FV-107 EXTERNAL VFO
FTV-107R VHFIUHF TRANSVERTER
The FV-l07 is a solid state remote VFO for the
FT-107M senes of HF transceivers. Featuring a
precision'analog dia1 coupled to a high quality gear
mechanism, the FV-107 includes clanfiers for the
transmit, receive, or transceive frequency, allowing
offset of
i
2.5
kHz from the dia1 frequency.
As many as six crystal-controlled channels may be
installed, for fixed, channel operation (crystals
optional). Selection of VFO or crystal operation
is made by a convenient switch on the front panel
of the FV-107. All power required by the FV-107
is provided by the FT-107M transceiver.
The FVT-lO7R is an all-new transverter for the
FT-107M senes, capable of operation on the 50,
144, and 430 MHz bands. The basic unit comes
equipped with all control circuitry, and the
430 MHz and either the 50 MHz or 144 MHz unit
may be installed as options (in the USA, the
144 MHz unit is built in). Power input is 20 watts
DC
on all bands.
For satellite operators, three satellite bands are
provided, allowing full duplex operation through
the transverter, using an extemal receiver in
addition to the FT-107M. The operator may trans-
mit on 145 MHz while listening on
29
MHz or
435 MHz, o r transmit on 435 MHz while listening
on 145 MHz.
The FTV-I07R includes repeater split on all
repeater bands within its operating range, for
operation on the many SSB repeaters that are
emerging. Fully solid state, the FTV-107R includes
protection for the final amplifier transistors against
damage caused by high SWR. Spunous radiation is
at least 6 0 dB down.
