Introduction

The K-Pod control panel is an ideal companion to your Elecraft K4 or K3 transceiver, maximizing convenience and operating efficiency. It’s small enough to be placed anywhere the action is, typically next to a computer keyboard. It’s versatile enough to integrate multiple transceiver and station control functions.
Features include:

• A heavy, free-spinning knob that can be assigned to VFO A, VFO B, or RIT/XIT offset.
• Control of 16 functions using tap and hold operation of 8 programmable switches.
• On a K4, switch functions can be set up using the radio’s built-in macro editor. On a K3, the K3 Utility The PC software applications can be used. In either case, simple or complex functions may be performed, such as selecting bands, modes, frequencies, or power levels;  sending messages; clearing RIT; changing tuning rates, etc. Examples are provided in this manual. Additional capabilities will be provided with future firmware releases,  such as direct control of the unit’s three general-purpose relay drive outputs.

Installation
Placing the K-Pod
The K-Pod module may be operated in any position. A built-in tilt stand may be deployed by loosening the two thumbscrews to hold it at a convenient angle (see image on page  1). In addition, two threaded holes for 8-32 screws are provided for mounting it on a user-supplied bracket or support.

Adjusting the Knob Drag
Friction to limit the ease with which the knob turns is provided by two felt washers between the knob and the K-Pod panel, just as is done on K4 and K3 weighted knobs.
To adjust the friction, remove the finger grip to access the set screw holding the knob on the encoder shaft. Place your thumbs on the center of the knob and pull forward on the edge of the grip to slide it off of the knob. Avoid using tools since they can scratch the knob finish.
Use the supplied Allen wrench to loosen the set screw and position the knob for the desired friction. A popular technique is to loosen the knob, lay the K-Pod flat on the desk,  and then tighten the set screw. This allows the amount of friction to be determined by the weight of the knob. Then, if further adjustment is desired, loosen the set screw again and either press the knob toward the panel to increase the friction or move it slightly away to reduce the friction.

Data Connection
K4 Transceiver
Connect the supplied K4/computer USB cable between the USB-B connector on the K-Pod and one of the K4’s three USB-A connectors. The radio will power the K-Pod via this cable, eliminating the need to provide power to the K-Pod’s 12-15 VDC connector. A longer USB cable may be substituted if desired.
K3 Transceiver
Connect the supplied data cable between the RADIO connector on the K-Pod and the data connector on your K3. The K3 data connector is on the bottom of the K3 near the front panel as shown in Figure 2. If you need a data cable length different from the 30” (76 cm) supplied, you can make your own as shown on page 19.
The data connector on a  K3S serial number 10787 (kit) or 10801 (factory assembled) or later will power the K-Pod through the data cable, eliminating the need for providing power to the 12-15 VDC  connector. Earlier K3S transceivers or any K3 can be modified to power the K-Pod through the data connector by changing one resistor inside the K3/ K3S. This is a simple mod that you can do yourself if you are equipped with a suitable soldering iron (see Appendix A on page 16), or you can have Elecraft do it for you (see Customer Service and Support on page 15).

Optional Power Connection (K3 Only)

If you are not powering the K-Pod through the data or USB connector (see above), connect a 9-15 Vdc power supply to the optional dc power connector shown in Figure 1.  The K-Pod requires about 50 mA. This power can be taken from the switched 12VDC OUT connector on the K3 rear panel. If you are powering other equipment such as a P3  Panadapter you can use a Y-cable to power both providing you do not exceed the current limit shown next to the connector. Some older K3 transceivers are limited to a  maximum of 0.5A from this connector and will be labeled that way. A modification kit to increase the current limit to 1A is available, order the K312VMDKT, or you can have Elecraft do it for you (see Customer Service and Support on page 15).
Also, you can power the K-Pod from any 9-15 Vdc power supply capable of providing 50 mA.

USB Interface
The USB interface is used with a K4 transceiver, as well as to update the K-Pod’s firmware. For the latter purpose, it may be connected to any USB-A connector on a PC. For further details, see Firmware Upgrades, page 14.

Auxiliary Outputs
A 3.5 mm tip-ring-ring-shield (TRRS) connector provides three programmable outputs to control external devices. Each open-drain output can handle up to 50 Vdc at 100 mA.
Controls and Indicators

Operating the K-Pod
Feedback Tone
An annunciator in the K-Pod produces a brief audible tone whenever switches F1 through F8 are pressed. In addition, changing the position of the rocker switch produces a brief tone as follows:

Controlling a K4 or K3 Transceiver from the K-Pod

Firmware updates may be required:
To use the K-Pod with a K3, the transceiver must be equipped with firmware version 5.54 or later and the K-Pod must be equipped with firmware version 1.06 or later. Refer to the K3 owner’s manual for firmware version check and update instructions.
To use the K-Pod with a K4, the K-Pod must be equipped with firmware version 1.09 or later.
Version 1.12 or later is strongly recommended.
See Firmware Upgrades on page 14 for instructions on updating your K-Pod firmware.

