Re: Commander loses CAT link to rig
Great! Making progress...toggle quoted messageShow quoted text
Totally redid ground system -- bigger and shorter wires. Also set all the USB ports to not power down. Added ferrite choke at each end of USB cable between IC-7300 and computer.
Operated almost a full day until I got the following:
Error in Sound Input
An error opening the audio input device has occurred.
Checked all the settings for audio and nothing changed. Had to restart Commander and everything good again.
Still RFI, or is there something else in Commander I need to change?
