Just hooked up an oscilloscope to my HF antenna feed line and it looks like I'm getting a large ~1 MHz signal from the antenna before being filtered in the transceiver to receive 14.074 MHz.
@neptune22222 local AM broadcast station?
Good point. Yes, I found a right wing AM radio station with very strong signal at 1.08 MHz. Ads about buying gold and besthotgrill.com. AM1080 Santa Cruz.
@neptune22222 KSCO has a fair bit of poke, 10kW day, 5kW directional at night. That'd induce a bit of voltage on your HF dipole!
@weezmgk Ah thanks.
Looks to be just under 80 mV p-p from about 4 miles away on my 23.5 foot vertical, half dipole.
@neptune22222 that's about right. Your antenna is working fine, if that's any consolation. If their xmtr is in good shape, without any significant spurs, it shouldn't bother you
