What is the name of the condition that occurs when the signals of two transmitters in close proximity mix together in one or both of their final amplifiers, and unwanted signals at the sum and difference frequencies of the original transmissions are generated?

🔍 Key Concepts

• Transmitter spacing and nonlinear mixing in power amplifiers • Difference between receiver desensitization/overload and mixing products between two strong transmitters • Definition of intermodulation products (sum and difference frequencies)

💭 Think About

• Which option specifically refers to new, unwanted signals being created at sum and difference frequencies of the original signals? • Which options relate more to receiver performance or tuning/adjustment, rather than the creation of new signals between two transmitters? • Think about what happens when two strong RF signals hit a nonlinear device together—what is that effect usually called in radio theory?

✅ Before You Answer

• Identify which choice is defined in radio theory as generating sum and difference frequencies of existing signals • Eliminate any options that primarily describe weakening or detuning an amplifier rather than creating new frequencies • Confirm that the remaining term is commonly associated with multiple strong transmitters in close proximity causing extra signals on other frequencies
