C
Three digipeater hops are requested with one remaining
D
Three internet gateway stations may receive one transmission
Answer Notes
In the APRS (Automatic Packet Reporting System) protocol, routing is determined by the packet path. The 'WIDEn-N' format is the standard syntax for wide-area digipeater routing.
The first number, 'n', indicates the total number of hops originally requested by the transmitting station. The second number, 'N', indicates the number of hops remaining before the packet stops being repeated.
Therefore, WIDE3-1 means that three hops were originally requested, and there is one hop remaining. Distractors mentioning stations on frequency, subcarriers, or internet gateways fundamentally misunderstand the APRS store-and-forward digipeater routing syntax.
