Can anyone provide a model of how common-mode signals enter and are
amplified on a radio receiver via the coax shield of the antenna?
This seems to be the entry mode of a VY STRONG BCI in a
contest-station. 50+ dB notch filters on the BC frequency
(differential mode filters) have proved useless.
BC has 10kW out on 1584 KHz and antenna is only 100m away from 160m
Thanks in advance.