K-Pod Tuning Knob Functions
Connecting the K-Pod to the K3 or K4 immediately gives you control over the VFOs and OFS (RIT/XIT)controls depending upon the position of the rocker switch. Also, by default K-Pod LEDs D1-D3 indicate
the control selected: D1 for VFO A, D2 for VFO B, and D3 for RIT/XIT (OFS). These can be reprogrammed.

When using the K-Pod with a K4, you can configure the K-Pod encoder to use the same number of counts per turn as the VFO A/VFO B/OFS encoders on the transceiver. Use MENU:
VFO Counts Per Turn to select the desired setting.

Using Switch Functions

Other transceiver functions may be controlled by K-Pod switches. When pressed (tap or hold), these activate macros (strings of one or more transceiver control commands)  stored in the K3 or K4 transceiver as described below. Macros are simple to create and store. If you’re not familiar with the process, please refer to the instructions in Appendix C (page 20). Some popular macros are provided below.
K-Pod switch functions are mapped to K4 and K3 macros as follows:

• Holding switches F1 through F8 (pressing for 1/2 second or more) launches K4 macros 1H through 8H, or K3 macros 1 through 8.
• Tapping switches F1 through F8 (pressing for less than 1/2 second) launches K4 macros 1T through 8T, or K3 macros 9 through 16.

Setting Up K-Pod Switch Functions – K4
The K4’s built-in macro editor is used to both create custom functions and assign them to switches on the K-Pod. In the macro editor these are identified as K-pod.1T (switch 1 tap) through K-pod.8H (switch 8 hold).

To launch the macro editor at the K4, tap Fn in the bottom row of LCD touch controls, then hold MACROS.
Use VFO A to scroll to the desired K-Pod switch, as identified in column 1 in the LCD window. Tap on the label field (column 2) to assign a label to your macro (for reference).  Then tap on the macro field to enter one or more control commands. See examples below and more detailed instructions in Appendix C.

Setting Up K-Pod Switch Functions – K3
Store the macros you wish to launch from the K-Pod in memory locations 1 through 16 on your K3S/K3 using the K3 Utility program as follows:

• Be sure you have K3 Utility Program rev. 1.16.3.11 or later installed on your personal computer (older versions will not allow you to store macros 9-16).
• Connect your K3S or K3 to your personal computer and run the K3 Utility Program.
• Click on the Command Tester/K3 Macros tab.
• In the window that pops up, click on the Edit Macros button
• Enter the macros and macro labels in the spaces provided. Note that your macro label cannot exceed seven characters including spaces. See sample macros below and in Appendix C.
• Click on Write to K3 to store the macros in the K3.

Sample Macros

The following sample macros are divided into groups popular for contesting, chasing DX, and operating a DXpedition station in CW or SSB modes. In addition, are sample macros for RTTY and PSK operation, general macros that are useful in any operating environment, and several K4-specific macros.
To use them, create and assign the desired macros as described above. (Further details on creating macros can be found in Appendix C.) The suggested macro label may be changed as long as you observe the seven-character limit. The Command Sequence lists the commands included in each macro in the order they execute.

Every command used in a macro must be terminated with a semicolon (;)

Controlling K-Pod LEDs and Auxiliary Outputs

Commands are provided to control the K-Pod’s LEDs, as well the Auxiliary Outputs at its AUX OUT connector. These commands can be added to the macros stored in the transceiver. The transceiver stores the state of all KPod LEDs and Auxiliary outputs so they are restored to their last condition after a power off/on cycle. So you need not send them again once set, although you may include them in your macros to be resent to ensure the LEDs or auxiliary outputs are in the desired state.

When testing these commands by executing them directly in the K3 Utility Program Command Tester/K3 Macros window, a delay of up to 2 seconds may occur before the change is reflected at the iPod, instead of the about 200 ms normally experienced when the command is part of a macro executed by pressing a switch at the K-Pod.
Place these commands at the beginning of a macro string to be sure they are acted upon even if the K4 or K3 is performing a lengthy operation such as a band change.

