Before you do that, we should probably make sure you are 100% clear on a few things:
- Buying the appropriate SCM is only part of what you need to run encryption. The module on its own will not decrypt encrypted radio traffic.
- You need to have the encryption keys loaded into the radio once you have the key. Before spending money on this, make 100% sure that you can legally have the encryption keys and you have someone that will load it into your radio with a Key Variable Loader device.
- Make sure you have the adapter cable to go between the KVL and the radio.
- You won't be able to 'guess' the keys.
- There are federal laws against accessing encrypted transmissions that are not being sent directly to you by the sender.
The encryption modules are expensive.
The non-FIPS 140-2 AES/DES module lists for $550.00
They are also a federally controlled item and you can't ship them outside the country (I know, you are in NY), but they will often require you signing paperwork agreeing to that.
If you've got all that covered and are willing to spend the money on it, you should be able to contact a Kenwood dealer and they can assist.
