The features of the IC-970 are most similar to the IC-820 and the IC-821. I
used the operator's manuals to compare the CI-V command support for each
radio. The CI-V commands for the two radios are the same, EXCEPT for the
"Main Band Access" and "Sub Band Access"commands.
For some strange reason, these two CI-V commands are reversed in the IC-820,
compared to the IC-821, IC-910, and the IC-970. Therefore, as far as CI-V
commands, the IC-821 is most similar to the IC-970.
My IC-970H CI-V is set at the default address of "2E", 9600 bd. and
"transceive mode" is set to "on".
I tried changing the transceive mode to "off" and "on" once the program
began working correctly. It does not make any difference whether it is set
to off" or "on" with my IC-970.
SatPC32 "Options" settings are: IC-821, address of "$2E" and 9600 bd.
The "SatSetup" program in SatPC32 must have the "CAT Delay" set correctly
for your radio. I tried several different settings, but "70" provides the
best operation with my IC-970H.
My WinXP com port settings are the standard "8", "N", & "1", with no
handshaking.
