For those who purchase two way radios with the intent to keep their conversations private, encrypted radios are the way to go! Why? Well, because with voice encryption, you can be sure that the information passed from you to the other parties is only communicated in that capacity.
Eavesdroppers would not be able to move through the codes to get access to your data. However, with voice inversion scramblers on a lower-security system, this is possible. So, we would recommend that you set up a more secure hopping code and/or frequency domain voice scramblers for those intending to gain access to your information.
Regardless of the security that you place on these radios, the other party who the messages are intended for will not have any trouble hearing it loud and clear.
