Change Primary
Operating Mode
(Voice, CW, Data)
Press [Mode] Each time [Mode] is press, the DSP-59Y the operating mode changes
to the next mode.
Select Setup modes Press [Shift+Mode] Press [Shift+Mode] 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.
Store a setting in
memory Press [Shift+Rcl/Sto+{#}]
# = 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/Sto+{#}]
# = 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/Sto+Rcl/Sto] Recalls previous setting before the memory recall. Allows quick toggling between two operating settings.
Change power-up
mode Press [Shift+Rcl/Sto+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 [Byp/AGC] Actual operation varies with mode of operation. Generally routes signal
past all signal processing.
Turn AGC on/off Press [Shift+Byp/AGC] Optimizes signal levels for best filter performance and enhances
listening by minimizing audible signal level variation.
Enable random noise
reduction Press [NR] An adaptive multi-tone filter that can remove multiple tones simultaneously.
Voice Mode
Feature Required Actions Description/Notes
Adjust high pass
filter Press Tune knob to set Tune knob indicator pointing left. Turn Tune knob
to select value.
By turning the Tune knob with the tune indicator pointing left, you can
adjust the high pass filter from 100 Hz to 1000 Hz
Adjust low pass
filter Press Tune knob to set Tune knob indicator pointing right. Turn Tune
knob to select value.
By turning the middle knob with the tune indicator pointing right, you
can adjust the low pass filter from 1000 Hz to 5000 Hz
Enable random noise
reduction Press [NR] Can be very effective in reducing offending background noise.
Adjust
aggressiveness of
noise reduction
Press [Shift+NR], 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 Tune knob
to change Notch Center Frequency.
Press Tune knob to change indicated
function of knob. Rotate Tune knob to
adjust Notch Bandwidth. Accept by
pressing [Ent/Clr].
Rotate Tune knob until unwanted signal disappears. Press Tune knob
to change indicated function. Rotate Tune 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 [Shift+
Ent/Clr]. Removes notch filter after it is no longer needed.
Change freq of AM
line noise filter Press [Shift+Mode]. Turn Tune knob
until Voice appears. Press [Ent/Clr] to
accept. Turn Tune knob until AM Line
Noise appears. Press [Ent/Clr] to
accept. Turn Tune knob until desired
value is viewed. Press [Ent/Clr] to
accept, press [Shift+Ent/Clr] 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 Press Tune knob to set Tune knob indicator pointing left. Turn Tune knob
to select value.
By turning the Tune knobwith the tune indicator pointing left, you can
adjust the center frequency from 200 to 2100 Hz.
Adjust CW
bandwidth Press Tune knob to set Tune knob indicator pointing right. Turn Tune
knob to select value.
By turning the middle knob with the tune indicator pointing right, you
can adjust the CW bandwidth from 10 Hz to 600 Hz.
Enable random noise
reduction Press [NR] Can be very effective in reducing offending background noise.
Turn on/adjust notch
filter Press [Shift+Tone]. Turn Tune knob
to change Notch Center Frequency.
Press Tune knob to set Tune knob
indicator pointing right. Rotate Tune
knob to adjust notch bandwidth Accept
by pressing [Ent/Clr].
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 [Shift+
Ent/Clr]. Removes notch filter after it is no longer needed.
Turn CW marker
tone on/off Press [Tone]. Turn Tune 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 Tune
knob to shift output CW pitch you hear.
Press Tune knob to set Tune Knob
indicator pointing right. Turn the Tune
knob to adjust the incoming CW pitch.
Press [Shift+Function] or press
[Ent/Clr] 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
[Shift+Ent/Clr] 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 Tune knob to
set Tune knob pointing right. Turn
Tune 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 [NR] 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 1 of DSP-59Y 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.
