Hi All, I had mentioned previously that I just ordered a nice treadmill after a lot of research. When I read about this possible interference I sent an email to the company. Within an hour I got a phone call from a very knowledgeable person. He stated that as far as he knows all treadmills except Precor and Woodway use PWM to regulate the DC motor. He said RFI could emanate from the motor along the AC plug, or radiate from the PWM circuit. He said that if it was from the PWM it would be very difficult to resolve, as it would be picked up by the antenna. He said both types of interference were definitely possible. He also stated that if I wanted to buy a Precor or Woodway I would be talking about $4500 for an entry level machine.
I talked it over with my wife and since I doubt I will be on my K3 while on the treadmill we decided to keep the treadmill we ordered. I feel sorry for any ham who is suffering RFI from a neighbor's treadmill. Better to work with them than to call the FCC on them.
