The picture towards the end of the antenna in the window is funny, since I personally would be afraid someone would panic seeing it set up.

Don’t like the thought of explaining a radio experiment to a flight attendant at 30,000 feet!

I did raise eyebrows once of the person in the row behind me. I said I was listening to ATC and that seemed to placate him. I do believe most airlines have a blanket ban on radio equipment, even receive only. Some even ban using GPS!

Some are even banning AirTags to cover up the shit job they’re doing with luggage.

I've been travelling a lot the last 6 months and have really wanted to try out my SDR on the plane, but it looks so sketchy.

Many, many, many years ago (before 9/11 and before cell phones were commonplace) I used to carry my ham radio HT and call on simplex (146.52 for those that know) and make contacts. Those were fun times.
