As you can see from the photos, this transceiver does not have a tuning "dial." Rather, it uses the keyboard 4-way controller to control the tuning of the receiver. The left-right arrows control moving up and down in frequency, and the up-down arrows control the step size, from 1 Hz to 10,000 Hz. To enable you to keep track of your step size, the display shows small zeros indicating your steps. Thus, for example, a step size of 100 Hz will show two small zeros, as in 7.0300oo, for example. Using the auto repeat function of the keyboard, it is very easy to do a band scan.
The CALL button has 3 states: BLUE = not calling. RED = repeated calling CQ with your call sign. ORANGE = completing the current repeat and then ending the call with a single K for "come back."
Calling is a very simple procedure: Press CALL once to start, press it again to start the ending process.
And then listen for a response!
