I am building an FM receiver. My problem is that when powering my antenna circuit or LO circuit one at a time, I get the output of those circuits appearing very strongly on my power supply lines.
When I connect both LO and antenna circuits to power, I get an extremely distorted waveform at the output of either. An FFT shows my amplified antenna frequencies, my LO frequency and a ton of large unintended peaks.
How can I electrically isolate these two circuits from my power supply and each other? Pictures of my setup are included.
