Which of the following is a way to establish contact with a digital messaging system gateway station?

  1. ASend an email to the system control operator
  2. BSend QRL in Morse code
  3. CRespond when the station broadcasts its SSID
  4. DTransmit a connect message on the station's published frequency
Why Digital messaging gateways such as Winlink RMS stations publish their operating frequencies and mode in station lists, and you reach them over the air by sending a connect request (for example a packet or ARDOP/VARA connect) on that frequency. The gateway is automated: it answers the connect frame and then negotiates the link, so no voice or CW calling is involved. Your software just needs the gateway's callsign and its published channel.
Watch out Emailing the control operator is backwards, since the whole point of the gateway is to pass your email over radio, and QRL in Morse simply asks whether a frequency is busy. Gateways do not broadcast an SSID for you to answer; an SSID is only a suffix that distinguishes multiple stations under one callsign.
Look up the published frequency, then send a connect request. Radio link first, email later.
