The K3/Ø-Mini is a Remote Control Head for the K3 Transceiver  at Dayton Hamvention 2013

–  Two RemoteRig RRC-1258MkII (picture below) units that provide the interface to the internet; one for the remote location and one for the local (control) location

– RRMTCBL cable set to connect the remote RRC-1258 unit to the remote K3.
– K3/Ø Remote control Head (Test at Dayton Hamvention 2013 )
– RRK0CBL cable set to connect a local K3/0 as the controller.
– RRK3CBL cable set to connect a local K3 as the controller.


When paired with the RemoteRig internet control system (also sold by Elecraft®) this K3 Remote system can connect your local K3 or K3/Ø 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 real radio feel with immediate control feedback and very fast response times.

The K3/Ø, or a regular a 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. – [Note] The latest K3 firmware supports a compact remote control serial protocol – (Source Elecraft ® website)

KAT500 Auto-Tuner & Smart Antenna Switch – (Source Elecraft ®)

The new KAT500 uses the same topology and performance tuning algorithms as the 100W autotuner in the K3. Typical matching range at 500 W is up to 10:1 on most bands.

Frequency Typical Matching Range and Power Limit:
1.8 — 2MHz 600W into 10 to 500 Ohms (5:1 Low Impedance, 10:1 High Impedance SWR) / 3 — 30 MHz 600W into 5 to 500 Ohms (10:1 SWR) / 1000W into 16 to 150 Ohms (3:1 SWR ) / 1000W into 16 to 150 Ohms (3:1 SWR ) and  30 — 60MHz 500W into 5:1 SWR (10 to 250 Ohms)
The KAT500 measures transmit frequency to automatically select tuning memories and antennas – The KAT500 can tune with 10 W but we recommend 20 W to 100 W for best tuning accuracy – The KAT500 has a front panel SWR display and three selectable antenna outputs.  –