Controlling K-Pod LEDs
By default, LEDs 1, 2, and 3 indicate the rocker switch position (VFO A, VFO B, or RIT/XIT, respectively). By contrast, LED 4 is always under user control. The following commands are used:
KPLED4ON; turns LED 4 on
KPLED4OFF; turns led 4 off

The command KPLEDROFF; overrides control of LEDs 1, 2, and 3 so you can assign them to other uses as with LED 4. Note that you can place all three LEDs under your control, or leave all three controlled by the rocker switch; you cannot reassign only one or two of them.
Once you have overridden rocker switch control of the LEDs with KPLEDROFF; you can control LEDs 1 through 3 with the commands KPLEDnON; and KPLEDnOFF; where n is the number of the LED 1, 2, or 3.
Use the command KPLEDRON; to resume rocker switch control over LEDs 1, 2, and 3.

Controlling K-Pod Auxiliary Outputs

Three auxiliary outputs are available at the tip and ring connections on the K-Pod AUX OUT connector referenced to the shield (ground). Each output can handle up to 50 Vdc and sink up to 100 mA.
Output 1 is the tip connection, output 2 is the first ring behind the tip, and Output 3 is the second ring. Each output is controlled independently
In the off state, each output is a high impedance (open-drain) circuit. When turned on each output is a closure to the ground that can be used to activate a relay, etc.
To turn an output on, use the command KPOUTnON; where n is the output number 1, 2 or 3.
To turn the output off, use the command KPOUTnOFF; where n is the output number 1, 2 or 3.

Examples

1. Control an external device such as an external antenna switch, amplifier, transverter, etc. with Auxiliary Output 1 and have a K-Pod LED light when it is on.
   Turn on the external device with Auxiliary Output 1 and light LED 4 by tapping F1 on the K-Pod: KPOUT1ON; KPLED4ON;
   Turn off the external device and LED 4 by holding F1 on the K-Pod: KPOUT1OFF; KPLED4OFF;
   Unlike LED 4 (above), using LEDs 1, 2, or 3 requires that you shut off control of the rocker switch of those LEDs. The associated macros would be: KPOUT1ON; KPLEDROFF; KPLEDnON; and KPOOUTOFF; KPLEDnOFF;
   where n is 1 through 3 corresponding to D1 through D3 on the K-Pod.
   To restore normal operation of LEDs D1 through D3 with the rocker switch, send KPLEDRON;

2. Turn the K4/K3 RIT function on and off at the K-Pod and have LED D4 on when RIT is active.
   The process is identical to Example 1 except that, instead of a command to turn an Auxiliary Output on and off, you use a command to activate RIT. Turn RIT and LED 4  on RT1; KPLED4ON; Turn RIT and LED 4 off RT0; KPLED4OFF;

You can put both commands on the same K-Pod switch (one tap, one hold) and use other LEDs as described in Example 1.
Any function you control at the K4/K3 can be associated with an LED in the same way. Also, you can combine functions, controlling a function at the K4/K3 and a K-Pod output, such as KPOUT1ON; RIT1; KPLED4ON; to turn on RIT at the K4/K3 and activate Auxiliary Output 1. Similarly: KPOUT1OFF; RIT0; KPLED4OFF;

will turn on RIT and turn Auxiliary Output 1 off.

Using the K-Pod with PC Software Applications

When a K-Pod is connected to a computer via the USB interface, the computer will recognize it as a human interface device such as a keyboard or mouse. This may be useful for many applications both in amateur radio and beyond.
Software applications that use the K-Pod may require modification in order to access the K-Pod’s knob, switches, etc. If you are a software developer, please contact Elecraft directly for details.

Firmware Upgrades

New features and improvements are available to K-Pod owners via firmware upgrades as they become available.
To obtain our free firmware download application, K-Pod Utility, visit this web page: https://elecraft.com/pages/k-pod-remote-control-module-firmware- and-utility

Connecting the K-Pod To your Computer

Be sure you have the K-Pod Utility program installed on your computer, but do not run the Utility Program until instructed to do so.

Figure 3. Connecting the K-Pod to Your Computer to Update Firmware.

When you insert the USB connector the green ON LED should light and LED D4 should blink (see Figure 4). D4 may blink slowly at first until your computer recognizes the  K-Pod, then D4 will start blinking rapidly. The K-Pod is now ready to receive firmware. If D4 is on but not blinking, you did not have both the F1 and F4 switches depressed when you plugged in the USB cable.
Start the K-Pod Utility program on your computer. On the main screen near the center is Installed in K-Pod giving you the version of the firmware currently installed and under Available the version of any new firmware.
To update your firmware, click on Copy New Files from Elecraft. When the download is complete, click on Send New Firmware to K-Pod to update the K-Pod. When the download is complete, you can reconnect the K-Pod to your K4 or K3 transceiver.

