Hi,
i am a recent K3 owner and i live at 15 km from a 300 kW AM station on 864 kHz,
on 80m dipole S-meter rise up to S9+55 with 10 dB attenuator ON.
On dummy load i can read S1 in AM or SSB, without BPF option.
With jumper between pins 1 and 3 P44E RF board, no change.
80 WAS poor and 160 unusable until i put a common mode choc in DC cable.
i got my best result with 8 turns on 4x FT-240-43 stacked.
Is anyone with experience in chocs on DC line ?
