[Elecraft] Ceiling fan interference

[Brian Hunt]

Sounds like a pulse width modulation  controlled variable speed DC motor. Their website doesn't give any details other than the DC motor. There is a tech support link on their website you could query them. 

Similar to the problems hams have with the new high efficiency furnaces?  I have one of those that I tamed with some ferrite clamp-ons on the thermostat line.
