[TenTec] High speed washer hum/whine

[Jeff, W4DD]

Step 1 - disconnect antenna to rule that out.

Step 2 - try simple stuff, like wrapping the power cord around a ferrite
core

Subject: [TenTec] High speed washer hum/whine

Good afternoon all,

Here is a powersupply problem that needs a neat fix.

When my wife runs the highspeed washing machine, the whine and hum goes up 
and down and also off and on when I am on my trusty Delta II.  The power 
supply is the # 936.  Grounding all around.

When I run my old Drake, with AC-4 power supply - theer isn't a hum or 
whine. (My gues would be the L-C filters on both neg and pos AC Lines.

Suggestions Please.
