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.

CI-V Router in Arduino Project Box

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.

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. :->
