[RFI] Nineteen Hour Noise

[tlthompson]

Ron,

I am not sure, but I think the reason the noise is worse on 40 m is that 
the line from the ballast to the lamp is about 30 feet (almost 1/4 wave 
length on 40 m).  At least that is the way it has been on every grow 
system that I have seen.  Good luck and do keep us informed.

73,   Tom   W0IVJ
