Locked Re: No Transmit power or ALC on IC 7300 #Cat_RigControl


I found this online. I can't verify since I don't own a 7300.

Mac OS Settings

Applications->Utilities->Audio Midi Setup->USB Audio Codec 1: Left/Right both set to approximately -9.0db, adjust as needed while monitoring ALC levels on the rig. ALC should be at about 1/2 to 3/4 while transmitting. Some experimentation and outside verification (Web SDRs?) needed to make sure you're not overdriving the audio.
