All the listed radio hams are competent and friendly people.
There is neither fixed charge nor certain delivery time.
All the details are agreed with the builder.
Any amateur radio operator around the world who would like to be added to this list is welcome to make contact in 2009.
Sam Voron VK2BVS sent this email to Juma kits on 16 October 2009.
Thank you for the work you have done to make the 500 kHz transmitter receiver kit,
I would like to suggest some future kits that might be good introductions to amateur radio.
1. A transceiver below 9 kHz would be an interesting kit especially as no license is required in many countries.
2. Where no antenna is available an interesting feature might be to feed the 9 kHz transmitter kit into power lines as is done with home power line intercoms.
3. A walkie talkie kit below 9 kHz would be another amazing project.
Please keep up the great product development.
Regards,
Sam VK2BVS, 6O0A in Sydney, Australia.

Hello Sam,
Nice to hear that you are interested in JUMA transmitters and tnx for the encouraging comment.
Your idea is neat. We will consider your 9 kHz suggestion.

1 kHz of the 500 kHz band has been left clear for use by marine radio enthusiasts who purchased unwanted coastal radio stations and turned them into museums that occasionally demonstrate the art of Morse code using 500 kHz transmitters.

On 28 July 2009 the FCC granted a modified license allowing 45 amateur radio stations across the continental USA, Alaska, and Hawaii to operate from 0.495 MHz – 0.499 MHz and 0.501 MHz – 0.510 MHz using 20 Watts effective radiated power (20 Watts ERP) using Morse code (CW), QRSS (Slow Morse code) and the digital radio transmissions Phase Shift Keying (PSK31), Frequency Shift Keying (FSK31) and Minimum shift keying (MSK31).

For Amateur radio operators who love experimenting with AM there is the possibility of building AM STEREO transmitters and receivers to bring the technology that failed to take off in the 1980’s to life in the 21st century. I recall hearing and enjoying the improved audio quality of AM STEREO in Sydney, Australia during the demonstration of an AM STEREO receiver while listening to Radio 2UE with and without stereo.

526.5 kHz – 1605 kHz 300 metre band (300 meter band).
In the MF bands where no transmitter licence (license) is needed the maximum antenna radiated power is shown for each band:

300 m band 526.5 kHz – 1605 kHz using a very low power instructional “Build your own AM radio station” electronic kit radiating within your private residence.
These very low power 526.5 kHz – 1605 kHz electronic kits are legal if the radio signal is within your home residence and does not cause radio or TV interference. This is not in the Australian Low Interference Potential Devices LIPD document (See Australia in- Radio Broadcasting Section, MW AM legal unlicensed radio).
The Australian Communications and Media Authority ACMA (Low Interference Potential Devices LIPD class license 2000) with all amendments came into effect on 1 July 2009.
LIPD allow transmitters 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.
LIPD, Section 3A, page 4, Definitions says: “This maximum EIRP means the largest amount of equivalent isotropically radiated power that is radiated in any direction from either an antenna that is an integral part of the transmitter or an antenna that is connected to the transmitter.”
The maximum antenna radiated power for all transmitters that do no require a license request starts on page 7, schedule 1 Transmitters, all transmitters.
The LIPD (no license required) page 7 covered the 800 metre band (325 kHz – 415 kHz) in an earlier document.

Medium Frequency Radio Beacons have been established by individual hobby radio enthusiasts in their home to see how far such radio waves can travel.
LF hobby radio listeners can use computer aided software to extend the range at which it is possible for a radio receiver to detect these low power radio beacons.
Industry Canada 30 July 2009 radio regulations RSS-210 (Low-power licence-exempt devices operating in licence-exempt bands), Annex 2: Devices Operating in Non-Service Specific Licence-exempt Bands, section A2.2 states that in the 510 kHz – 1705 kHz band no license is needed for systems that limit the total input power to the final radio frequency stage of the transmitter to 100 milliwatts (100 mW), and the total length of transmission line and antenna ground lead (if used) to 3 metres in 2009.

(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.

The second Somalia Amateur Radio training course was held in Galkayo, North East Somalia in October 1994.
Amateur radio 1994 qualifying course for the operation of unrestricted amateur radio stations in Somalia.
1994 Koorsada lagu qalinjabinayo farsamada howlgalinta raadiyeyaasha shati doonka ah ee aan xadidnayn ee yaala gudaha Soomaaliya.
After the first Somalia amateur radio training course in Galkayo, North East Somalia was completed in August 1993, Sam Voron VK2BVS, 6O0A from Sydney, Australia conducted a second Somalia Amateur Radio training course in October 1994.
New staff from Radio Free Somalia (“free for all to use”, known later as Radio Galkayo) and those that had not completed the amateur radio training in 1993 had a second opportunity to qualify for the Somalia amateur radio license which included a personal lifetime internationally recognized HAM (Helping All Mankind and woMankind) radio callsign.
The photo shows the radio students in August 1994 at Radio Free Somalia (“free for everyone to use” known later as Radio Galkayo).
Two Australian volunteers Sam Voron VK2BVS, 6O0A from Sydney and Abdikarim Nur Mohamud 6O0W from Melbourne called for any Somali’s who wanted to learn about radio for the purpose of service to Somalia without money or food.
These Somalia volunteers were trained and added to the 1993 staff of the radio station.
To learn the meaning of “service to Somalia” the HAM (“Helping All Mankind and womankind”) radio course introduced the concept of service to the community through the building of knowledge in radio and and using that knowledge to serve others not for money but for the pleasure and honour of using knowledge to Help All Mankind and womankind.
North East Somalia became the Puntland State of Somalia on the 1st August 1998.
