RADIO RESCUE- after learning Morse code and setting up his own Amateur Radio station, a twelve-year-old boy sends a message that leads to the rescue of a family stranded by a hurricane in Florida, USA.

HOSTAGE IN THE WOODS- In a remote Oregon cabin, kidnapped Ham Radio operator, Kim Stafford, KA7SJP, is taking care of a wounded bank robber. She knows that if he dies, she will too. And he is growing weaker every hour. Kim’s only hope is the small 144 MHz transceiver in her pocket. But no one can hear her signal.

EASY TARGET- Kim, KA7SJP, and Marc, KA7ITR, find themselves at the heart of a dangerous mystery involving dead whales, cocaine traffic, and a South American lumber freighter. Kim sees too much, and the drug dealers are out to get her.

DISAPPEARING ACT- Kim Stafford is delighted to accept an invitation to baby-sit three children for a week while they all sail along the Pacific Coast. But an ex-con, masquerading as the shipboard magician, has his eyes on the four year old Jason. His goal, kidnapping and a three million dollar ransom. Kim and her friend, Marc, fight to save a little boy’s life.

A SPARK TO THE PAST- Kim and Marc find themselves back in the past on a wagon train in 1845. Their knowledge and ham radios are their only chance for survival.

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 operation of this devise can be for any purpose where the transmitter is part of a fixed indoor infrastructure involving connection to AC power. An external antenna is not allowed. The signal must not be intentionally directed outside through a window or doorway. Attached to the devise should be a sign “this equipment can only be operated indoors. Operation outdoors is a violation of 47 U.S.C. 301 and could subject the operator to serious legal penalties.

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.

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.

92 GHz – 95 GHz for any indoor use including radar is limited to a maximum 20.4 Watts e.i.r.p. This is a power density of 60 µW per centimeter squared (60 µW per centimetre squared).

Mopra Observatory, Warrumbungle Mountains near Coonabarabran, N.S.W., Australia.

Mopra Observatory is a single 22 metre radio telescope designed for the EHF 3 millimetre band (3 mm) 76 GHz to 117 GHz.

Mopra Observatory is used as part of the Australia Long Baseline Array of radio telescopes.

Mopra Observatory is also used on its own to monitor radio signals in the millimeter band (EHF).

Mopra radio telescope covers 3 radio bands between 16 GHz to 117 GHz in the SHF and EHF bands:

12 mm band from 16 GHz – 27 GHz (SHF band),

  7 mm band from 30 GHz to 50 GHz (EHF band) and the

  3 mm band from 76 GHz – 117 GHz (EHF band).

Paul Wild Observatory, Narrabri, N.S.W., Australia.

The Australia Telescope Compact Array has six 22 metre antennas which receive signals from Outer Space.

The Paul Wild radio telescopes receive radio waves from outer space in UHF, SHF and EHF bands.

The Paul Wild radio telescopes often use these frequencies to receive radio waves from outer space:

 20 cm band on 1750 MHz (1500 MHz – 2000 MHz UHF band),

 13 cm band on 2450 MHz (2200 MHz – 2700 MHz UHF band with small narrow band interference on 2493 MHz from Globalstar satellite mobile phones),

   6 cm band 5500 MHz (4476 MHz – 6524 MHz SHF band),

   3 cm band 9000 MHz (7976 MHz – 10024 MHz SHF band),

12 mm band 17000 MHz (15976 MHz – 18024 MHz SHF band),

12 mm band 19000 MHz (17976 MHz – 20024 MHz SHF band),

  7 mm band 33000 MHz (31976 MHz – 34024 MHz EHF band),

  7 mm band 35000 MHz (33976 MHz – 36024 MHz EHF band),

  7 mm band 43000 MHz (41976 MHz – 34024 MHz EHF band),

How to build a radio station in Somalia.

How to build a radio station antenna in Somalia.

The antenna is being positioned to attach to the vertical pipe on the top of the tower in Galkayo, North East Somalia.


In August 1994 a Somalia family walk along the Galkayo to Bosasso Highway passing the front of the Galkayo Police station during the mounting of the short wave radio antenna at Radio Free Somalia (“Free for all to use” known later as Radio Galkayo).

Notice that the front wall of the Police station was just rebuilt and has no sign. A later photo shows this same wall shortly after with a painted sign.

North East Somalia became the Puntland State of Somalia on the 1st August 1998.
