Hello: I finally finished the homebrew Max232 interface. I want to use two IC706MkIIg's for SAT contacts. It says in the 706 manual that the CI-V address for the 706 is 4EH, with choices of 01H to 7FH for other address choices. When I go into SATPC32 for setup the Radio, it does not give me choices in the radio addresses that include the 706 addresses above? Do I set the program for any recommended program Icom address, such as $4A, B
or
C and the radio CI-V address to any of their recommended address choices. The radio address and the program address will be different. Will they communicate with each other having different addresses on each end? Please advise, thanks, trying to get all this running by Field Day, June 23.
I am still using the demo version (unregistered) of the program with
updated keps.
Also, I want to use a Dell inspiron 4000 Laptop for the PC and it is
stated in
the SATPC32 instructions for using Icom that usually with a laptop I will
need to use a USB to
Serial Adapter. If the laptop has a serial DB-9 connector on the back and
it
says in the system info that it has a Com1 port, which I assume is the
DB-9
that is labeled for serial port, will it work? How will I be able to tell
if the port will work with the interface?
I appreciate any advice, much thanks and 73, Robert Lasso W6RQR

Hello Robert, to steer 2 IC-706MKII radios you need an Icom CT-17 or compatible
interface
for level conversion RS-232 <> TTL. Such interface can easily be built
for
about $10 .. $12.
I attach a file with the schematic diagram of the interface I'm using
for
several years with my Icom 821H and IC-910H. Also, I attach an
instruction
text for Icom users that comes with my software SatPC32. It describes
how
to
connect the Icom radios to the PC. Note, that the pin numbering on the
PC
side in the diagram refers to a 25-pin DB connector. With a 9-pin
connector
the pin numbering is different (described in the text file).
The interface can also be used to steer two radios. Both radios can be connected parallel to the interface. So, you only need a second jacket
on
the radio side.The Icom CT-17 does the same (4 connectors parallel).
With SatPC32 you can steer both radios for full duplex satellite
operation.
As you will know the Icom radios can be accessed by their device
addresses.
So, you only need to change the default device address of one of the IC-706MKII at the radio and accordingly in the program. The program will then steer one radio for RX, the other for TX. Whith SSB satellites you
can
tune the RX radio around the passband and the program will then automatically tune the TX on the correct uplink frequency.
If you want to test the program you can download the demo version from
my
website www.dk1tb.de , English page "Downloads". The demo is fully functioning. The only restriction: the users geogr. coordinates must be entered at each program start. But for CAT steering tests even that is
not
necessary.
73s and best wishes for 2007
