about me

Do you have a Gremlin in your ham shack?  Want to keep the Icom PW-1 from blowing up when using a logger or contest program?   Eliminate unusual behavior of your Icom CI-V bus while under computer control?  Use a CI-V Router!

This box is an intelligent replacement for the ICOM IC CT-17.  It provides a USB interface to the PC and three isolated CI-V ports, with ICOM message store and forward between each of the total of four ports to prevent collisions.

K9JM Router

The Icom CI-V bus does not work and play well when more than two items are on the bus.  This is especially true if you connect a logging program to the bus while another piece of radio equipment is trying to 'follow' an Icom Radio.  If you are an owner of an ICOM PW-1, did you know that Icom put an errata sheet in with your amplifier that tells you not to connect your transceiver and amplifier to a computer?  Here is the document.   The CI-V Router ends collisions on the bus and acts as an intelligent interface to your host computer.  Read a detailed description on how it works.

Features:
  • High speed bi-directional USB interface to host computer.  Supports Windows, Linux, Mac.
  • Three isolated CI-V ports
  • Powers off of USB or an external power supply
  • Bypass relays disconnects router when powered down.
  • Eliminates collisions and erratic behavior of the ICOM CI-V bus

Being an Arduino based product , it is easy to customize the CI-V router to do other things in your shack!  It is trivial to make CI-V router into a band decoder to select antennas and or band filters. Some notes are available.  Full CI-V routing source code is available.  If you want to read about my own tricked out CI-V router, read this write up.

For those of you who have access to a 3D Printer.  Download this description of the custom K9JM CI-V Router box.  Picture shown below:

Keep in mind,  this is a hobby for me, it is not my day job.  If this sells beyond any reasonable expectations, I might make about five cents per hour for my time. :->

NEWS:

1.) New Beta version 1.11 Router software now available.  There are no changes to the core routing portion of the code.  There are several new configurable features.
User Guide update that details these new features

 2.) 
I now have a version of router software to operate with Acom amplifiers.  Contact K9JM for details.
