If You having troubles getting IC-7300 on digimodes, here's a short tutorial "how to" simply and effective.
Although it's another new family ICOM radio, they made changes in PC communication.
As You remember when using IC-7100 we were obliged to use separate Virtual COM port software to get running on 7100 on TX via CAT command. Things are slightly different in 7300, I would say they simplify the settings.
There's only need to choose right settings in TRX descibed below.
Starting with USB Driver download from ICOM's page
Remeber not to connect your TRX prior to have USB driver installed. Well, it will not kill You ;-) but can make some trubles installing USB driver properly.
After positive instalation You'll get Windows Device manager screen like this :
Of course the numbers of the port will be set depending of your PC. This is the port we will use to connect the 7300 for sending CAT commands and other things.
Now time to set some things inside TRX. Enter the MENU, SET, and choose the CONNECTORS label.
NOTE: These setting are valid, assuming You will use 7300 for digi modes work using PC. If other interfaces - we need to change other settings as well.
You can simply choose which type of Serial command line will key the TRX. We have "Data Terminal Ready" line (DTR) and "Request To Send" (RTS) lines. Choose according to your software settings.
This is it. Now the radio is ready to get PTT signals from MS/digi software.
For Meteor scatter digi modes I am using MSHV software developed by LZ2HV, and this is how the settings look like :
All we need is to set the COM port number installed previously, set the speed accordingly, and check DTR or RTS line same as TRX settings.
As You can see, LZ2HV offers direct CAT communication with TRX. Althought there's IC-7100 on the list already, it will not work with 7300. I am pretty sure that LZ2HV will expand RIG list soon.
We are done! GL with MS/digi.
