AOR's digital voice technology delivers audio quality you have to hear to believe. Whether you are working digital voice across state lines or across an ocean, amazing doesn't seem strong enough to describe it. With an ARD9000MK2, it's easy to convert existing HF analog transceivers to work digital voice with NO transceiver modifications.
