The MARK-V FT-1000MP Field can be used with
the optional Yaesu FL-7000 or VL-1000 Linear Ampli-
fier, providing automatic band switching via digital band
data output from the BAND DATA jack on the rear panel
of the transceiver. Most other amplifiers can be adapted
to operate with the MARK-V FT-1000MP Field; how-
ever, the main points to be concerned with are the
switching requirements of the amplifier, and if QSK (full
break-in) operation is desired. The linear amplifier Tx/
Rx switching capability of the MARK-V FT-1000MP
Field is described in the table below.

Connect the RF output from the transceiver ANT
jack (A or B) to the RF input jack of the linear. Connect
the ALC output from the linear to the EXT ALC jack on
the rear of the transceiver (see the "About ALC" dis-
cussion below). After making the RF and Tx/Rx switch-
ing connections described below, you may need to
adjust the ALC output level of the linear so that it is not
overdriven by the MARK-V FT-1000MP Field. Your
linear's manual should describe how to do this.
If using a VL-1000, connect the BAND DATA Cable
(supplied with the VL-1000) from the transceiver BAND
DATA jack to the amplifier BAND-DATA 1 jack; this will
provide automatic band selection for the linear, as well
as QSK Tx/Rx switching control. You may also con-
nect a user-constructed control cable (refer to VL-1000
manual for details) from the transceiver REMOTE jack
to the amplifier BAND-DATA 2 jack to provide auto-
matic amplifier tune-up for the linear using the MARK-
V FT-1000MP Field. Press the VL-1000's front panel
ATT switch to disable the 3 dB input RF power attenu-
ator.
