DIGITAL INTERFACE

Salam,

Workshop/Bengkel membuat dan setup

Digital interface adalah utk kegunaan penyambung drp handy/rig ke PC, dan ia perlu ada program(software) sokongan , contoh jika disambung ke internet(seluruh dunia) ialah spt Eqso dan Echolink. Dan ada juga tidak perlu melalui internet, seolah-olah kita membina network sendiri menggunakan RF drp handy/rig, contohnya SSTV(menghantar/menerima gambar) RTTY (menghantar mesage

eQSO is a client / server software program designed by Amateur Radio enthusiasts for linking Amateur Radio RF gateways and repeaters via the Internet. the software may be used by licensed Amateur Radio operators and Short Wave Listeners provided the rules are followed.

What is a “Gateway” and what do they do?

· A Gateway (a computer connected to a radio transceiver) facilitates worldwide communications for radio transceivers that normally only have a range of a few miles. A Gateway has two functions:

· Firstly, a radio receives local (short range) amateur radio transmissions. The audio is fed into the soundcard of a computer. The computer, using eQSO Gateway software, then sends the voice data over the Internet (using VoIP- Voice over Internet Protocol) to anywhere in the world where it can be received on another computer using theeQSO software. The receiving computer may be a personal computer fitted with headphones or speakers, or it may be another Gateway.

· Gateway computers receive voice data from around the world, and then feed that data into a radio transmitter, which will send it to local radio amateurs.

· The main advantage of Gateways is that they allow reliable worldwide mobile (or even "mobile to mobile") radio communications (of excellent quality) with inexpensive and low power equipment - even handy talkies!

· Some gateways are called 'simplex links' (those with a “-L” suffix) because the Gateway radio transceiver receives and transmits (alternately) on the same frequency.

· An interface (which switches the transceiver between transmit and receive at the appropriate time) typically uses a signal from the RTS (ready to send) line on the serial port of the Gateway computer.

· A few Gateways are 'duplex repeaters', (those with a “-R” suffix) which use a separate receiver and transmitter on different frequencies.
