[Icom] CT -17 interface

Thu, 15 Aug 2002 19:25:06 -0600

In order for the PW-1 to track the current frequency the setup procedure
requires one to set "CI-V Transceive" to "ON" on the transceiver which
results in the transceiver broadcasting its current dial setting and all
other receivers and transceivers on the CI-V bus following.

In addition, the PW-1 has the REMOTE 1 and REMOTE 2 jacks wired
together.  Therefore it is not possible to have two completely
independent transceivers connected to the amplifier without inventing
some of your own switching.  Yes, the PW-1 is smart enough to follow
radio 1 when set to input 1 and radio 2 when set to input 2 but radio1
and radio2 will still be slaved to each other.  And I'd guess that if
radio 1 and radio 2 were the same type of transceiver (same default CI-V
address) that one would have to change the CI-V address on one of them.

And no, all four radios cannot have the same address.  The outcome is
that is very unpredictable.

The Accessory connection is used primarily for ALC, T/R and the like.  I
don't believe that the amp uses the band information available there.

Hello Ekki,

I am surprised at your problem. My understanding of the Icom interface
doesn't
explain your situation. Apparently I don't understand the interface.

When I read the Icom radio instruction books, the radios do not
broadcast their
frequencies without a request from a computer. When such a request is
made, only
the radio that the request is addressed to would respond with its VFO
frequency.

Is it possible that your computer when reading a new frequency, commands
the VFO
to the frequency just received?? Secondly is it possible for all four
radios to
have the same radio address??

I'll admit I am confused. Could somebody explain??
