I have a yeasu rig and a mfj versa tunner when i transmit cw and turn my power up my tv goes crazy and downstairs the china cabinet lights blink. my antenna is a end fed dipole connected to the wire terminal to my versa tuner i have a ground rod connected to my versa tunner and my yeasu i take it this is a grounding problem my shack is on the top floor i have a 2 story brick house and the cable goes out the window down to the ground rod so i presume since the tuner is grounded this should take care of the end fed cable. so far i can not feel any hot spots while i tne my rig or tuner.
