The DVS-2 is a digital voice recorder designed es-
pecially for SSB, AM, and FM operation with newer
model Yaesu transceivers having a special jack for
connection of the DVS-2 on the rear panel. It offers
two independent functions:
r Recording received signals for playback later in
the loudspeaker or headphone;
r Recording signals, using the microphone,for
playback over the air (during transmission).
Each mode uses its own memory, so both modes
can be used to retain data at the same time. Operating
details are provided with the DVS-2, but a summary is
Connect the DVS-2 cable to the DVS-2 jack on the
rear of the transceiver. You must also have a micro-
phone connected to the MIC jack on the front panel of
the transceiver to record your voice for transmissions.
