GENERAL
RECOMMENDED ACCESSORIES
FV-901DM
FV-901DM SYNTHESIZED, SCANNING
REMOTE VFO
The FV-901DM external VFO provides a PLL-
synthesized control system for your FT-901DM
station. A three-speed scanner will take you
anywhere in the band instantly, and the auto-
scan feature will sweep the band until it finds a
signal, then it will halt.
PLL synthesis in 100 Hz steps is coupled to a 40-
frequency memory bank, allowing wide versatility
for contest, DX, or net operation. The TX/RX
clarifier allows offset from either dial or memory
frequencies, for precise tuning.
For the CW operator, the use of the FV-901DM,
along with the FT-901DM audio peak filter,
means that one step of the synthesizer will
eliminate a signal from the passband.

FTV-901R
FTV-901R VHF/UHF TRANSVERTER
In another Yaesu "'first', the FTV-901R brings
three bands in the UHF and VHF regions together
in one compact case. The basic FTV-901R comes
equipped for 144—148 MHz, and the 6 meter and
70 cm modules can be added as options.
The satellite 1—3 bands provide operation on
OSCAR Modes A/B/J, on full duplex, when an
external receiver is used. Of course, the FT-225RD
or FT-221R transceivers can also be used for
transmission on the OSCAR 145 MHz uplink.
In this case, your FT V-901R can be used for instant
QSY between 29 MHz, 145 MHz, and 435 MHz.
Repeater split is provided on 50 and 144 MHz.
This means that you can use the FM capability of
your FT-901DM to full advantage on these bands.
