Using WiNRADiO

When you first start WiNRADiO, you are presented with a radio receiver interface. The

image below shows the main parts of the control panel.

The following few sections document each of the parts in detail.

Basic Controls

Frequency Readout

The frequency readout shows the current receiver frequency.

Below this is another display which shows one of the following:

the callsign and/or a comment relating to the current tuned

frequency, taken from the frequency memory (entered by the user), or the description of the

current band. The band description is user-definable under ‘Auto-stepping’ in the Configure

menu.

To enter a frequency, simply type the desired frequency using the keyboard. As soon as you

press a number or the decimal point, the frequency readout will enter the edit mode, allowing

you to enter the frequency. The old frequency is automatically overwritten. If you want to

edit the existing frequency, click on the readout with the left mouse button to highlight the

current frequency, position the cursor as desired, reclick the left mouse button, make the

desired changes, then press the Enter key. To change the frequency unit (kHz, MHz or GHz),

press K, M or G respectively while the display is highlighted or in edit mode.

To tune the receiver to the new frequency, press the Enter key. To cancel and return the

previous display, press the Escape key.

In each mode, the frequency readout only displays the most significant digits which affect

tuning and reception. The display resolution is as follows: 1 Hz in CW, LSB and USB, 10

Hz in FMN, 100 Hz in AM and 1 kHz in FMW.

In FMW, the lowest tunable frequency is 30 MHz. If you attempt to tune to a frequency

below 30 MHz, the receiver will automatically change the mode to AM, and disable the

FMW button.

Tuning Knob

The tuning knob adjusts the frequency by the smallest suitable increment for

the current mode. In LSB, USB and CW it is 10 Hz; AM is 100 Hz; FMN is

500 Hz, and FMW is 50 kHz.

To use the knob, position the mouse cursor over the top half of the knob, and

the cursor will look like this: . To decrease the frequency, click the left
