Question T4A10
From subelement T4 - T4A
What function is performed with a transceiver and a digital mode hot spot?
Why is this correct?
A digital mode hot spot acts as a personal gateway, connecting your transceiver to the internet for digital voice or data communication. Unlike traditional RF-only communication, hot spots enable worldwide connectivity through internet-linked networks like DMR, D-STAR, or System Fusion. Options B and D describe specific digital modes that don't require hot spots, while option C describes RTTY operation that works independently of internet connectivity.
Memory tip
Think of hot spots as 'internet bridges' for digital modes. When you see 'hot spot' in a question, it's always about extending local RF communication to internet-based networks. This pattern helps distinguish hot spot functions from direct RF digital modes like FT8 or RTTY.

Digital hot spots function like cellular towers for amateur radio, creating a bridge between RF and internet protocol networks. They operate at low RF power (typically under 10 milliwatts) to communicate with your handheld or mobile transceiver, then route your digital transmissions through internet servers to connect with stations worldwide. This enables participation in DMR talkgroups, D-STAR reflectors, or System Fusion rooms regardless of local repeater availability, making digital communication truly global.
Think about it
Why do you think a hot spot uses such low RF power if it's meant to extend your communication range globally?
