Hi Don,
Here is an update for the group concerning grow light ballasts. I have
posted links to two commercial filters and an EMI test of a Galaxy
ballast. The link to my web site is:

The new information is at the bottom of the page.

If ARRL, NAB and the greater amateur radio and broadcasting communities would
distribute this and similar articles as far and as wide as possible, people
carrying out illegal operations would become concerned (or paranoid) enough
about the possible RFI they are generating, to make damn sure their grow lights
are clean. Vendors selling the lighting systems will quickly get the message
and clean up their products, and the problem will abate of its own accord,
sooner, not later. If you suspect one of your neighbours is causing this
problem and want to get rid of the interference without getting involved with
cops, thugs, gangs, reprisals and court subpoenas, just print off copies of the
article and anonymously mail it to the suspected culprits, or slip it in their
letter box or leave it on their doorstep, and the noise just might inexplicably
disappear.
Someone should forward this and similar articles to "High Times" magazine and
other like-minded publications and webs sites; it would be nice to get the DIY home grow
operations paranoid enough to buy better lighting fixtures. I couldn't care less if
someone wants to grow their own weed; just make sure your usage or creation of mind
altering substances doesn't negatively impact anyone but your own self.
This is a rare case where amateur radio operators, AM broadcasters, and other
users of the MF and HF spectrum have RFI culprits by the part of the anatomy
where it hurts, if we would just take advantage of the opportunity.
