Consider again a Tuned Radio Frequency Receiver required to tune to 36.5 MHz, the upper end of the shortwave band. If the Q required of the RF circuits is again calculated, still on this basis of a 10-kHz bandwidth, we have Q = 36,500/10 = 3650! It is obvious that such a Q is impossible to obtain with ordinary tuned circuits.Method 2: Test the receiver for interference. To test the receiver for interference, try the following methods: If your wireless device has a button to synch to the receiver, press the button to resynch the device by selecting a different channel.
