Detailed Description of Figure 3
The image simulates an actual transceiver. The analog S-meter in the upper left corner includes a needle that registers signal strength (and fluctuates in real time). The code keyer speed and pitch controls are below the S-meter. The microphone gain knob is at the lower left corner of the panel. The VOX level and dwell controls are to the right. Next to those a small label indicates the transmission mode, which is Push to Talk, selected using the Mode button to the right. The Squelch On/Off button is above the Mode button. The AF Gain control is in the lower right corner of the panel.
Above the AF Gain is the Sweep button, which sets the number of channels displayed on the bandscope. Text on the Sweep button indicates that 100 kHz is selected. The Tuning knob is at the upper right corner.
The bandscope extends across the top of the panel. A digital readout shows the transceiver is tuned to 7.138 MHz. With the sweep width at 100 kHz the bandscope baseline consists of 100 channels between 7.088 MHz and 7.188 MHz. Small vertical lines in three of the channels indicate they are in use. Text in the bandscope gives information the transmitting ham has chosen to display, shown here with his permission: "M0SAL-Douglas, Birmingham, England. Registered Blind, 76 years old."
Six different Band Selection buttons are arranged horizontally under the bandscope: 3.6, 7.0, 14, 21, 28, and 29 MHz.
