[SixClub] Monitor RFI

[Zeb Palmer - KD7EVS]

She doesn't notice a difference in refresh rate.  So it's left on 60hz and I
don't have RFI.   I do need to get her a flat screen though, cause I need
one. I know I can't have one till she does! 

Though I have around 20 computers in my server room and only one monitor.
she has one computer and one monitor, I'm the one with a low monitor to
computer ratio!   Btw, I can operate 6m qrp in my server room.   Everything
is pretty quite, did have to replace one or two powerstrips to reduce some
noise.   Everything is grounded to a central point as is anti-static mats on
my workbench.

Hi!

Buy her a flat panel monitor! You will make her happy
and you can say goodbye to the interference!
