Historical receiver?

[keithpeter]

I’m wondering what kind of receivers were in use to receive traffic at (or near) Grimeton in 1924.

Would they still be regenerative detector receivers or would superhets with BFOs be in use by then?

PS: best wishes for the future and thanks to all the volunteers.

Hello

Wiring diagram of the “synchronous detector” at the receiving station for SAQ?

Same question on your forum there so delete this thread if you want to keep things focused.
