Operating the PicoKeyer-Plus:
Once your PicoKeyer-Plus is assembled, mounted in the cabinet and has the battery installed, it’s time to connect your paddles
and transmitter or transceiver and take a little time to read this manual to learn how to use your PicoKeyer’s features.
This is the connections end of your PicoKeyer. The left
hand jack is for your paddles (input); the right hand jack is
for your transmitter or transceiver (output).
This is the controls end of your PicoKeyer. The speed
control knob is on the right, the memory/setup pushbutton
is on the left.
The Speed Control
This is the control you will probably use the most often. The code speed can be adjusted from 5 to 40 words per minute
(WPM) by simply turning the speed control knob. You may notice that the speed will decrease to 5 WPM as you rotate the
knob counter-clockwise, then suddenly jump to 13 WPM. This is a special feature known as “Dual-Set Speed”.
Two Morse code speed settings are available for your use. The current speed is the speed at which the keyer is operating,
regardless of whether that speed is derived from the speed pot or the menu. The stored speed is saved in the chip’s internal
non-volatile memory, and is used when the speed pot is turned to its minimum position. At any time you may use the speed
adjustment to set any speed from the low range setting to the high range setting. Setting the speed with the pot does not affect
the stored speed, which will always be available by simply turning the pot to its full counter-clockwise position. This feature
can be very useful; for example, you can keep your speed set at a constant, favorite speed, but have the option of rapid
QRS/QRQ to answer faster or slower stations. Or, you can simply ignore the stored speed and always use the pot for speed
control –it’s up to you.
One thing to note: you can set the stored speed anywhere from 5 to 63 WPM –and it doesn’t have to be within your pot speed
control range. You can also set the range of the speed control to whatever is best for you. See the Range (RL & RH)
commands in the “Setup Menu Commands” section.
The Pushbutton
One pushbutton switch is used for memory messages and setup. Exactly how this works will be different depending on
whether you are using a straight key or a paddle, and your preferences. We’ll cover the default settings first, then discuss some
variations.
Pressing and immediately releasing the button once (a “tap” of the button) will send the message stored in Message 1 (M1), if
there is one stored. You can also use the paddle inputs to quickly send messages M2, M3 and M4.
To send M2: Briefly press the button while you tap the DOT paddle.
To send M3: Briefly press the button while you tap the DASH paddle.
To send M4: Briefly press the button while you tap BOTH paddles together.
Pressing and holding in the pushbutton more than about half a second will also allow you to send messages M2, M3 and M4.
If you wish to send the contents of message memory 2 (M2), release the button when you hear two dits, sent via the sidetone
only. Similarly, to send message 3 or 4 (M3 or M4), hold in the button until you hear three or four dits, then release. This is
useful for sending messages while using a straight key.
To enter setup mode, continue to hold the button down until you hear the keyer’s command prompt, a Morse question mark “?”
character. This tells you that the keyer is waiting for your input. In setup mode, you will normally just send the letter of the

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 3 of 19
setting you want to check or change –for example, S to set the stored speed. That will let you make changes to a setting until
you tap the button to return to command mode. Each time you return to command mode, you will hear the “?” prompt.
BUT –this method won’t work with a straight key, since the PicoKeyer can’t copy your commands from a straight key –only
from paddles. If you are using a straight key, the keyer will revert to Button command mode. In this mode, you simply hold
the button and listen to the keyer send the letters for each menu setting, one by one. When you hear the one you want to check
or set, just release the button. If you don’t want to carry a “cheat sheet” with the commands listed and can’t remember them,
you can also set Paddle Command Mode to use this mode for setup all the time (see setup menu item “C”).
Power control
Note that your PicoKeyer does not have a power switch! The microprocessor “brain” of the keyer will go into a low-current
sleep mode after about ½ second with no inputs from either paddle. In sleep mode, the keyer chip draws so little current that
the internal battery can last for years. As soon as you touch a paddle, the chip instantly “wakes up” and continues its normal
operation. At this point the keyer will operate as a normal iambic keyer, sending dots and dashes with automatic spacing and
timing according to paddle inputs and stored settings.
