I have a WalGreens in town that has 8 microwave door openers. Now, since the day it opened, I have never got an alert that store...even from 25 feet away in the parking lot.
Glad I do not pick up 8 microwave sources with my V-1. Wish ALL stores had those type of door openers! ( I should actually look closer to see any information on them for freq, etc...)
I think V-1 does a great job of selectivity OR the door openers are so out of the normal freq range.
