ICOM IC-7200, serial number 0201073
with this interface — eliminating the need
for an external computer/radio interface for
digital modes such as PSK31 or RTTY.
A traditional ICOM
REMOTE jack
provides another means for control of the
’7200 from your computer if you have the
appropriate CI-V interface and software.
Jacks for
ALC (automatic level control) and
SEND (TR relay control) are available for
connection to a linear amplifier. A
TUNER
connector provides an interface to control
an optional external antenna tuner.
The
ACC jack is a 13-pin connector
that provides a transmit control line, a data
line and keying line; ALC voltage line; a
1 A, 13.8 V dc output; RTTY keying control;
a modulation input; an audio line output and
a squelch control output. A matching plug
is supplied with the ’7200, providing a set
of color-coded pigtails for the accessory
connector inputs and outputs.
Band Selection
The ’7200 includes a stacking register for
each band, selected with the numeric keys.
Holding the
BAND button activates stacking
register selection and the word
BAND is dis-
played. Pressing the numeric key for the band
you want will automatically set the active
VFO to that band with the same configuration
(frequency, mode, filter, preamplifier, and so
on) that you last used on that band.
The ’7200 has two separate VFOs (A/B)
and a 7 + 1 digit frequency display (a 1 Hz
digit is displayed in some situations). Fre-
quency can be set manually with the main
tuning dial or entered directly using the
numeric keys. A one button equalizer copies
VFO A into VFO B.
While using the main tuning dial, there
are three methods of controlling the tuning
step (rate) of the main dial: tuning step,
auto tuning step and
1
⁄4 tuning function.
The dial can also be locked by holding the
SPCH button. The default is a 10 Hz step.
Pressing the
TS button activates the tun-
ing step, which is indicated by a
 symbol.
Holding the button gives you the choice of
five tuning steps: 0.1, 1, 5, 9 and 10 kHz.
The auto tuning step function senses
when you are rotating the main dial rap-
idly and increases the tuning step. This is
convenient, for example, to move from the
CW to the phone portion of the band more
quickly. The auto tuning step speed varies
between two and five times the normal rate,
depending on its settings.
Finally, the ’7200 includes a
1
⁄4 tuning
function used in the SSB data, CW and RTTY
modes. While
1
⁄4 tuning is active, the tuning
step of the main dial is reduced to about 370
Hz per turn. This permits the precise tuning
required by some digital modes.
Direct frequency entry is activated by
pressing the
F-INP ENT button, entering the

frequency and pressing the F-INP ENT again
to set the active VFO to the entered fre-
quency. If you make an error, pressing
SET
returns you to the previous frequency.
The receiver incremental tuning (RIT)
feature permits you to “trim up” the sound
of a received signal to maximize readability.
The
RIT control is located at the lower right
and can adjust the receive frequency about
±10 kHz.
A final tuning aid is a band edge marker.
When activated, the ’7200 will issue a beep
whenever you cross the edge of the current
amateur band.
Modus Operandi
The ’7200 has seven mode choices:
LSB/USB, CW/CW-R (CW Reverse; shift
to the opposite sideband), RTTY/RTTY-R
and AM; FM is not included. Pressing the
MODE button changes the operating mode
in a circular fashion, LSB-CW-RTTY-AM-
LSB and so on. To access USB and the
reverse modes, press
