What you *really* need is a mod monitor that operates off the air signal so no direct connection is necessary. It’s easy and doesn’t even use a smidgen of your power! There are several. I bought a brand new Inovonics this past year. I spent more than any sane person would do to monitor a Part 15 station, but I can also use it to monitor the commercial stations I work for AND their competition, since it’s frequency agile. Just punch up the station you want to check on.
But there are older Inovonics units for the task, as well as some others that escape my memory at the moment.
