FTV-1000 Operating Manual Page 2
POWER Switch
This is the main ON/OFF switch for the FTV-1000 .
When you turn the FTV-1000 on, the PA section of
the MARK-V FT-1000MP will be disabled automatically,
so your station won’t attempt to put out full power on
28 MHz at the same time you’re using the
FTV-1000 .
ATT Switch
This switch engages the receiver front-end attenu-
ator, which will reduce all signals and noise on the 50
MHz band by 12 dB. This switch should only be en-
gaged for local communications when signals are very
strong, as receiver sensitivity will be significantly re-
duced when the attenuator is in line.
IPO Switch
This I ntercept P oint O ptimization switch may be
used to optimize receiver front-end overload charac-
teristics, for strong-signal or noisy environments. Se-
lecting
IPO bypasses the front-end RF amplifier, and
feeds the received signals directly to the first mixer.
RF AMP Switch
Selects the desired receiver front-end preamplifier
configuration:
CLASS A Switch
This switch changes the final amplifier operating
mode to Class-A . When operating the final amplifier
in the Class-A mode, the maximum output power will
be reduced to approximately 50 watts. Operating SSB
in
Class-A yields an ultra-clean signal waveform.
BAND Switch
This switch selects the 50 MHz amateur band seg-
ment to be used. When this switch is set to the “ 50-52 ”
position, the FTV-1000 will operate in the segment 50
MHz ~ 52 MHz. When this switch is set to the “ 52-54 ”
position, the FTV-1000 will operate on 52 MHz ~ 54
MHz. In either case, frequency conversion to the range
28 ~ 30 MHz takes place, for compatibility with the
MARK-V FT-1000MP.
ANTENNA Switch
This switch selects either the NOR or ALT antenna
jack on the rear panel, and allows convenient antenna
switching.
