Sensitive RF Field Meter Circuit - Pinpoint Transmitters

Very simple but handy circuit to have when testing/adjusting FM transmitters. The circuit shown uses a minimum amount of components, and when using the correct meter(100uA), it is extremely sensitive and can be used for pinpointing hidden FM transmitter locations using the zeroing knob. Schematic can be seen in the video. This circuit detects the energy emitted from my cell phone better than my expensive tri-field meter!
