Question T8C08

From subelement T8 - T8C

T8C08
Answer: A

What is the Internet Radio Linking Project (IRLP)?

AA technique to connect amateur radio systems, such as repeaters, via the internet using Voice Over Internet Protocol (VoIP)
BA system for providing access to websites via amateur radio
CA system for informing amateurs in real time of the frequency of active DX stations
DA technique for measuring signal strength of an amateur transmitter via the internet

Why is this correct?

IRLP is specifically designed to connect amateur radio systems like repeaters through the internet using VoIP technology. Option A correctly describes this core function. Option B incorrectly suggests web browsing capability. Option C describes DX spotting networks, not IRLP. Option D describes signal measurement tools, which IRLP doesn't provide. IRLP creates a bridge between traditional RF systems and internet connectivity for extended communication range.

Memory tip

Look for the key phrase 'connect amateur radio systems' in IRLP questions. The word 'linking' in the name directly hints at its purpose - creating connections between separated radio systems. This pattern appears in other amateur radio networking technologies too.

IRLP transforms local repeater coverage into wide-area networks by routing audio through internet infrastructure. You access IRLP nodes using DTMF tones from your radio, maintaining the traditional amateur radio operating experience while leveraging modern networking. This hybrid approach preserves RF skills while expanding communication capabilities beyond line-of-sight limitations, making it valuable for emergency communications and ragchewing across continents.

Think about it

Why do you think IRLP requires you to use a radio and DTMF tones rather than allowing direct computer access like some other internet linking systems?
