I am trying to amplify the FM band (88-110 MHz) from a dipole antenna but my amplifier has no output signal.
My antenna is two lengths of wire that are half-wave resonant at ~94 MHz. One wire (not connected in picture) is connected directly to emitter and the other (purple) is connected directly to ground. No transmission line, everything is point to point.
When antenna wires are isolated and probed: one wire touches probe, other wire is connected to probe ground clip. There is a 50 mV peak to peak signal at 94 MHz and some AM noise; antenna works.
When the antenna is connected to rest of circuit, GND clip to circuit ground, I see the same 50 mV signal at the emitter pin of the BJT and base pin of the BJT. Collector/C3 has no VHF signal, but FFT shows massive peaks at AM frequencies. Physical construction uses same schematic and labelled part values as simulation. What could be responsible for this behavior? I suspect I may have created a low pass filter via an input/base/output capacitor and BJT parasitics or a resistor that is causing this collector behavior.
On the backside of the perfboard, there are two lengths of copper tape that serve as (+) and (-) rails. These are connected to the power and ground rails of a 5V USB power supply. The large electrolytic capacitor smooths out the noise from the power supply.
What can I change/fix with this circuit to make it work as simulated?
