If you are not receiving any transmissions, what should you check?

Choosing to check whether the frequencies of the transmitter and receiver match is essential when you are not receiving any transmissions. In any wireless communication system, the transmitter and receiver must operate on the same frequency for the communication to be established successfully. If there is a mismatch in frequencies, the receiver will be unable to pick up the signals from the transmitter, resulting in no transmissions being received.

Frequency matching is fundamental to the operation of the system, and without it, the signal can be entirely lost regardless of other factors present in the setup. Therefore, confirming that both the transmitter and receiver are set to the correct corresponding frequencies is a crucial step in troubleshooting reception issues.