Replacing the Battery
The battery in your PicoKeyer-Plus should last for a long time –anywhere from several months to several years. Battery life
depends on a few factors:
Frequency of use. Obviously, the more you use the keyer, the shorter the battery life will be.
Sidetone. The sidetone speaker draws more power than the rest of the keyer. Using the sidetone speaker will reduce
battery life –but you should still only have to replace it once in a great while.
Straight key use. Leaving a straight key plugged in while not using the keyer will drain the battery within a few
weeks. If you use a straight key, unplug it when you’re not operating.
Beacon mode. The keyer does not sleep between messages while in beacon mode. If you use your PicoKeyer to
control a beacon full time, you should use an external power source. This can be as simple as a pair of series AA or
AAA alkaline cells, or you can use the kit’s Zener diode and resistor for power sources up to about 20 Volts DC.
Battery replacement is straightforward –just remove the two screws from the cabinet bottom, open the cabinet and pop the
coin cell battery out of its holder. Hold the setup button in for a couple of seconds to make sure power is completely drained,
then release the button and install the new battery. All of your settings and messages will be retained even with no battery
power.
If you should need to replace the battery in your keyer, you will need a CR2032 or equivalent lithium cell. These are very
common and are used in many devices from garage door openers to car remotes to thermometers and medical monitors. You
can order high quality CR2032 cells from www.HamGadgets.com.
Master Reset
In case you happen to get the settings to a point where the keyer is unusable, you can easily return your PicoKeyer to its default
settings. Open the case and remove the CR2032 coin cell from its holder. Push the setup button with the battery removed –
this is to ensure that power is completely removed from the chip. Now, hold the button in while you insert the battery into its
holder. At this point the keyer will send “RESET?”; tap either paddle to perform a complete reset. If you don’t want to do
that, just tap the button again to exit.
Straight Key Mode
The PicoKeyer can automatically detect and use a properly wired straight key if one is plugged in when power is applied.
During its power-on program, the PicoKeyer checks to see if either paddle input is grounded. If one input is shorted, the other
input is assumed to be a straight key. This way you can plug in a straight key wired to a mono plug and use it without any
changes or adjustments. Be aware that while the menu will still function, many parameters will not be adjustable (and would
not apply to a straight key anyway). You will not be able to record messages while using a straight key. If your PicoKeyer is
in the plastic cabinet, you may find it more convenient to switch between paddles and a straight key using the Kmenu setting.

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 4 of 19
Sidetone
The PicoKeyer’s sidetone is a square wave audio signal generated by the microprocessor. Sidetone can be turned on or off,
and the audio frequency can be changed from the setup menu. There is a very noticeable peak in the response of the on-board
speaker at roughly 2 kHz; if your PicoKeyer is installed in the plastic cabinet you’ll probably want to find this peak so you can
hear it with the case assembled. The default setting should be at this audio peak.
Keying the transmitter
The PicoKeyer will key any solid state, tube or hybrid transmitter or transceivers that uses a keying voltage of 60V or less,
positive or negative. If you are using the keyer with a negative keyed transmitter, you will need to make sure the KEY and
RIG jacks are isolated from each other –this is the case when the keyer is mounted in its plastic cabinet.
Your transmitter or transceiver may need either a mono or stereo cable. It depends on the rig; check your owner’s manual for
details for connecting a straight key to your transmitter. The PicoKeyer’s output acts like a straight key, so you’ll use the
method for connecting a straight key. Remember to disable the rig’s internal keyer, if it has one.
You may want to use a stereo cable with a radio that requires a mono cable. There’s a very simple modification you can make
to your PicoKeyer-Plus to accommodate this. The output (RIG) jack is a 3.5mm stereo jack, with only the sleeve and tip
contacts used. You can add a short wire jumper between the sleeve and ring contacts, as shown in the diagram below. A piece
of cut-off component lead is perfect for this.
View from bottom (solder) side of the board.
