Yes, a radio receiver can be located with another receiver or tracer, most radio receivers is of the regenerative type and it has a local oscillator that is used to generate an intermediate (IF) signal of 465Khz on shortwave and 10.7Mhz on the higher frequencies like a FM or TV receiver, that oscillator is like a low power transmitter that is transmitting an un-modulated RF signal.
Any nearby receiver can pick up this signal although no sound will be heard on the receiver, to be able to hear a signal the tracer is equipped with a BFO, (Beat Frequency Oscillator) that will generate an audible tone when a signal is received, the same way as the local oscillator generate the IF signal but only in the audible frequencies and a signal strength meter, then with a directional antenna, the receiver that is to be traced can be pin pointed.

Which part of a radio receiver separates the audio signal from the carrier?
That's the "detector" or "demodulator" stage.
What are the types of FM receiver?
TYPES OF RADIO RECEIVER • Basic crystal set. • A T.R.F. Receiver. • A Superhetrodyne Receiver. • the Reflex Receiver.
What is A microwave leak detector?
A portable handheld radio receiver operating in the microwave band, that when it detects microwave RF above a certain strength it gives some form of warning signal. This warning may be audible, visual, or be shown on the face of a meter.
Do all motion sensors have a transmitter and a receiver?
Some devices have the receiver and transmitter built into the same device. Some devices use only a detector and register changes in emitted IR "patterns" (for example) to infer motion.
Can you convert an am radio into FM?
Yes, you can. You need to make an FM receiver and attach it to the receiver coil. You'll need to install a switch so you can switch between them, as well.
How does a cobra detector work?
A cobra detector is a radar detector. Radar detectors work the same way a radio receiver does. The radar detector looks for frequencies that a radar gun uses.
Which part of a radio receiver separates the audio signal from the carrier?
That's the "detector" or "demodulator" stage.
What is the purpose of a discriminator in an FM broadcast receiver?
The discriminator, and the ratio detector, perform the same function in an f.m. receiver as the detector does in an a.m. receiver, i.e. it recovers the modulation.
Does a crystal receiver allow electricity through when the transmitter sends a signal to it?
A crystal receiver does not run on electricity. It is simply powered by the radio waves it is receiving. A large antenna is used to receive the signal and moves the signal to the crystal detector or diode.
Where is the fuse on a Yamaha r9 receiver?
The fuses on a Yamaha R9 receiver is easy to find. The fuses are located inside the radio on the left hand side connected to the wall. You will have to take the radio apart to get to the fuses.
What is broadcast receiver?
A broadcast receiver is a radio that receives broadcasts from commercial radio stations.
What is non coherent detector?
A non coherent detector is a type of device that does not need a receiver carrier to be phase locked to a transmitter carrier. A coherent detector demodulates signals.
Can you use a mp3 player radio for making a homemade metal detector?
No, this is not possible. Firstly, MP3 radio's do not exist and an MP3 player is a Music Player, not a metal detector.
What are the types of FM receiver?
TYPES OF RADIO RECEIVER • Basic crystal set. • A T.R.F. Receiver. • A Superhetrodyne Receiver. • the Reflex Receiver.
Can you make a metal detector out of a calculator and a radio?
You can build a metal detector using an AM radio and Calculator.But it is not sure that it will work or not.My brother had made metal detector using an AM radio and calculator two months ago,first it doesn't work at all but than he made some changes than it began working.Gurjot Singh Sodhi
What type of radio receiver do not respond to static interference?
FM radio is inherently less sensitive to natural noise ... not immunebut significantly less sensitive ... than AM radio is.
How do you put a new remote control on a nitro RC car?
it is quite easy if it is a simple radio system, all you have to do is make sure the frequency chips are the same, located in the remote and in the radio receiver thing.
