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.

(Industy Canada, April 1995, modified 30 July 2009) SP 30-896 MHz, Part II — Spectrum utilization policy for the mobile, broadcasting and amateur services in the frequency range 30 MHz - 896 MHz.
5.1.1 Overview: 30 MHz - 50 MHz states “This upper band portion includes experimental radio systems…”
The deployment of licence-exempt low power applications in this range will be permitted as a secondary service that is, on a non-interference basis without protection from interference from licensed users. The terms for licence-exempt applications for low power and very low power systems are set out in Radio Standards Specification - RSS 210. Therefore, such devices should not interfere with licensed stations and will operate on a non-protection and non-interference basis. Such devices are deemed to be technically suitable for licence-exemption in accordance with radio standards emission requirements.
http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf09084.html
Industry Canada radio regulations, 30 July 2009, RSS-210 - Low-power licence-exempt radio communication devices (all frequency bands), Annex 2 (Devices operating in non-service specific licence-exempt bands in Canada), section 2.7 allows the use of 40.660 MHz - 40.700 MHz for experimental radio systems on a no licence necessary basis if the antenna power output is 16 milliwatts effective isotopic radiated power (16 mW e.i.r.p.) or less.
Experimental radio systems are allowed outside this frequency range but at the reduced power level of 3 nanowatts effective isotopic radiated power (3 nW e.i.r.p, 0.003 µW e.i.r.p). Power allowed for licence-exempt operation on 49.820 MHz – 49.900 MHz is 3 nW e.i.r.p. equal to 0.003 µW e.i.r.p.

Very low power ISM radio beacons in New Zealand.
Ministry of Economic Development MED, New Zealand document Radiocommunications Regulations (General User Radio Licence for Short Range Devices, Notice 2007 (last updated 18 March 2008) states that a general user radio licence is granted for the transmission of radio waves for the purpose of Short Range Devices (SRD), also known as Restricted Radiation Devices (RRD), Low Interference Potential Devices (LIPD), or Spread Spectrum Devices (SSD).
If interference results a user must change frequency reduce power, or cease operation.

FCC 10 July 2008 Part 15 radio regulations, page 93, section 15.231 (e) allows operation with no license for any emission on 40.660 MHz – 40.700 MHz (40660 kHz –- 40700 kHz) if the field strength of the transmission does not exceed 1000 microvolts per metre at a distance 3 metres away from the antenna.

Federal Communications Commission FCC, 10 July 2008 Part 15 radio regulations, page 96, section Section 15.235 (c) for a home-built intentional radiator (transmitter) as defined (below) by 15.23 (a), operating within the band 49.820 MHz – 49.900 MHz (49820 kHz – 49900 kHz) the following standard may be employed:
(1) The RF carrier and modulation products shall be maintained within the band 49.820 MHz – 49.900 MHz.
(2) The total input to the device measured at the battery or the power line terminals (power supply) shall not be more than 100 milliwatts (100 mW) under all conditions.
(3) The antenna will be a single element 1 metre or less permanently mounted on the enclosure containing the devise.
(4). Emissions (signals) outside this band shall be attenuated (keep low, suppressed) to at least 20 dB below the level of the unmodulated carrier.
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.

How to move the antenna from a horizontal to a vertical position in Galkayo, North East Somalia.
The Radio Free Somalia (“Free for all to use” later known as Radio Galkayo) built this 13 element Log periodic short wave radio antenna with a 4 kW balun covering 6.5 – 30 MHz.
The antenna is being tilted from a horizontal to a vertical position in Galkayo, North East Somalia.
The Rotary Club of Boulder, Western Australia and the Australian Government funded the antenna and upgraded the radio stations equipment. It was installed in August 1994 by two Australian volunteers, Abdikarim Nur Mohamed (ham radio callsign 6O0W) from Melbourne and Sam Voron (ham radio callsigns VK2BVS, 6O0A) from Sydney.
North East Somalia became the Puntland State of Somalia on the 1st August 1998.
