BUILT A $200 HIGH POWER AMATEUR TELEVISION TRANSMITTER FROM A MICROWAVE OVEN on 2430 MHz (2.43 GHz). Do not built this unless you are experienced, beware the 5000 Volts it can kill you, do not point the antenna at people, do not look at the antenna, buy a microwave leakage detector. Follow all the precautions.

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.

How to make a radio station in Somalia.
How to make a radio station antenna in Somalia.
The antenna is pulled up from the top of the tower in Galkayo, North East Somalia.
The Radio Free Somalia (“Free for all to use”, later known as Radio Galkayo) antenna is a 12 element Log periodic short wave radio broadcast and worldwide communications antenna. The aerial is being pulled up the tower at the Galkayo Police station, Galkayo, North East Somalia in August 1994.
In 1993 HAM Radio (Helping All Mankind and woMankind) friendship from two-way radio communications brought this aid from Australia to Somalia in August 1994.
As well as short wave radio broadcasting this antenna was also used in amateur radio communications between Somalia hams (Helping All Mankind and woMankind) radio operators and hams worldwide.
Some of the activities of Somalia ham radio and the worldwide network of Ham radio operators include:
To have trained radio operators available throughout the country that can assist their community and the nation during time of emergency. In lasameeyo koox raadiye obaraytaro ah oo diyaar kunoqota dalka gudihiisa kuwaasoo gacan siinkaraya dadkooda iyo dalkooda xiliga ay masiibooyin deg deg ah.
To be ready to help your community, the nation and the world with emergency communications in a disaster. In diyaar loo ahaado iskuxirka tuulada qaranka iyo aduunka marka gargaar deg deg ah loo baahanyahay.
To open emergency communication capability in areas where none currently exists. In laga furo awood is gaarsiineed oo deg deg ah goobah aysan kajirin.
To increase the knowledge and education of people through technical know how in worldwide radio communication. In kor loo qaado aqoonta iyo wax barashada dadka baranaya isgaarsiinta radiyaha caalamiga ah.
To improve communication between villages and urban or city centres. In kor looqaado isgaarsinta udhaxaysa tulooyinka, magaalooyika iyo caasimadaha ha.
To set up local, national & international amateur radio communications. Inlataago raadiyaha shati haystaha ah ee caalamiga ah iyo mid dalka gudihiisa ah si ay xiriir usameeyaan.
Provide a way in which citizens can make friends all over the world for Somalia on the airwaves. In lasameeyo nidaam ay muwaadiniintu xiriir saaxiibtinimo kula yeelanayan aduunka dalka Soomaaaliya ayadoo la adeegsanayo hirarka hawada.
Build friendship worldwide through "on air" radio conversations. In ladhiso saaxiibtinimo aduunkoo dhan ah oo loomarayo wada sheekaysiga hawada.
North East Somalia became the Puntland State of Somalia on the 1st August 1998.
