US2 In the band 9-490 kHz, electric utilities operate Power Line Carrier (PLC) systems on power transmission lines for communications important to the reliability and security of electric service to the public. These PLC systems operate under the provisions of 47 CFR part 15, or Chapter 8 of the NTIA Manual, on an unprotected and non-interference basis with respect to authorized radio users. Notification of intent to place new or revised radio frequency assignments or PLC frequency uses in the band 9-490 kHz is to be made in accordance with the Rules and Regulations of the FCC and NTIA, and users are urged to minimize potential interference to the extent practicable. This footnote does not provide any allocation status to PLC radio frequency uses.

LowFER Band
Current Use
160–190 kHz LowFER band
The Low Frequency ExpeRimentation (LowFER) band encompasses a range of frequencies for low power experimental use allowed by the FCC's Part 15 rules. Radio experimenters operate beacon stations in this band. Part 15.217 of the FCC's rules allows up to 1 watt of input power to the final stage of the transmitter, and up to 15 m total length of feed line and antenna. Such limitations create very challenging circumstances for communication over any significant distance, but that is the challenge that attracts many experimenters.
