Copies of the World Radio TV Handbook (including the 1991 edition) have identified 1485 kHz as a local frequency, akin to the Class C (former Class IV) radio stations in North America which are limited to 1kW.
The following radio stations broadcast on AM frequency 1485 kHz:
2 Shortwave uses a combination of AM, VSB, USB and LSB, with some NBFM and CW/morse code (in the case of time signal stations) as well as numerous frequencies, depending on the time of day/night, season, and solar activity level. A reasonably full list from 16 kHz to 27MHz can be found at [1]
3 Regions 1 and 3 also use Region 2's frequencies as well, with 50 to 100 kHz spacing.
