Receiver for eletromagnetic radiation between 9KHz to 1000KHz

Receiver for eletromagnetic radiation between 9KHz to 1000KHz

Receiver for eletromagnetic radiation between 9KHz to 1000KHz

Hello all

My Name is Nuno and this is my first post

I need to make a simple receiver to measure eletromagnetic radiation from light lamps. I need to measure between the frequency range of 9Khz to 1000KHz.
I tried to conect to a spectreum analyser a simple radio am antena with a smal amplifiyng circuit, however i detetct nothing. I think is becuase the frequency range is very low.

Can any one give some advice

Thank you

RE: Receiver for eletromagnetic radiation between 9KHz to 1000KHz

There are a lot of people that experiment at these frequencies, and amplifier and receiver circuits available. Do a google search for VLF and LF receiver circuits. Antennas at this frequency may be designed to be sensitive to the E-field as in a wire antenna, or to the M-field as in a ferrite rod antenna.
