I had a table radio from the late 1930s that had the 1610-1720 kHz Police Band, and I could hear many of those phone frequencies. However, the signals were Narrow Band FM, and I could hear it by detuning it and using slope detection. The transmissions used Carrier Current transmission, so you could conceivably be an a hot spot in the outdoor wiring perhaps as far as a few wavelengths away. I could never figure out where the signals were coming from, as the standing waves did not behave in the usual inverse field strength relationship, much like Carrier Current radio stations did.
