  1. AM voice, FM voice, and SSB
  2. Packet radio, IEEE 802.11, and FT8 ✔
  3. Analog TV, AM voice, and FM voice

Why: Packet radio sends data in packets, IEEE 802.11 is a digital networking standard, and FT8 sends digitally encoded messages. All three qualify as digital communications.

Huh, didn't know that: A digital mode represents information with coded symbols rather than a continuously varying signal.

The dad joke
The digital modes counted on each other. They were all binary buddies.
