What is the Internet Radio Linking Project (IRLP)?
The correct answer is A: A technique to connect amateur radio systems, such as repeaters, via the internet using Voice Over Internet Protocol (VoIP). The Internet Radio Linking Project (IRLP) is a technique to connect amateur radio systems via the internet using VoIP. IRLP allows repeaters and other radio systems to be linked together over the internet, enabling worldwide communications. For amateur radio operators, IRLP extends the range of local repeaters by connecting them to repeaters worldwide, allowing contacts that wouldn't be possible with radio alone. Understanding IRLP helps explain how internet-linked repeaters work.
Exam Tip
IRLP = internet linking using VoIP. Think 'I'RLP = 'I'nternet 'R'adio 'L'inking 'P'roject. Connects repeaters via internet using VoIP. Not for websites, DX spotting, or signal measurement.
Memory Aid
"IRLP = Internet Radio Linking Project. Think 'I'RLP = 'I'nternet 'R'adio 'L'inking. Connects repeaters via internet using VoIP for worldwide voice communications."
Real-World Application
Your local 2-meter repeater is connected to IRLP. You can access IRLP node 1234, which links your repeater to a repeater in Australia via the internet. You talk on your local repeater, and operators in Australia hear you on their repeater. This is IRLP - it extends your repeater's range worldwide through internet linking.
Key Concepts
Why Other Options Are Wrong
Option B: Incorrect. IRLP isn't for providing website access via radio - that's what packet radio or other digital modes do. IRLP is for voice linking.
Option C: Incorrect. IRLP isn't for informing about DX station frequencies - that's what DX spotting networks do. IRLP links repeaters for voice communications.
Option D: Incorrect. IRLP isn't for measuring signal strength remotely - that's not its function. IRLP is for voice communications linking.
