Operation
The FT-1000MP can be used with the optional
Yaesu FL.-7000/VL-1000 which provides automat-
ic band switching via digital band data output from
the BAND DATA jack on the rear panel of the trans-
ceiver. Most other amplifiers can be adapted to
operate with the FT-1000MP; however, 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 FT-1000MP
is
described in the table below.

Operation with QSK Amplifiers
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. After mak-
ing the RF and Tx/Rx switching connections de-
scribed below, you may need to adjust the ALC
output level of the linear so that it is not overdriven
by the FT-1000MP. Your linear's manual should
describe how to do this.
If using an FL-7000, connect optional cable
E-767
(P/N D4000019)
from the transceiver
BAND DATA jack to the amplifier ACC-2 jack. This
provides automatic band selection for the linear,
as well as QSK Tx/Rx switching control. If using
another manufacturer's QSK linear, and if it can
be switched with less than 100 mA of DC voltage
below 15 V, you can connect the the Tx/Rx switch-
ing line for the linear to pin 2 of the BAND DATA jack,
and the linear's exciter-enable output to pin 8 of
the BAND DATA jack. This line must be held to
ground to enable transmission after the linear is
ready for excitation from the FT-1000MP. If your
QSK linear requires more than 100 mA or uses
more than 15 V for T/R relay switching, you will
have to provide a suitable external interface tran-
sistor, controlled by pin 2.
