First off, apologies for being "technically stupid".

I have been using G-IP for a few years now to mostly download radio. I have attempted several times to improve the quality of the radio recordings and note the instructions in the FAQs, but cannot work out where I should input the command "--radiomode=good"

I have put this into G-IP and into the Command Line, but both are invalid. A simple question, but where do I input this command to, please?
