It's interesting to learn what you are experiencing in Fargo ND, What's
very interesting is that there's significantly more usage in the 162-174
range than in the amateur radio bands. What might explain this is....
Taking a quick look at the Canada licensing/authorized frequencies structure
at http://spectrum.ic.gc.ca/tafl/tafindxe.html it appears that some of
these frequencies actually authorized in Canada for commercial industrial
usage so equipment would normally operate on these frequencies .
Also wouldn't locations within 150 miles or so of the Canada-US Border have
some sort of an agreement not to use certain frequencies without
coordination? So for example for the Canada truckers illegal usage in your
area, are there any US federal users on these specific frequencies?
IMHO since it is mobile usage, not fixed, and IF it isn't interfering with
any US federal/military LMR system, I don't think the military/federal
agencies are going to spend time trying to track down moving targets!
Also IMHO an outstanding reference source which I highly recommend is
Grove's "Federal Frequency Directory" 2nd edition (now a bundled package
http://www.grove-ent.com/FREQMASFILE.html which provides significant
insight into potential US federal/military users of these frequencies as
shown below.
