Figure 5:  Using the radio's front panel, whether a real radio or a PC screen, you can spin the dial on a virtual or real band but also command a remotely controlled radio. A propagation switch is set to desired band conditions where 1 simulates tough 160m conditions and the DX position opens 20m for solid 48-hour two-way contacts. A simplex / duplex switch is needed since many traditional operators may prefer talking in turns (simplex). A mode switch between public and private may serve the purpose as well.
