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.
