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.
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.
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
Provides ICOM ® address translation between ports.

Currently selling in two forms, a full up router, assembled
and tested for $160 or just the CI-V Router board assembled and
tested for $50, the user can source the other elements. For
details read the User Guide. Standard shipping is USPS
Priority Mail Small Box with delivery confirmation ($6.55).
International orders: Contactme.
Do NOT order with the "Buy Now" below. Only CI-V
interface boards are shipped internationally, and shipping costs
vary with county. International payment is best done through
Thirty day unconditional warranty, if you are unhappy for any
reason, send everything without modifications back and get your
money back. Arduino warranty applies to the Arduino board.
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. :->
1.) Icom released new firmware in May 2015 for their 7600 and
7800/785X radios. These radios now supports two commands
(0x25 and 0x26) for directly reading the main and sub
receiver frequency, mode and bandwidth. There
are at least three software packages that supports these new
commands, N1MM+, Ham Radio Deluxe and DX
Commander. More are being added daily. The router
software versions 1.11 and earlier assumes that these new commands
are invalid and will not forward them. Using the new Icom
firmware with new versions of PC software which supports these new
commands will not work with old version of the K9JM router
software. Please update router firmware to version
1.13. Software download
2.) Version 1.11 Router added new features. There
are no changes to the core routing portion of the code.
There are several new configurable features. There
June 2015 User Guide covers these changes.
Ability to establish a power table, to control
radio drive power to the amplifier as a function of
Test routine to test the interface board and Arduino
Ability to send a SPLIT OFF / SUB OFF command to the
radio when QSY > 1MHz to unwind split operation when
Ability to do ICOM ® Address
translation. So that multiple controllers can be
connected to the router at a time. This is done to
support non-ICOM ® amplifiers, such as the Acom,
and Microham products.

I would like to thank Sir James Abraham, W6EB, for beta testing
and providing constant feedback and the loan of a second Icom XCVR
for testing. Also thank Bill N3RR and Dennis K6DEN for
their testing the Acom interface.
Units are available for loan to DXpeditions for credit upon
