[RFI] Grow Lights

[Dave Cole]

I have changed the name on a spare wireless router I have to 
LE_SURVIAL#3".  We will see if that has any effect.

We went around the neighborhood with some very intimidating-looking antennas, electronics, and laptops.  The interference ceased after about 30-minutes of 'being obvious' on the hunt for the problem location.  We suspect whomever was conducting the operation saw us and got scared.  It's never come on again, even after 5 months.  Take all the geeky equipment you can, even if it doesn't work anymore, lots of antennas, even a few things that go 'click' or squeal.
