Be thankful if you DIDN'T live in England during 50's, 60's and 70's!

the LO thing worked great for me in the 80's and 90's.
used it to find a couple of new freqs in police stations.
franklin lakes nj for one.
i heard them say use your handheld. i figured someone at the HQ would want to listen to that.
so for lunch i parked in the parking lot, did some math and started to search the band.
they were on 159.09 for the regular stuff and 159.03 for the handhelds. ah the fun of hunting !
then i used it in reverse.
very late one night the wife and i were out eating in the saddlebrook diner (or whatever it was)
a young cop came in with his handheld all the way up, (most annoying)
i did some math again then looked at the wife and said "dance mailman"
that was a line from cheers and a shock collar on the mailman
i had my little pro32 scan across his radio freq and it did nothing but "thumm thump"
he apologized to the young girl at the counter and turned it down.
a few moments later it was up and i did it again. he wondered what was going on but he left and that was better.

OP, you may be interested in the following: TV detector van - Wikipedia

Also, listening to the IF of car stereos was something conjured up for advertising back in the '90s if I'm not mistaken. How it worked was say you drive at a mall and the mall had the equipment to know what station you were listing to. Now they have data for marketing... Today, marketing data is absolutely EVERYWHERE in ways you can't even fathom. In India for example there is a sub audio sound transmitted from certain TV channels or whatever and your phone would hear this and report back to data broker central to know what channel you were watching, the time, device ID, etc. In the U.S I don't think they do this, but could be wrong. The technology could be used in different ways as well.

God help you if you have an Amazon smart speaker... There was an open source alternative called Mycroft (not related to Sherlock Holmes lore) but it's been replaced by something else and I haven't kept up with the project.
