RANSMISSION
A separate, dedicated “29 MHz” band is provided
on the MARK-V FT-1000MP, allowing you to operate
both on 28 MHz in narrow-band modes, and above 29
MHz using narrow-band FM. This relieves you of the
need to change all your configurations when switching
voice modes.
For transmission, the only control on the front panel
you need be concerned about is RF PWR. Microphone
gain for FM is set via the separate FM MIC control in
the top access panel, and normally needs no adjust-
ment after leaving the factory. If you receive signals
reports of low audio with a strong carrier, you may want
to increase the gain. If you notice distortion in the trans-
mit monitor, you may want to decrease it. Otherwise,
we suggest leaving it alone. Remember that the ap-
parent modulation level on 29 MHz will be less than
you are accustomed to on VHF, due to international
regulations restricting the maximum deviation to ±2.5
kHz.
All you need to do for most operation is set the
METER selector to the “PO” position, and adjust the
RF PWR control for the desired output while transmit-
ting. If you need full power, keep your transmissions to
three minutes or less, with the same time for recep-
tion. Otherwise, set the power output to 100 Watts or
less, and you should never encounter any duty cycle
limitations.
You can use the VOX circuit for t/r switching, if de-
sired, and the transmit monitor to listen to your signal.

FM Repeater Operation
Several features are available for operation on FM
repeaters above 29 MHz, which typically use 100-kHz
splits.
To locate these repeaters, you can ask around the
calling channel (29.6 MHz), or you may want to load a
block of memory channels (see page 67) with 50-kHz
frequency multiples from 29.61 to 29.7 MHz (and FM
mode, of course). Then set the squelch so that the
receiver is silent on a clear channel, and hold the mi-
crophone UP/DWN keys to scan the memories.
Repeater Shift
- When you find a repeater, press
the [RPT] button, once for “–” shift (to transmit 100
kHz below your receiving frequency). Pressing it again
will select “+” shift, but this is not used above 29.6 MHz.
Press it once more to re-
turn to simplex. Try a quick
identification transmission
to make sure you have the
shift right.
Repeater TX Offset
- For repeaters not using the
standard 100 kHz offfset, you can change the default
offset between 0 ~ 200 kHz via
menu selection 6-9
.
CTCSS Tone
- A low-level 88.5-Hz subaudible tone
is transmitted to access closed repeaters. Should a
different CTCSS tone be required, you can choose any
one of 33 standard tones via
menu selection 6-7
.
Tone Type
– Continuous (CTCSS) or burst tone
transmission is enabled from
menu selection 6-8
