Um, isn't this thing doing exactly what it is supposed to be doing? Kind of like those underground cable locators, that send an RF signal into the cable, so you can locate it with a radio. For the c

For the heck of it I googled "120kHz line noise" and the first few hits are about the X-10 (remember that?) remote appliance powerline control system, which appears to use a 120kHz carrier. Don't kn
