Email on HF Radio

Posted: June 19, 2007 in Information, Technology

My friend Stanley got me going on this little project he did while in school. It was about using a HF radio and connecting to the internet. Anyway….Stanley aroused my interest so I did some searches on google and realise the potential HF Radio can be for Papua New Guinea.

Currently in Africa, Bushmail is a worldwide Email that works via HF Radio. It is extremely robusts and can even work during a cyclone. If this was successful in Africa, imagine what advantage it can do for Papua New Guinea. With the difficulties in communication and transportation, this Email over HF Radio may be the saviour for many of our citizens.

It only requires;

  • Antenna (can be suspended on a tree)
  • HF Radio
  • HF Modem
  • Computer (Laptop will do also)
  • 12 Volts DC battery (Solar panel for rural areas)

If you have a landcruiser, you can have an antenna on it and have your laptop pc powered by the cigarette lighter plug and wollla !!!!, you can check you email and even send email on your HF Radio. You cannot browse the internet for that matter as the internet requires you to transmit and receive at the same time.

Two-way radio is a classic half-duplex medium of communication, that is you either trasmitting — push to talk– or receiving, not both at the same time. So we can store emails and send and also receive emails and check them off-line.

I am going to try this at my backyard and see if it works. I wonder if I can use skpye on this also. Because I am either talking or listening. If it does work……imagine the possibilities of endless phone calls for FREE!!!!

But more importantly is the benefits it will bring to rural clinics, aid posts and hospitals.

    Great idea Rex, Data Nets were and I still think are offering HF Radio modem connections.

    In regards to the landcruiser idea I remember seeing a documentary once about a community in Thailand I think it was. Which had guys on motorbikes fitted with WIFI gear and the drove past villages picking up email via their motorbikes. They then took the emails into town to a satellite link up and sent the emails from there.

    As you say it will ideally be for emails only. Well bro set it up and let us know if it works! I think after you have a working demo then you can try sell it’s usefulness to the health department, etc.

    My tambu has already a HF Radio…he uses that to talk to his friend in Aust. His HF Radio is on secured on his two-wheel drive and I think he may have another one at home.

    All I need now is a HF modem so I can connect my laptop to it. Let me check Data Nets for the HF Modem and try the connections.

    This is great, Rex.

    I have bee researching a bit and writing about telemedicine and how we can use recent developments in ICT to improve the quality of health services to rural PNG. This approach is the best I have heard so far. I have been thinking about how Drs in rural areas and other health workers like HEOs can use such cost-effective ICT to consult or for continueing medical education purposes with a specialist or a senior dr in a base hospital or even overseas.

    One main reason why drs do not like going to the bush to practise is because once sent there, they are largely forgotten and have no connection with developments in medicine.

    I will follow this up and try out some pilot projects in the future. Have to find some sources of funding first though.

    Maybe I can catch up with you and Manu when I’m in POM and discuss to see if we can put a proposal together to seek some donor funding and try out a pilot project.

    Em tru yah……Doctors don’t always want to go out to rural areas for fear they may get lost in time 🙂

    It’s something we can contemplate and see if workable. Lets give it a try and see if it is possible.

    Will let you know when I am in POM.

    BTW, what kind of software does this email system use?

  7. Joe says:

    Hi all, this is a great discussion and am in for the telemedicine. This will be useful in PNG and if this project rolls out. This will be great.

    Interms of the software, our company is into negotiation of a open source software ISI Box which is simply a network in a box. We will be piloting this new product in PNG and this will come in hand with all this if you are too set up a network .

    Interesting topic on using HF E-mails in PNG. There is one such Company in PNG which has been using HF-Email for missions, Churches and rural outpost for well over 7years as far as I can remember. I use HF-uuPLUS software so check that online, folks. Codan Radios, check their website. They have that technology up and running. Mail is limited to txt and few graphics. I think Wils discovery into overcoming that by huge mb via HF broadband is interesting to note.
    Check Christian radio in Goroka, you might get an answer for HF-emails

    does anyone knows if there is any other information about this subject in other languages?

    This is a comment concerning the one by Joan on the 11th of March 2008, and Slade on the 24th of March 2008.

    Revolutionary is not a sequencial change or a upgrade of things. It is not a rearrangement of formula.

    Revolutionary is a complete change. It is not only rearranging the plates around, however it is both rearranging the plates and turning them upside down.

    Amai is making a revolutionary change in PNG’s Communication Technology.

    I am one of his students, and I’ve seen so much in him.

    Keep up the Good Work, Sir.
