As an aside--
We in the "legal grow" states thank you, and the ARRL for testing and
reporting those offending lights! Here is an example as to why your
tests will help...
It is a real mess in my local area right now-- as soon as one grow
operation gets quiet, another starts making RFI... There is one RFI
source that has been going on now for three years, and is 60 over S9 at
one fellows Amateur Operator's home, on all HF bands, every night, 80-10
Meters... It is only 10 over S9 at my location 1/2 mile from him.
I know the source is within several hundred yards of his antenna, but we
have been totally unable to pin it to a single home due to geography,
home placement, and underground power lines. One literately needs to
climb a 45 degree hill with test gear just to test from his backyard.
This RFI source is affecting at least five hams now...
We are doing another triangulation run this summer from very close in to
the source, and on as high a frequency as we possible... I am building
several loops now... That should help, then we contact the FCC...
Without a house to point at, we are simply at the mercy of this sort of
thing... We have finally started giving handouts to the local pot sales
outlets covering what RFI is, and why it is bad...
Until the FCC bans the import of all RFI generating lights, and enforce
that ban, our only real hope is what you and the ARRL are doing to get
the items banned as far upstream as possible... So we really do
appreciate your efforts in this matter Ed! Thank you and your staff
Thanks and 73's,