If you intend to use the PicoKeyer with a rig requiring grid-block or cathode keying voltages over 60 V, you will need to use a
separate high voltage keying adapter. The Universal Keying Adapter 3 available from NØXAS at www.hamgadgets.com is
optically isolated and will handle solid-state, grid-block or cathode keyed transmitters at up to 400 V. Of course, you can
always build your own!
Keying Modes (What’s Mode A, Mode B and Ultimatic??)
There have been a couple of different operating modes for iambic keying that have evolved over the years. Modes
A & B are simply a matter of when the keyer checks for input from the paddles. In iambic mode A, the keyer only
checks for paddle inputs after the end of each dot or dash. In iambic mode B, on the other hand, the keyer will
check for paddle input during each dot or dash.
In practice, this can mean that you get “extra” or “dropped” dots or dashes at the end of a character, depending on
how you send. If you find that the keyer often drops the last dot or dash in a character, or you often get an extra dot
or dash at the end of a character, try switching between modes A & B and see which one best suits you. I find that
Mode B worked best for me when using a single-lever paddle, while Mode A works best with a dual-lever paddle.
Ultimatic mode is a different way of handling iambic keying. In modes A & B, if the keyer sees both paddles
closed it will alternate sending dots and dashes. Ultimatic, on the other hand, will send dots or dashes according to
the last paddle to be pressed. For example, to send the letter P in mode A or B, you would close the dot paddle,
then close the dash paddle and release the dot paddle for the two dashes, then release the dash paddle and close the
dot paddle for the last dot. In Ultimatic mode, you would close the dot paddle and hold it closed, close the dash
paddle for the two dashes, then release it for the last dot. Some letters are easier to send and require less effort

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 5 of 19
using Ultimatic mode. It’s a little bit of an adjustment from regular iambic keying; it took me a couple of hours of
practice to get used to it.
Selecting a keying mode (A, B or Ultimatic) is largely a matter of personal preference. There is no one “right” way
that works for everyone; find which works best for you.
Using Your Keyer with a Handheld or FM Rig (“MCW” Mode)
One of the unique features of your PicoKeyer-Plus is MCW mode (menu option “T” for sidetone, select “M” for
MCW). In this mode, the keying output can be used to trigger the PTT input of a VHF or UHF handie-talkie or FM
mobile rig, allowing you to use your FM rig for Morse code. This is not CW (Continuous Wave) operation, nor is
it true MCW (Modulated CW) mode –it’s really just an FM transmission, with audio Morse code tones sent instead
of voice. This makes it easy, for example, to have a CW practice net using a local repeater –with the blessing of
the repeater operator, of course –or a simplex frequency. Those participating don’t need HF privileges or HF
equipment to learn and practice Morse code on the air.
It is not possible to give detailed instructions for attaching your keyer to every rig on the market. You will need to
take a look at your rig’s manual to determine how the audio and PTT signals from the keyer need to be connected.
Doing it wrong could possibly damage your rig and/or your keyer! However, presented here are a few examples
that you may find useful for setting up your station for FM code practice. Refer to the operator’s manual for your
rig for specific requirements for PTT and audio.
Using MCW mode requires making soldered connections to a set of solder pads (JP1), which is located underneath
the battery holder on the PicoKeyer’s printed circuit board. You can “tack solder” wires in place using a low
wattage pencil type iron, 25-35 Watts maximum. Be sure to remove the battery before soldering.
Figure 1 - Keying Yaesu and similar HTs
In Figure 1, we see the most common method that will work with
many handheld transceivers from Alinco, Yaesu, Icom and others
that use a similar combined audio/PTT scheme. This value of the
capacitor is not critical, and can be several times smaller or larger.
A 2.2K or 2.7K Ohm resistor is used in series with the PTT line to
key the rig. In most cases, GROUND is connected to the sleeve
(barrel) of a 2.5mm stereo plug, and PTT/Audio is connected to the
tip –but again, be sure to consult your rig’s manual.
Figure 2 - Keying HTs with separate audio & PTT
Figure 2 shows the method for using with with separate audio and
PTT lines. Consult your rig’s manual for the correct plug and
wiring to use.
