ICOM CI-V INFO : MEMORY STRUCTURES FOR IC-7000 AND IC-7400/IC746PRO

 

SEE ALSO THE PAGE ABOUT MY ICOM MEMORIES MANAGER SOFTWARE THAT USES THIS INFORMATION

 

The DF4OR web site has a wealth of information about the CI-V structures however it hasn’t been updated for a while and two Icom models which haven’t got full memory data documentation are the IC-7000 and the IC-7400/IC-746Pro. There seems to be a complete lack of data elsewhere on the web as well.

I have recently purchased a 7000 and spent some time looking at the CI-V command and response streams, the 7400 I have had for some years but haven't overly wondered about programing memories via the CI-V.  The structures for the memory contents is as follows...

 

The data displayed is as determined by writing/reading an actual IC-7000 at address $70…

Remarks:

The data layout is specific to the IC-7000. The second set of data (Frequency, Mode, Filter, Flags, Subtones) probably uses only the frequency when in split mode.   Use the Read command below to receive back the actual contents of any memory location.
