Just to let everyone know that Ron and everyone else that helped out with the lpe-200 radio that the support was wonderful and the good news about the radio is that I don't need that file Ron has been looking for.
Okay. He still needs the file because that file is going to tell your LPE-200 what it is allowed to do. If you don't have that file, then you won't be able to do any of the following:

Those are the FEATURES that the feature encryption file will enable depending on the actual file. The reason that it's encrypted is because M/A-Com doesn't want everybody and their mama upgrading their radios for free. Say you want to add Pro-Voice to a non-Pro-Voice LPE-200. You call M/A-Com and ask for Option 29. They ask you what your serial number, ESN and current options are and then they make a new Feature Encryption file and email it to you. You enter the new string of numbers into the radio via Radio Maintenance and viola, your radio will be able to listen to Pro-Voice.
The reason that your radio is not working is because you went into Radio Maintenance and edited that Feature Encryption string. Now your LPE-200 doesn't know what to do, because the feature string is wrong. You probably thought that it had something to do with voice encryption. It has NOTHING to do with voice encryption. Voice encryption keys are not stored on the radio. You have to have a key loader/key fill device and a cable to attach it to your LPE-200. The key is stored in the KVL and "loaded" from the KVL to the radio. Once this happens, the radio will TX/RX encryption(DES, AEGIS, etc). You have to have the right key and the right version of encryption (DES, AEGIS, etc) though or the radios won't be able to talk to each other.
