Icom Ic-Pcr1000 Communications Receiver For Computer Instruction Manual

							2PANEL DESCRIPTION
8 @3DELAY TIME scroll bar
This sets the period in which a scan pauses after receiving a
signal. Moving the knob to the right increases the period; to
the left decreases the period.
@4SPEED (scan speed) scroll bar
Sets the speed at which scans search through frequen-
cies/memories for signals. Moving the knob to the right in-
creases the speed; to the left decreases the speed.
@5VSC (Voice Scan Control) button
Turns the voice scan control function on and off. This function
detects whether signals are modulated (contain voice or
music components, etc.) or not.
@6AF (audio frequency) GAIN scroll bar
Adjusts the audio output.
@7MUTE button
Turns the mute function on and off. Used to temporarily mute
audio output.
@8SQUELCH scroll bar
Adjusts the squelch level.
@9MONI (Monitor) button
Turns the monitor function on and off. The monitor function is
used to temporarily open the squelch to listen to weak sig-
nals.
#0ATT (Attenuator) button
Turns the attenuator on and off.#1AGC (Automatic Gain Control) button
Turns the AGC function on and off.
#2NB (Noise Blanker) button
Turns the noise blanker function on and off. The noise blanker
is used to reduce pulse type noise.
#3AFC (Automatic Frequency Control) button
Turns the AFC function on and off. This function tracks the re-
ceive signal when drifting.
#4Center button
After moving a signals’ passband position with the [IF-SHIFT]
scroll bar, this button returns it to the center position.
#5IF-SHIFT (IF shift) scroll bar
Sets a signals passband position. Moving the knob to the
right sets the passband higher, moving the knob to the left
sets the passband lower.
#6FILTER (IF filter) buttons
Change the IF filter in use. The [WIDE] button selects a wider
filter, the [NAR] button selects a narrower filter.
- Usable IF filters vary according to receive mode.
#7T (Tone squelch) button
Shows/hides the [TONE SQUELCH] dialog box for setting
tone squelch tone frequencies.
#8Receive mode buttons
Select a receive mode. Using the [AUT-M] button to select au-
tomatic mode also selects a receive mode.

PANEL DESCRIPTION
#9+200k/–200k (Max. frequency span value) indicators
Indicate the upper and lower observable frequency limits
around a receive frequency.
In the diagram, the upper and lower limits are +200 kHz and
–200 kHz.
$0Center frequency indicator
Indicates the center frequency of the frequency span; this is
for the currently received frequency.
$1Frequency span indication
Indicates the frequency span selected with the [SPAN+/–] but-
ton.$2LIMIT indicator
Indicates when the tuning step is greater than the automatic
sweep step setting.
In the diagram, the tuning step is greater than the automatic
sweep step setting and the tuning step (TS) and the sweep
step width are not the same.
$3Sweep step indicator
Indicates band scope sweep step.
$4STOP button
Stops the band scope (sweep) function.
$5START button
Starts the band scope (sweep) function which is used to ob-
serve signal conditions around the receive frequency.
$6II (sweep pause) button
Pauses/resumes a band scope function sweep.
$7SPAN +/– buttons
Select one of four levels for the band scope frequency span.

PANEL DESCRIPTION
Radio screen
The radio screen shows 10 memory channel buttons and fre-
quency readout, etc. like a typical stereo tuner—this provides
the simplest operation for monitoring your most-listened-to-
stations, such as AM/FM broadcasting and TV, etc.
See the on-line help for the radio screen details.
Communications receiver
screen
The communications receiver screen shows S-meter (signal
strength) level, a large frequency readout, keypad, etc.—what
you would see on the front panel of a typical communications
receiver. 
See the on-line help for the communications receiver screen
details.
