[Elecraft] OT: Maytag Bravos RFI

[N2TK]

Just thinking about this. Is it across all HF bands RF type pickup? Or is it
band specific? Is it only when the drum motor is running or is the RF noise
there all the time the washer is on? 
Is the noise being picked up from the shields of the coax - do you hear the
RF noise if you disconnect the cables from the rig and short  or 50 ohm
terminate the coax connector(s)?

putting front load technology (computer/switcher) in top load 
washers. The clue is if the washer will only accept HD detergent.

Don,

Many thanks!  I'm forwarding this email to the RFI list, where there 
has been considerable discussion on this topic.
