Receiver for eletromagnetic radiation between 9KHz to 1000KHz

Receiver for eletromagnetic radiation between 9KHz to 1000KHz

(OP)
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.
