PERATION
You can operate the MARK-V FT-1000MP normally
when turn off the FTV-1000 . However, you must select
the transceiver’s ANT A/B switch to the position which
is connected to your HF antenna (either directly con-
nected to the
MARK-V FT-1000MP, or via the FTV-
1000 ’s NOR antenna jack).

Reception
1. Set the MARK-V FT-1000MP operating band to 28
MHz.
2. Disable the front-end RF preamplifier of the MARK-
V FT-1000MP (be sure the green IPO indicator is
illuminated), then check to be sure that the ATT se-
lector knob of the MARK-V FT-1000MP is set to
the “ 0 ” position.
3. Select the antenna jack “ NOR ” or “ ALT ” (whichever
is connected to your 50 MHz antenna, then select
the operating band. If you wish to operate on 50
MHz ~ 52 MHz, set the
BAND switch of the FTV-
1000 to the “ 50-52 ” position; if you wish to operate
on 52 MHz ~ 54 MHz, set the BAND switch of the
FTV-1000 to the “ 52-54 ” position.
4. Turn on the FTV-1000 , you will now be operating
on the 50 MHz band. The MARK-V FT-1000MP’s
frequency display will still be on 28 MHz; however,
you can use the transceiver’s
Menu system ( item
3-3 ) to provide frequency readout on 50 MHz while
transverting to 28 MHz. See the discussion in the
section to follow.
Frequency conversions now will be taking place,
based on an HF range of 28 ~ 30 MHz, with con-
version either to 50 ~ 52 MHz, or 52 ~ 54 MHz.
Examples of this conversion process are:
1) MARK-V FT-1000MP: 28.12345 MHz, FTV-
1000 ’s BAND switch: 50-52 position. Actual fre-
quency is 50.12345 MHz.
2) MARK-V FT-1000MP: 29.12345 MHz, FTV-
1000 ’s BAND switch: 52-54 position. Actual fre-
quency is 53.12345 MHz.
3) When entering frequencies directly from the
keyboard, be sure to enter the appropriate “MHz”
digits (either [
2
] – [
8
] or [
2
] – [
9
]) so as to set the
frequency correctly. If you want to enter
“
50.56789 MHz,” press [ ENT

Advice : You can also change the frequency read-
out to a “50 MHz format” from the standard “28 MHz
format” via
Menu 3-3
on the MARK-V FT-1000MP.
See the box on the next page.
5. Set the RF preamplifier to “ 1 ” or “ 2 ,” according to
the level of the background noise in your location. If
preamplifier “
1 ” provides enough gain to produce
S-meter movement on the MARK-V FT-1000MP’s
S-meter (with only background noise present), the
additional gain of preamplifier “
2 ” will not be neces-
sary. However, in extremely quiet locations, or when
using large, quiet antennas for such applications
as EME (moonbounce), preamplifier “
2 ” may pro-
vide a significant improvement in signal-to-noise
ratio, although the strong signal handling capability
of preamplifier “
1 ” is slightly superior to that of
preamplifier “ 2 .”
