Agree with you there, tho Crystal sets with a decent antenna will still be able to pick up SW radio from around the world.
Best I've done is Radio Göteborg (Sweden) with a simple diode crystal set, no amps, no batteries

R.I.P. Superheterodyne receiver, you served us well
Nah, the new digital technology still relies heavily on superhet design, just the modulation technique has changed.... a lot.
Even the mobile in your pocket is a superhet

Is it just us or were crystal sets a real traditional, old fashioned boys pastime? Along with making rockets and catching tadpoles?

Yeah, I understand about the superhet, it's still there but fixing old radios, particularly valves and early transistor types will never be the same, will it.
