This cable set consists of four components:
  • Transmit Audio:  3.5mm stereo right-angle to straight through cable (green band)
  • Receive Audio:   3.5mm stereo right-angle to straight through cable (red band)
  • RX I/Q cable:      2.5mm right-angle to 3.5mm cable
  • ACC2 Module:    2.5mm stereo right-angle to KEY OUT and PTT IN (or Transmit Inhibit, or AuxBus) molded module. 



Q: I would like to run my KX3 for digital operation with my computer.  Is this the cable set I need to purchase?

A:  Yes.  You can purchase just the Receive and Transmit cables separately or you can purchase the whole cable set.

Q:  I want to use some of the new SDR computer programs such as HD-SDR and CW Skimmer.  What cable do I need for those applications?

A:  The RX I/Q cable adapts the RX I/Q port to a standard 3.5mm plug so that you can use the soundcard in your computer to process the signals needed for any of the new SDR programs.  You can purchase just the individual cable or the entire KX3-PXKT to obtain it.

Q:  I would like to connect my KX3 directly to a higher power linear amplifier.  What cable do I need?

A:  The ACC2 Module cable exposes the KEY OUT signal that is needed to enable a linear amplifier to go into transmit when the KX3 does.  The RCA jack you see on the module is the KEY OUT signal formatted into an RCA jack that is commonly used with my popular linear amplifiers, including those from Elecraft.  

You can purchase it separately or as part of the KX3-PCKT cable kit.
