. Anyways, they said they bought no extra hardware to encrypt their transmissions... so any help in finding out what kind of encryption would be "standard" on a TK-2302VK Thanks!! would be very helpful! BTW I am using a Uniden BC72XLT to monitor... not sure if this matters or not.

Thanks!!

It is probably "voice inversion". "ch 2" is probably the same input and output frequencies but the voice inversion is enabled.

So, could I buy a radio like theirs and just program RX freq, the DPL tone and the voice intervention code they're using or would that be a no-no?

Yup, you could.

You could even try downloading the old invert.exe program for your computer. You feed it audio from your scanner and it normalizes the audio and plays it out the PC's speakers.

As for the legality of it, I don't have a clue. If you are successful, I'd keep it quiet and enjoy it.
