Remote 'Twin' Control of the K3 with
real knobs and buttons for a 100% real time radio feel.
The K3/0-Mini, full-size K3/0 or a standard K3 in ‘terminal mode’, provides a unique real time remote control experience for operating a K3 located in the next room, or across the country. The latest K3 firmware supports a compact remote control serial protocol that provides a 100% recreation of the remote K3 on the controlling K3. All local front panel VFO knobs, other controls and button actions are immediately reflected on the remote K3, and all display functions from the remote K3’s LCD and LED are immediately displayed on the controlling K3.
Replacing the full-size K3/0, the K3/0-Mini consists of a K3 front panel, only, so it's highly portable. The K3/0-Mini is perfect for home and travel use due to its small size. It fully duplicates all K3 controls, displays and menus for a realistic remote K3 experience.
The K3/0-Mini has other features not found on the full-size K3/0, including:
Simplified RemoteRig Interfacing
Use a single RemoteRig interface cable for connecting the RemoteRig to your K3/0 Mini. This cable contains all IO connections from the RemoteRig (SP, MIC, PTT, PAD, KEY, RXd, TXd).
Paddle, PTT and KEY inputs are now available both on the K3/0 Mini and RemoteRig. 3.5-mm audio connections on the side connect to your headset without the use of adapters.
Built-in Stereo Speakers
A pair of internal speakers powered by their own audio amplifier for stereo (main/sub RX) audio.
The requirements for K3-Remote operation vary depending on the options and methods you choose to setup or control a K3-Remote based system. The K3/0-Mini comes with everything required for interfacing to a PC via USB connection. PC based K3-Remote solutions are becoming available for use with a K3/0-Mini; such as, RemoteHams.com. The K3/0-Mini also interfaces into RemoteRig based K3-Remote systems; such as RemoteHamRadio.com. More information about RemoteRig devices can be found at the RemoteRig.com website. Please review the below items for making the proper decision in setting up your K3-Remote system.
PWR12V1A-US (External Power Supply, 12VDC 1A, US Only version)
RemoteRig based System Options
RemoteRig 1258MkIIs Set (RRIGSET) is the RemoteRig Set (both remote and control) for setting up a complete K3-Remote.
1258MkIIs Control Unit (RRIGCON) is the control unit only
used to access a RemoteRig based K3-Remote.
The RRIGCON is provided without a power supply by the manufacturer. If an external power supply is required, please add PWR12V1A-US (External Power Supply) to your order.
K3/0-Mini to K3 Remote requires RRMINICBL & RRMTCBL cable sets, unless you build your own cable set.
K3/0 to K3 Remote requires RRK0CBL & RRMTCBL cable sets, unless you build your own cable set.
K3 to K3 Remote requires RRK3CBL & RRMTCBL cable sets, unless you build your own cable set.
Note, RRMTCBL is only required when you are setting up both control and remote sites.
Both control and remote K3s must be using K3 f/w 4.48 or later for proper K3-Remote operation.
The K3/0-Mini comes with built-in USB support using the USB audio CODEC & FTDI technology.

When paired with the RemoteRig devices (also sold by Elecraft) this K3 Remote system can connect your local K3 or K3/0 to a remote K3 over the internet, including transmit and receive audio, without the need or complexity of setting up computers on each end. The K3 Remote system provides a provides a real radio feel with immediate control feedback and very fast response times. The K3/0 connects to the RemoteRig unit through its rear connectors. It uses its internal speaker and front headphone jack for receive audio, and its front microphone connector for your mic input. The result is a faithful recreation of your remote K3 on the local K3 that is hard to distinguish from operating the actual radio.

The Microbit Setup Manager Program is used to configure the network settings on the RemoteRig devices via the USB interface when you can not reach the devices over your network.
is the difference between the two RemoteRig devices available in the set?
There is a "Remote / Terminal" device which connects to the remote K3 and another "Local / Control" device that connects to a K3/0 or a "Control" K3. The "Remote / Terminal" box does not have a CW Knob on the front of it, while the "Local / Control" box has a CW Knob. See the diagrams above to overview the cable connections to each "Terminal & Control" RemoteRig devices.
kind of internet connection is required for remote operation?
It is recommended to have a minimal download and upload speed of 512 kbit/sec with low latency (less than 75ms ping). If using a high latency connection (such as mobile phone networks, 3G/4G) you may experience "chops" in the audio stream along with delays in the front panel controls. It is possible to configure the Jitter buffer delay and Audio packet size to adjust for high latency connections. The required download/upload speed may vary depending upon the settings selected on both RemoteRig devices. For example; enabling Dual-RX for stereo reception of the SUB Receiver doubles the speed requirements. It is possible to lower the "Audio Quality" in the "Radio Settings" page on the Control RemoteRig device for lowering the download and upload speed requirements. By default, Dual-RX is turned off (Stereo Mixed to Mono) and the Audio Quality is set to "3 - alaw 12 kHz".
I have to configure the RemoteRig for remote operation with my K3 and/or
Yes & No. The RemoteRig sets supplied by Elecraft are pre-programmed for K3-Remote operation over your local area network. If your only using your K3 Remote over your own local network, configuration is normally not required. When setting up your remote over the internet, you will need to configure your network settings on both RemoteRig devices and enable port forwarding in your router for 3 ports (12000,11000,5060). Refer to the K3-Remote manual for more information about port forwarding and obtaining your network information.
it possible to use a PC as the "Control" device without a
"Control" K3 or K3/0?
Yes. In most cases, you can use the RRK3CBL cable set as this setup is similar to that of a K3 to K3 remote. An external speaker is required for listening to audio or a stereo audio cable to patch audio from the SP jack on the RemoteRig device to your Microphone port on your PC. This will allow for programs (such as FLDigi) to decode digital signals. A custom Microphone / PTT cable is required for enabling PTT & TX Audio from your PC to remote K3.
I use radio control software (such as HRD) on the remote K3 while using a
K3/0 with the "Control" RemoteRig device?
Yes. For Yes. For this to work, you need to set COM1 to Mode-7 on both "Control" & "Terminal" RemoteRig devices. This will duplicate CAT over COM1. You can then connect your control software (HRD) to COM1 on the "Control" RemoteRig device and use as if you are connected to the radio locally. The control K3 or K3/0 must be on and functioning with the remote K3 for your control software (HRD) to function properly.
