[RFI] Keurig coffee vs Astron Rs35M

[KD7JYK DM09]

: Every time I turn on my Keurig K-Cup coffee maker I've been hearing a
: very loud sound like a low loud hum coming from my Astron RS35M power
: supply.

Mine did that when I ran an electric coffee pot upstairs.  A line monitor 
indicated about a 6 volt drop in the AC circuit and the RS-35 would hum. 
Pot heater turned off, voltage went up, humming stopped.

I have a Vornado fan in the hall that does the same thing.
