What are Radio-location Services in the 1.9-2.0 MHz range?
$begingroup$
I'm currently studying for the General Exam and in looking at charts of the new frequency privileges have run across a restriction I would like to have further defined. In the 160 meter band the books all say "1.90 MHz thru 2.0 MHz should be treated as a secondary allocation as we are required to avoid interfering with Radio-location Services in that range."

I wish you well with the general test!
The radiolocation services in question are defined in CFR 47 §2.106:
NG92 The band 1900-2000 kHz is also allocated on a primary basis to the maritime mobile service in Regions 2 and 3 and to the radiolocation service in Region 2, and on a secondary basis to the radiolocation service in Region 3. The use of these allocations is restricted to radio buoy operations on the open sea and the Great Lakes. Stations in the amateur, maritime mobile, and radiolocation services in Region 2 shall be protected from harmful interference only to the extent that the offending station does not operate in compliance with the technical rules applicable to the service in which it operates.

Fishnet buoy beacons are a nuisance just above 1.8 MHz, FWIW.

How would one ever know they are interfering with a buoy's transmissions? Do we just avoid transmitting altogether on 1.9 - 2.0 MHz?

@DaveG The idea is you listen to your transmit frequency. If you hear a buoy, you change frequencies, If not, feel free to keep using the frequency until such time that you do hear one.
