Absolutely. You would need an antenna connected to an audio transducer (speaker or 'phones) to hear it. (Perhaps one would call it a non-conversion receiver.)
An audio amplifier helps, but you have to deal with the 120 Hz buzz caused by the 60 Hz power line fields all around. A high pass filter with a cutoff above 150 Hz helps a great deal. Listening to the variety of squeaks, chirps and other noises produced by electronic discharges all over the planet is a fascinating hobby in itself. They are commonly referred to as 'Sferics, short for atmospherics. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of thelastdb Sent: Thursday, March 23, 2017 6:57 AM To: Ken G Kopp; wa9fvp; elecraft@mailman.qth.net Subject: Re: [Elecraft] K3S ELF 10KHz Wait a second, there's a big difference between a sound pressure wave and an electromagnetic wave at 10-kHz...
