I'm starting to see where Klaus got his Heterodyne shows reputation.........

Any that include heterodyne 🦇 sounds rank well in my view
It’s great Steve continues to find space for us to hear bats

hell yes!!! top 10 instrument for me, eclipsed only by the ondes martenot (which has a similar sound in the original models because of heterodyne synthesis)

I understand completely, heteodyne is extremely useful but it is not the sound of bats, it's something else completely. And personally I seldom use heterodyne detection for real-time alerts, I am pretty much always in time expanded mode and invariably I hear a bat before the heterodyners on a walk.

The heterodyne alerts the user to the presence of bats in real time, it is a notification to look about and see a bat that might otherwise be missed. And of course we get the wonderful feeding raspberry in synchronisation with the action.

For those of you who have been led to believe that your heterodyne detector's bangs, cracks, slaps and warbles are representative of bat vocalisation - sorry (not sorry) to disappoint. Bats sing. They don't beatbox. Very different things.

[December 12th, 1925] Advertisement: The advertisement lists three Radiola radio models: Model 102 ($140) with a Uni-Rectron for AC power; Model 28 ($260) with super-heterodyne tuning and battery or AC operation; and Model 20 ($102.50–$115) with regeneration and dry batteries.

Public information announcement. Bats don't sound like Keith Moon, firework displays, machine guns, Geiger counters, crackling fires or warbling aliens.

That would be heterodyne bat detectors.

Bats sound like birds.

Letting conspiracy-brained weirdos gather together and heterodyne on the internet was a bad idea.
