Greetings,
I'm new to electronics and am interested in the field just as a hobbyist. I've read the Complete electronics self teaching guide by Boysen and Kybett and am now moving to Basic Antennas ARRL and Building your own transistor radios by R. Quan. To be honest im attracted to RF technologies and once I can get a handle on building my own radios I would like to get my ham licence.
I decided to document this project here as I would have many questions along the way and one thread should suffice in asking all questions.
So to begin, this circuit below, should I be picking up modulated AM signals on the oscilloscope? I believe I have constructed a bandpass filter operating as an antenna tuner:
I constructed this circuit so I could detect AM signals on the oscilloscope, in an effort to understand how to construct (bias) the amplifer for the next stage. Unfortunately all i'm receiving is noise on the output. R1 is grounded to the oscilloscope, C1 is a variable capacitor and L1 and C1 are tuned around 1kHz. This frequency is the centre of our AM broadcast band - Sydney, Aus.
Any advice would be appreciated.