Figure 3 - Keying ICOM and similar HTs
The diagram in Figure 3 illustrates the method used by some
Icom handhelds. If your HT does not respond with the
circuit in Figure 1, try this one instead.

Figure 4 - Keying FM mobile rigs
Figure 4 shows the method used with mobile or fixed station rigs.
You will likely find it easiest to connect the keyer via the packet
data connector. The schematic shows an optional audio level
control potentiometer that may or may not be needed.

About Setup Mode
In setup mode, all except the U, M, V and F commands share a common method of reviewing and changing the
current setting. In general:
Send the letter corresponding to the setting you want (M, S, etc). In “Button” command mode, hold the
button until you hear the letter of the item you want to review or change, then release it.
The keyer will respond with the current setting.
For most commands, simply use the dot or dash paddle to change the setting. Tapping either paddle will
step through the possible settings. The dash paddle “steps up”, the dot paddle “steps down”.
Tap the setup button to return to the “?” command prompt (“Paddle” command mode). In “Button”
command mode, a short tap of the button will exit setup mode, while holding it will advance to the next
setting.
There are some exceptions to this rule. The specifics for the U, M, V and F commands are detailed below.
PicoKeyer Setup Menu Commands
U
Tune mode: Tune mode is used to send either a steady carrier or a series of dots for adjusting or testing
your station equipment. While in tune mode, each paddle acts as an on/off toggle switch. Tap the dash
paddle to turn a steady carrier on or off. Tap the dot paddle to start or stop a continuous stream of dots.
This is gives you a 50% duty cycle signal that is preferred by some operators as a way to tune up with
less stress on final PA, tuner and antenna components.
S
(Default:
13 WPM)
Speed: The keyer will always announce the current speed in WPM. If the current speed is not the
same as the stored speed, the keyer will announce the current speed followed by a slash and the stored
speed. For example: Assume the stored speed is 13 WPM, any you have the optional speed pot
installed and set for 20 WPM. The keyer will announce “20/13”. If you have the pot set to its
minimum, you will be using the stored speed and the keyer will only announce the stored speed, since it
is the same as the current speed. It sounds more complicated than it is; play with it a little and you’ll
get the hang of it.
You can adjust the stored speed from the menu. Tapping the dot paddle will decrease the speed by one
WPM, or the dash paddle will increase it. Holding either paddle will continuously increase or decrease
the speed, with a dot or dash sent at the new speed for each step. When the paddle is released, the keyer
will again announce the current speed setting and the stored speed, if it is different from the current
speed. Speed may be set from 5 to 60 WPM.
M
Messages: Four message memories are available, numbered 1 through 4. When you enter Message
mode, message 1 will be the default selection. You have a choice of actions available to you when in
memory mode, selected by sending a single character from your paddle:
Send the number 1, 2, 3 or 4 to select a message memory. The keyer will respond by sending 1,
2, 3or 4to confirm.
Send P(Play) to listen to the contents of the currently selected memory. The keyer will play
the message, followed by the Morse prosign AR and the message number.
Send R(Record) to record a new message. If a message already exists it will be erased and
replaced. The keyer will respond with Kto let you know it is in record mode. Enter your
message, with exaggerated word space but normal spacing between characters. If you make a
mistake when recording the message, just send 8 dots and the keyer will backspace one word.
You will hear a single dot to confirm this (two dots means you are at the beginning of the
message). Tap the setup button once when you are finished recording. The keyer will send R
and the message number to indicate the end of the message. You can then Play the message
back.

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 8 of 19
Send C(Continue) to add to or edit the message. The keyer will play the current message, then
enter Record mode. You can backspace over existing words if needed.
You can use the R, P and Ccommands to listen and change your message until you're satisfied. Each
memory can hold up to 60 characters. If you send something other than 1 - 4, P, R, or C the keyer will
respond with “?” and let you try it again.
Several special embedded commands may be used in messages. All commands start with a slash
followed by one or two characters. When playing back a message in setup mode you will hear the
command itself, not its effect –message chaining, QSO numbers, pause and beacon mode are inactive
while in setup mode. For example, you will hear /Rinstead of the word to be repeated. To store a
slash character in a message, save it as //.