Appendix A: Modifying Earlier K3S/K3 Transceivers to Power the K-Pod via the Data Connector
The data connector on a K3S serial number 10787 (kit) or 10801 (factory assembled) or earlier cannot power the K-Pod through the data cable. This mod describes a simple change that will allow you to power the K-Pod through the data cable instead of using the separate dc power cable. The modification involves soldering a resistor onto your K3  or K3S front panel board. If you would like Elecraft to install this modification for you, contact Elecraft technical support at support@elecraft.com or call 831-763-4211.

Parts and Tools Required
Two resistors are supplied with the kit so you can install the type that is easiest for you:
Use only one of these resistors as described in the following procedure.

Description

|

Elecraft Part Number

---|---
6.8 Ohm, 1/10 W SMD (0603 sizes).| E850755
6.8 Ohm, 1/8 W Leaded Resistor

You will need the following tools:

1. A temperature-controlled ESD-Safe soldering station and fine solder.
2.  #0 and #1 size Phillips screwdrivers. To avoid damaging screws and nuts, do not use a power screwdriver. Use the screwdriver that best fits the screw in each step.
3.  Blade screwdriver (see Figure 7).
4. Diagonal cutters.
5. Fine-tipped needle-nose pliers or tweezers are handy for positioning small parts, especially the SMD

Procedure
Removing the K3 or K3S Front Panel Assembly
A grounded wrist strap and ESD dissipating mat are recommended whenever you work inside your K3 or K3S. Optionally, touch bare metal ground frequently while working.
**** Disconnect power and all cables from your K3.

**** Remove the three screws on the top lip of the front panel (see Figure 5)

Figure 5. Removing the Top Front Panel Screws.

**** Turn the K3/K3S over and remove the two screws on the bottom shown in Figure 6

**** Be sure all five screws have been removed, and then pry the front panel loose as shown in Figure 7. There are four multi-pin connectors between the front panel assembly and the main chassis. Work carefully, loosening one end a bit and then the other.

Installing the Modification and Reassembling the Transceiver
**** Install either the leaded resistor or the SMD resistor across R82 on the back of the front panel assembly as shown in Figure 8. If installing the leaded resistor, position it as shown to avoid it interfering with the main RF board when you reassemble the K3/K3S.
The existing resistor R82 is a 10k ohm resistor. The new resistor is 6.8 ohms, so it can be placed across the 10k ohm resistor with no impact on performance. However, if you have de-soldering tools and wish to do so, you can remove the existing R82 and replace it with the 6.8-ohm resistor supplied.

INSTALL ONLY ONE RESISTOR

Figure 8. Installing Resistor Across R82.

Inspect the installation carefully for solder bridges and, if the leaded resistor is used, to ensure the leads are not shorted to any nearby pads.
Replace the front panel assembly. Be sure the two bottom connectors are aligned correctly before you press the front panel in place, and then replace all five screws. Note that the two round (pan) head screws go on the bottom and the three flat head screws go on the top.
That completes the modification.

Appendix B: Data Cable Wiring

You can make your own K3 to K-Pod data cable if you need one with a different length than the cable supplied.
The cable uses two 6P6C modular male connectors and requires 5 conductors.
Do not use a common RJ12 cable unless you modify it to disconnect the wire to pin 1. If you disconnect the wire at only one end, be sure that end is plugged into your K3.

The connectors are wired pin-to-pin from one connector to the other as shown below:

Appendix C: Macro Basics

A macro (short for “macro instruction”) consists of a string of one or more transceiver remote-control commands, each terminated in a semicolon (;). These commands are normally sent from PC software applications such as HRD or N1MM, both to control the radio and determine its settings. However, remote control commands – in the form of macros – can also be used to customize switch functions at the radio itself, as well as those of the K-Pod.
This appendix provides an introduction to creating macros. There are two sections, one for the K4, and one for the K3.

Using K4 Macros
The K4 provides a built-in macro editor application to create macros and assign them to K4 user-programmable switches or to the switches on the K-Pod.
As an example, here’s how to use the macro editor to create a macro that sets the span of the panadapter to 50 kHz and assigns it to K-Pod switch F1/Tap:

• enter the K4’s macro editor by tapping Fn, then holding the button labeled MACROS
• use VFO A to scroll to the entry for K-pod. 1T (identified in column 1 of the macro editor window)
• tap on the label field (column 2), then enter the label SPAN 50 using the on-screen keyboard
• exit the keyboard by tapping ENTER
• tap on the macro text field, then enter #spn50; Semicolon (;) must be included
•  exit the keyboard by tapping ENTER
• exit the macro editor by tapping the curved arrow button

Note: In this case of K-Pod switches, the label you provide is for reference only, and appears only in the macro editor. If instead, you assign a macro to one of the K4’s user-programmable LCD button functions (F1…F8), then the label will replace the F1…F8 button label on the LCD. These are visible during normal operation whenever you tap Fn.

