[RTTY] Noisy PC Power Supply

[Thomas Giella KN4LF]

Speaking of power supply noise my two PC's made allot of racket. I placed 
split beads on all of the leads but it did little to quiet them. Then as an 
experiment I decided to ground the PC power supplies to my radio station 
ground fully expecting more directly coupled noise.

But to my amazement all of the noise disappeared, even the very noisy Radio 
Shack 25 amp switching power supply was quieted!
