Hi All,

 I am trying to get my ICom 820H working under CAT. 

I have an OPC-478UC It is USB to single line CI-V required by the ICom 820H.
I have shifted it's output to the tip from the sleeve on the 1/8" phone
plug. Under System / Device hardware the OPC 478 shows up as com 3.  The
radio does not control.  I have set the address to 60h from 42h in the radio
and the baud rate to 9600 on both radio and program. I get the E/A Fehler-32
warning when I try to store the com port values. The OPC 478UC does work my
ICom D800 and when connected to the 820H will return a Com 3 when com port
is selected. If I unplug the cord to the 820H it tells me no radio is


Any help on this one would be appreciated.
