The Australian Radio communications (Low Interference Potential Devices LIPD class license 2000) with all amendments came into effect on 1 July 2009.
This document (LIPD 2000) includes the amendments to 2009 to allow devises that meet certain power levels on certain frequencies to be used without the need to apply for a license.
LIPD, (section 3, Note) states that LIPD devises must not cause radio frequency interference to other Radio communication devises.
The responsibility is on LIPD owners to resolve interference for example by retuning or stopping their operation.

The FCC Federal Communications Commission 10 July 2008 radio regulations, Part 15 rules for Radio Frequency devices outlines the USA radio regulations under which an intended radiator of radio waves may be operated without a license.
Unlicensed transmitters (intended radiators) must not cause interference to other radio or TV stations. Unlicensed radio stations (intended radiators) are not protected from interference.
Part 15 rules, page 13, section 15.23 allow home built transmitters (Intentional radiators).

The FCC Part 15 radio regulations for home-made radio transmitter devices.
FCC 10 July 2008 Part 15 radio regulations, page 13, section 15.23 “Home-built devices” states:
(a) Equipment authorization is not required for devices that are not marketed, are not constructed from a kit and are built in quantities of 5 or less for personal use.
(b) It is recognized that the individual builder of Home-built equipment may not possess the means to perform the measurements for determining compliance with the regulations. In this case the builder is expected to employ good engineering practices to meet specified technical standards to the greatest extent practicable.
Section 15.5 also applies to home made devices (transmitters).
Page 9, Section 15.5 “General conditions of operation”.
(a). No person has a right to the continued use of current frequencies (this means that any frequency might be re-allocated for a different use in future).
(b). No harmful radio or TV interference is to be caused and interference from licensed or unlicensed stations must be accepted.
(c). Operation of the devise (transmitter) must cease if an FCC representative informs you of harmful interference caused by your devise. Operation can only restart once the cause of the interference has been corrected.
(d). Transmitters causing damped wave are prohibited (not allowed).
Part 15 rules, page 80 is the list of frequencies where intended radio emissions (transmissions) is not permitted. Only spurious emission (such as unavoidable low level harmonic radiation as a result of transmitting on another frequency) is allowed in those restricted bands.
