What kind of equipment do you think these truckers were using to jam
with?

Cheap. *Google....

I've seen intermittent loss of GPS signal at low altitude twice this
Summer... now I know why. *In both cases I was very close to a
highway.

Things that make you go "grrrrrrrrrrr."

I know of no equipment carried by truckers that jam GPS. The FCC and
others would be very interested.

Why would truckers want to jam GPS? *Also, I did a Google search, and I
only see jammers that work within 30 feet.

From "The Economist":

"Such devices are illegal to sell or use, but they have become popular
with commercial drivers who object to their employers tracking their
every move. A jammer prevents a tracking device in the vehicle from
determining (and then reporting) its location and speed—but it also
disrupts GPS signals for others nearby."
