[RFI] Low RFI 60w CFL bulb

[Jim Brown]

Hey Chris,

This is excellent work and information!  Thanks for doing it, and for 
posting it.  I hope Ed Hare will pick up on it.  He's in a position to 
go to the big box stores about it!

He may want your samples, or he may buy his own.  If he doesn't want 
them, I strongly suggest that you take them back for a refund, telling 
them why.

Another thing for you to try -- get someone to switch the bulbs on and 
off while you listen in your ham rig.

73, Jim K9YC
