RF test

After all the RF connections ready, a transmit test needs to be made. First, set a frequency in the band you will operate most the radio (Eg. 6200 kHz). Then two tests should be carried:

Voice test with the microphone, for microphone and its button operation check
Single tone test, for establishing the power level of the radio

In order to log-in to the HERMES User Interface (UI), a default password is set (that can be changed), and it is:

user name: root
password: caduceu

To enter the voice screen in HERMES UI, follow the Figures 2.31 and 2.32.

**Figure 2.31:** HERMES UI with a finger pointing to the voice functionality icon.

**Figure 2.32:** HERMES UI in the voice screen.

The expected result of the voice test, when talking with normal voice level, should be the wattmeter having a oscilating power level, ranging from 0 to 40W.

In order to carry the single tone test, enter the radio configuration screen, as shown in Figure 2.33. The single tone functionality is enabled using the “PTT” button in the radio configuration page, as shown in Figure 2.34.

**Figure 2.33:** HERMES UI with an arrow pointing to the radio configuration icon.

**Figure 2.34:** HERMES UI in the radio configuration page, an arrow points to the “PTT” button.

The expected result of the single tone test, should be a power reading of approximatelly 20 W, as shown in Figures 2.35 and 2.36.

**Figure 2.35:** Confirmation question shown after clicking to enable the PTT. No power.
