[Elecraft] Noise sources

[Bob K6UJ]

Thanks Kevin
I checked my families cell phone chargers and I'm OK (for now.)
It never ends.  I periodically shut off the main breaker to our house and listen on HF with battery power to see if there are any new RFI culprits.  My kids are 
always using some new electronic gadget.  I just discovered 
that my Seagate Free Agent Pro external hard drive is radiating RFI  like crazy.
I can pick up its radiation from my HF rig in the car parked in front of the house !   I should call Seagate 
and inform them that they need to apply for an FCC license and get a call sign for my hard drive.  hihi.

73,
