HK-2217, Secure Voice Unit

 In 2004, a client from Italy wanted us to make a voice encryption unit able to be inserted into a Motorola GP300 radio.
The market already has some manufacturers in the same area (ex: Midian) but the price was too high and the client doesn't want that level of protection.
Therefore, we research the possible solutions and we come to a CML circuit and a PIC16F MCU.
The result was a simple voice inversion but with a intelligent variable algoritm secure enough for our client's demandings.

The PTA (Project Allocated Time) was 3 weeks from the first contact to the delivery of the final report among with the samples.
