All Modes
Feature Required Actions Description/Notes
Change Primary
Operating Mode
(Voice, CW, Data)
Press [Mode] Each time [Mode] is press, the DSP-599zx the operating mode changes to
the next mode.
Select Test or Setup
modes Press [Shift+Mode] Press [Shift+Mode] once for Test mode and twice for Setup mode.
Cancel [Shift] action Press [Shift] or wait three seconds Pressing [Shift] twice in a row with no other button pressed cancels [Shift].
By waiting three second without any other action, [Shift] will time out.
Turn speaker on/off. Press [Spkr/Chan] Pressing [Spkr/Chan] toggles the speaker on and off.
Change channels Press [Shift+Spkr/Chan] Pressing [Shift+Spkr/Chan] toggles between channels.
Store a setting in
memory Press [Shift+Rcl/Store+{#}]
# = memory number (1 - 6) Stores a common operating configuration to memory for easy recall. Stores
every setting except audio gain control position. Six memories available.
Recall a stored setting Press [Rcl/Store+{#}]
# = memory number (1 - 6) Recalls a common operating configuration from memory. Recalls all settings
except audio gain control position. Six memories available.
Restore previous
setting Press [Rcl/Store+Rcl/Store] Recalls previous setting before the memory recall. Allows quick toggling between two operating settings.
Change power-up
mode Press [Shift+Rcl/Store+Mode] Stores the operating mode and channel that you wish to power up with. Can be changed at any time by repeating process.
Bypass all settings Press [Bypass] Actual operation varies with mode of operation. Generally routes signal past
all signal processing.
Turn AGC on/off Press [AGC] Optimizes signal levels for best filter performance and enhances listening by
minimizing audible signal level variation.
Enable random noise
reduction Press [Random] An adaptive multi-tone filter that can remove multiple tones simultaneously. Removes multiple heterodynes almost completely.
Voice Mode
Feature Required Actions Description/Notes
Adjust high pass filter Turn left knob [High Pass] By turning the left knob, you can adjust the high pass filter from 100 Hz to
1000 Hz
Adjust low pass filter Turn middle knob
[Low Pass] By turning the middle knob, you can adjust the low pass filter from 1000 Hz
to 5000 Hz
Enable random noise
reduction Press [Random] Can be very effective in reducing offending background noise.
Adjust aggressiveness
of noise reduction Press [Shift+Random], turn left knob to
adjust. Press left knob to accept. The aggressiveness can be adjusted from one to nine with default value of
five. The higher the value, the greater the noise reduction.
Turn AM line noise
filter on/off Press [Function]. LED illuminated
indicates on. This does not work on SSB signals. It is designed primarily for AM signals.
Eliminate heterodyne
tones Press [Tone]. LED illuminated indicates
on. The automatic filter can virtually eliminate multiple heterodynes and reduce
CW and FSK data signals.
Turn on/adjust notch
filter Press [Shift+Tone]. Turn left knob
[Center Freq] to change Notch Center
Frequency. Rotate middle knob to adjust
Notch Bandwidth. Accept by pressing left
knob.
Rotate left knob until unwanted signal disappears. Rotate middle knob to
adjust width of filter. The lower the value the narrower the filter. Filter
widths 1 - 5 are single notch filters. Filter widths 6 - 9 are dual notch filters
for data signals. As a reminder, a


or 

will be displayed.
Turn off notch filter Press [Shift+Tone] or press middle knob.Removes notch filter after it is no longer needed.
Change freq of AM
line noise filter Press [Shift+Mode] twice. Turn left knob
until Voice appears. Press left knob to
accept. Turn left knob until AM Line Noise
appears. Press left knob to accept. Turn
left knob until desired value is viewed.
Press left knob to accept, press middle
knob to cancel and escape.
You can select between 50 and 60 cycles. Your choice will depend upon the
frequency of the local AC electrical power.

CW Mode
Feature Required Actions Description/Notes
Adjust center
frequency Turn left knob [Center Freq] By turning the left knob, you can adjust the center frequency from 200 to 2100 Hz.
Adjust CW bandwidth Turn middle knob [Bandwidth] By turning the middle knob, you can adjust the CW bandwidth from 10 Hz
to 600 Hz.
Enable random noise
reduction Press [Random] Can be very effective in reducing offending background noise.
Turn on/adjust notch
filter Press [Shift+Tone]. Turn left knob
[Center Freq] to change Notch Center
Frequency. Rotate middle knob to adjust
notch bandwidth Accept by pressing left
knob.
Rotate left knob until unwanted signal disappears. Rotate middle knob to
adjust bandwidth of filter. The lower the value the narrower the filter.
Turn off notch filter Press [Shift+Tone] or press middle knob.Removes notch filter after it is no longer needed.
Turn CW marker tone
on/off Press [Tone]. Turn left knob to adjust
marker tone frequency. The tone is generated at the bandpass filter center frequency. Use the marker
to center a wide bandpass filter (300-600 Hz) on a signal by matching the
marker tone pitch to the signal pitch by ear.
Enable CW tone pitch
shift Press [Shift+Function]. Rotate left knob
[Center Freq] to shift output CW pitch
you hear. Turn the middle knob to adjust
the incoming CW pitch. Press
[Shift+Function] or press the left knob to
accept the pitch shift..
Shift CW tone pitch to another frequency. Works well with receivers that
have non-adjustable, relatively high pitch CW tones.
Disable CW tone pitch
shift Press [Shift+Function]. Press the middle
knob to disable the pitch shift.. Return CW tone pitch to received tone.
Data Mode
Feature Required Actions Description/Notes
Select Data tuning
display Press [Shift+Function].
Adjust data carrier
detect (DCD) Press [Shift+Function] to turn data
tuning display on. Press [Function] to
switch middle knob from [Bandwidth] to
[DCD]. Turn middle knob [DCD] to clean
error free copy.
DCD value is displayed in the lower left of the data tuning display. Range is
0 - 9. The greater the value, the higher the DCD threshold. Setting the DCD
to “0” (zero) turns DCD off.
Enable random noise
reduction Press [Random] Not designed for data but does work for some conditions.
Enable RTTY FSK
test signals Press [Tone]. If baud rate in non burst data mode is 75 baud or less, a diddle tone is activated. If baud rate is 100 baud or higher, a space-mark reference
calibration tone is enabled.
Enable RTTY FSK
test signals Press [Shift+Tone]. If baud rate in non burst data mode is 75 baud or less, a “RYRY” test tone is activated. The signal is centered at 2210 Hz with a frequency shift of +/- 85
Hz. Baud rate is determined by RTTY parameter settings. If baud rate is 100
baud or higher, no tone is enabled.
RTTY Modem Always on in RTTY operation See Section 2 of DSP-599zx Operating Manual for proper connection
information.
RTTY Remodulator Press [Function] in RTTY operation Sends regenerated RTTY signal to line output. You can still monitor the
incoming RTTY tones through the speaker/headphone.
