Playing around with one of those silly but fun little "Teach your kid about electronics!!" kits from the 80s (dating myself there oh dear), which had a bunch fo components wired into a cardboard board, and you could connect connector cables between each segment's input and output to make circuits, and one was a radio. and... I picked up a numbers station on it.
I mean this is when I didn't even know what Numbers Stations were, or that they even existed. I just found this really weird, faint, kinda garbled signal that was playing odd tones and then an automated voice started saying numbers and letters in a foreign language I couldn't understand. It was...creepy but fascinating.
@lizardsquid it super was. :o I wish I'd know way back then what I was hearing and I wish I'd noted down what frequency or something and told someone else about it because I wa sjust dinking about and then got bored and super distracted and forgot clean about it until recently, and several other times sporadically throughout my life for brief moments of "oh huh that wa skinda cool"