/R will repeat the last word, including the word space after it. This can save a lot of memory space,
since each /R takes up only two character positions in memory. For example, to send a 3x3 CQ,
you can simply store “CQ /R/RDE (callsign) /R/RK”. This can save a lot of memory space.
/1, /2, /3 and /4 can be used to chain the message memories. The indicated message will be played
immediately when one of these commands is encountered. You can chain messages in any order.
/P will insert a pause in the message. This will cause the message to pause while you manually
send information such as manually entered QSO number, RST, etc. The message will
automatically resume after a full word space has passed with no paddle input. Hint: If you use /P,
store it immediately following the preceding characters without a word space. In other words, store
“UR RST/P …” instead of “UR RST /P …”. This prevents you starting to send before the word
space completes, which will terminate memory playback completely.
To have your message automatically repeat at timed intervals, insert the command /B (BEACON)
at the end of your message. This will cause the keyer to delay for the number of seconds set with
the B parameter (see below) and re-send the message. You can terminate beacon operation by
tapping either paddle or the button. This can be especially useful for calling CQ, or to use your
PicoKeyer to control a propagation beacon or “fox” transmitter.
To have Message #1 automatically start whenever power is applied to the PicoKeyer, store the /A
command as the first two characters in message #1. This is useful for automatically starting a keyer
used as part of a beacon station. Remember that you will still need to use /B at the end of the
message if you want it to repeat.
To send the QSO number and increment it by one, send /QI (QSO & Increment).
To send the QSO number and NOT increment it, send /QN (QSO & No increment).
To the last (previous) QSO number, send /QR (QSO Repeat). This is useful during contests if you
need to send a “fill”.
To temporarily increase the keyer speed by one WPM, send /SU (Speed Up). Note that this and
the /SD command will take effect immediately and will remain in effect only until the message is
finished. You can store multiple /SU or /SD commands to change speed by more than one WPM –
for example, /SU/SU will increase your speed by 2 WPM.
To temporarily decrease keyer speed by one WPM, send /SD (Speed Down).
To temporarily set a specific speed, send /Snn where nn is the speed you want. /S or /S0 will
resume the normal speed. For example, to send a signal report at 30 WPM and return to the normal
speed you would use /S30 599/S.
To alter the letter spacing, send /Fnwhere nis one digit, 0 through 9. This will act the same as
setting the letter spacing in the menu. For example, say you want to add a little extra space between
letters in your call sign in a CW message. You could store, “CQ /R/R DE /F2N0XAS /R/R K
/F0/B”. Remember to set the letter spacing back to your normal setting.
To insert an extra word space in your message, use the special prosign character “1M” (.------).

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 9 of 19
To insert a steady carrier, use the /Cncommand, where nis the number of seconds (from 1 to 9)
that you wish to send the carrier.
Q
QSO Number: The keyer will send the current QSO number. You can use the paddles to set the QSO
number anywhere from 1 to 255. Note that when the QSO number is auto-incrementing, it can go from
1 to 65535. To reset the QSO number to 1, simply tap both paddles at the same time.
RL
(Default: 5
WPM)
Range Low: This sets the low end of the speed control pot range. The setting is adjusted the same way
you would set the stored speed –the dot paddle will reduce the setting, the dash paddle will increase it.
RH
(Default:
40 WPM)
Range High: This sets the high end of the speed control pot range. Set the same way as the stored
speed and low range setting.
L
(Default:
OFF)
Auto letter spacing: The keyer will announce the current setting and wait for input. Automatic letter
spacing takes effect for messages sent from memory as well as code sent manually with the paddle.
0 turns automatic letter spacing off. In this mode you control the spacing between letters. This
is the default setting, and is the same as most keyers.
1 turns on auto letter spacing at the set speed. A letter space is automatically inserted if the
keyer detects no input from either paddle at the end of the space after a dot or dash.
