I don't know why the FCC didn't follow up, but the lack of follow-up was on our 
end.  A lot was going on at the time. Now that we can test again, I want to 
pick up on this, so poor W1VLF is going to have some work to do. 😊

Can you expand on why the FCC failed to follow up on Home Depot?  Also, 
congratulations on Walmart, I had not heard of that one...  THANK YOU!
