Do You Have a QSL Card? [I Love Radio]

@HootyTheNightOwl My dad used to send and collect them. Ham and CB radio operators often exchange them.

@GerOttman I have no idea what they even are... 🤭

@HootyTheNightOwl It's kind of like a postcard. It has places to write down the date and time, the channel or frequency, other details.
