[aprssig] Tesla Field Day mode (or any EV/Hybrid) at work

[david vanhorn]

Imho they need to drop the a and b lines by 10 to 20 db.  I usually pass by
more than 30 without any shields or other costly measures and the products
I design are receiving signals that almost aren't there.  Emi from gopros,
phones, and other nuisance emitters can cause enough interference to block
the signal I'm listening for and then someone dies.