Settings from 2 to 9 will set automatic letter spacing with longer delays. For example, selecting
2 will insert one extra “dot” length spacing between characters. Selecting 3 will insert an extra
2 “dot” lengths, and so on.
Note that auto letter spacing is ignored while in setup mode.
X
(Default:
0/9)
Cut numbers: The keyer will send Øand 9using the current setting and wait. You can cycle between
no cut numbers (Ø 9) cut zeros (T 9), cut nines (Ø N), or both (T N). Note that this only affects the
way QSO numbers are sent. Other numbers in stored messages, or numbers sent by hand, are not
affected. The default setting is no cut numbers.
Z
(Default:
N)
Leading Zeros: The keyer will send “Y” or “N” and wait. As with other menu settings, either paddle
may be used to switch between the two settings. Ywill send numbers in stored messages with up to
two leading zeros (1 is sent as 001, 99 is sent as 099, 123 is sent as 123, 1000 is sent as 1000). Nsends
numbers without leading zeros. Like the X setting, this affects only QSO numbers and not other
numbers stored in messages or sent manually. The default setting is N.
B
(Default:
15 sec.)
Beacon delay: The keyer sends the current beacon delay in seconds. Use the dash paddle to increase
or the dot paddle to decrease the delay between beacon transmissions from 0 to 99 seconds.
W
(Default:
5)
Weight: The keyer announces the current weight and waits for input. The dot paddle may be used to
decrease the weight or the dash paddle to increase it. Weight can be set anywhere from 1 (50% "light")
to 5 (normal) to 9 (50% "heavy"). The default setting is 5.
T
(Default:
Y)
Sidetone: The keyer announces the current sidetone setting and waits for input. You can use the dot
and dash paddles to switch between “N” (sidetone OFF), “Y” (sidetone ON) and “M” (MCW mode).
In MCW mode, the keying output is active any time code is being sent and for two word spaces after
the key is released. This can be used to control the PTT line of an FM transmitter. Regardless of the
sidetone setting, the sidetone is always used while in setup mode.
K
(Default:
Mode A)
Key Mode: The keyer will send the current keying mode: "A" or "B" for iambic A or B timing modes,
“U” for Ultimatic, “G” for bug or “S” for straight key. You can use the key or paddle to switch
between modes. In “Bug” mode, dots are made automatically with the correct spacing and length with
one paddle input, while dashes are made manually with the other. If straight key mode is selected while
using a paddle, either paddle input will key the transmitter.

PicoKeyer-Plus 05/25/2014 (Firmware V4.5) Page 10 of 19
P
Paddle Selection: This will allow you to reverse the paddles for mis-wired paddles or left handed
operators. Simply hit whichever paddle you want to use for DITs. No need to rewire your paddle!
A
(Default:
Around 2
kHz)
Audio Tone: The keyer will send a dash at the selected sidetone audio frequency each time a paddle is
hit. Use the paddles to increase or decrease the audio frequency as desired. The default setting is
approximately 2000 Hz, which gives the loudest audio from the on-board speaker.
D
(Default:
0)
Transmit delay compensation: Some transmitters tend to shorten Morse code elements when used in
QSK mode. This setting can be used to lengthen Morse elements and shorten spaces to compensate.
The setting can be from 0 to 50 milliseconds. This is similar to weighting, except that it is independent
of speed. Weighting shortens or lengthens elements by a percentage; delay lengthens elements by a
specified number of milliseconds. Be aware that this can cause problems when using large delays and
fast speeds. The default setting is zero.
V
Firmware version: The keyer sends the version number of its internal firmware program.
C
(Default:
PDL)
Command Mode: You can select between “Button” mode (BTN) or “Paddle” mode (PDL). In Paddle
mode, you will hear a “?” prompt once you enter setup mode. Simply use your paddle to send the
Morse letter of the option you want to review or change. For example, to set the speed you would send
“S”. To leave a menu item, tap the button to return to the “?” prompt. To leave setup mode, either tap
the button again or send “SK” with your paddle.
In Button mode, just hold the button to scroll through the list of available commands. When you hear
the letter of the item you want to change, release the button. When you’re finished with that setting,
