    Dear Members I am designing an FM Commercial Radio but am having trouble with RF amplifier stage, I am using a current source in stage with voltage amplifier. I am testing with 10mv input ac signal and all I pick is noise. in otherwords no output. My motive for using current source is to be able to turn a wide range of frequences atleast three FM stations.

    I am not sure if my component calculations might have issues or the BJT 3904 that am using is the one causing trouble.

    From your first post, your circuit is not clear, and neither is your problem. What do you mean by "might have issues or the BJT 3904"?

    Please post a schematic diagram and your design assumptions.
