Well, I'm not going to get into this religious argument again.
I don't doubt that it's still being used outside of ham and CB. There
are still people who use cassette tapes and LP records, and they are
still being made.
And there are still tons of people using Belling-Lee plugs on PAL TV
sets, even for DVB-T. It doesn't change the fact that is completely
mismatched for a 75 ohm system.