Other K4 Control Commands
A number of sample macros are provided in this manual, starting on page 7. These are made up of some of the most commonly used K4 and K3 remote control commands.  Table 2 in the next section also lists some commands that pertain to both the K3 and K4.
Many additional commands are available, each described in detail in the K4 Programmer’s Reference, which is available via the Elecraft manuals page:
https://elecraft.com/pages/manuals-downloads

The K4 remote control command set is, in general, a superset of K3 commands. However, there are exceptions, most notably in the switch emulation commands. These are addressed in the K4 Programmer’s Reference.

Using K3 Macros

K3 macros may be created and tested using the K3 Utility program. To become familiar with macros on the K3, do the following:

• Connect your K3 to a personal computer and launch the K3 Utility Program. Be sure it is Version 1.16.6.25 or newer 1. The version is shown at the top of the Utility program screen.
• With your K3 turned on and communicating with the Utility program, note which band is selected at the K3. It can be any band.
• At the Utility, program click on the Command Tester/K3 Macros tab.
• In the text space near the top of the screen that opens, type: SWT09
• Now add a semicolon after the 9, and watch what your K3 does. If you entered it correctly your K3 just changed bands.

That is an example of a simple macro with just one command. You can make up longer macros by entering a string of commands. You must enter a semicolon after each command to execute it before going on to the next command. The commands must be entered in the order you want them executed at your K3. The macros are stored in K3  memory and executed from the K-Pod as described under Controlling the K3 from the K-Pod (page 6).

K3 Switch Emulation Commands

You can simulate tapping or holding any switch on the K3 front panel using SWT (tap) and SWH (hold) commands. For example, the command SWT26; alternates between  ANT 1 and 2 as if you had tapped the ANT switch. Table 1 lists identifiers for all front panel switches, including those actuated by pressing on the multi-function encoder knobs. Column “nn” shows the identifier for each switch.

K3 Knob Function Control Commands

The knob on the K-Pod can only control the VFO A, VFO B, and OFS (RIT/XIT) K3 knob functions. The K3’s remaining knob functions can be controlled using commands  shown in Table 2. (Note: The K4 also recognizes the commands in Table 2.)

| MACRO FORMAT|

NOTES

---|---|---
SHIFT| ISnnnn| nnnn is the AF center frequency in Hz. There must be a space before the frequency (i.e., in the location marked ).
WIDTH| BWnnnn| nnnn is bandwidth in 10 Hz steps: 0000 to 9999 but maybe range limited depending upon operating mode
SPEED| Kenny| Keyer speed: nnn = 008 (8 wpm) to 050 (50 wpm)
MIC| Mann| Microphone Gain: 000 (lowest gain) to 060 (maximum gain).
CMP| Conan| Speech Compression: 000 no compression to 040 I
PWR| Penn| 000 to 012 (W) if no KPA3 is enabled Power (Requested)   000 to 110 (W) if KPA3 enabled 000  to 150 (.01-1.50 mW) on transverter bands with low- level output enabled
MON| Mann| Monitor Level: 000 (no output) to 060 (maximum)
AF| Anne| Main receiver audio gain: 000 (minimum) to 255 (maximum)
SUB| AG$nnn| Sub receiver audio gain: 000 (minimum) to 255 (maximum)
RF/SQL| RGnnn| Main receiver RF gain: 000 (min gain/-60 dB attenuation) to 250 (max gain, 2 dB attenuation).
SQnnn| The main receiver squelches levels: from 000 to 029 (see note below).
SQ$nnn| Sub receiver squelch level: 000 to 029 (see note below).
SUB| RG$nnn| Sub receiver RF gain: 000 (min gain/-60 dB attenuation) to 250 (max gain, 2 dB attenuation).

Note: Squelch control behavior depends upon K3S/K3 configuration menu settings. If CONFIG: SQ MAIN is set to a numeric value (000 to 029), then SQnnn applies to the main receiver and SQ$nnn applies to the sub receiver. If CONFIG: SQ MAIN is set to = SUB POT, an SQnnn or SQ$nnn command will apply to both receivers and a sub receiver RF gain command (RG$nnn) will control both receivers as well.

Other K3 Control Commands
Many additional K3 remote control commands are available, providing full access to menu settings, contents of the VFO displays, etc. Please refer to the K3S/K3/KX3/KX2 programmer’s reference, at: https://elecraft.com/pages/manuals-downloads
