Schematic of the 4 tube radio, experimentally built in a way of the radio-pioneers (1910-1945). The radio acts as a cascade type receiver when the antenna coil has a high self-inductance, with lower self-inductances of the antenna coil you can put in a mixing process with the oscillator. Perhaps...

The X-Band microwave motion detector was moved to 10.25GHz. We explore the output of the HP x421A detector diode attached to the HP x532A X-Band wavemeter, and verify the frequency of operation.
