AR-IQ III software operation AR-IQ III interface: 6-1 Frequency tuning 6-1-1 Frequency tuning with mouse wheel Tuning with mouse wheel while hovering on the digits of the frequency indicator panel. The digit of the currently tuned frequency will be shifted upwards or downwards depending on wheel rotation direction. Example: Let’s say you are tuned to 101.756 MHz and you hover the mouse over the third digit “1”.
- Page 10 6-1-2 Frequency tuning by ten-key input Double click on the marked frequency indicator panel to display the ten-key • window. This allows direct frequency input. Enter the desired frequency by clicking on the digits of the ten-key, including the • [.] if necessary.
- Page 11 6-1-5 Frequency tuning with the secondary spectrum window Allows to fine-tune the filter passband in 3 modes: PBT, NOTCH and AMREJ. a) PBT mode (Passband tuning) Centers the carrier frequency you have double clicked on the secondary spectrum. Press the left mouse button while dragging left or right does retune the center frequency.
- Page 12 6-2 The main spectrum / waterfall window Displays the spectrum with a bandwidth of up to 900 kHz. (+/- 450 kHz around the center frequency). You can chose between spectrum view and waterfall view. (Main spectrum view) (Waterfall view) 6-2-1 Wheel step This is the value by which the spectrum will be shifted by scrolling the mouse wheel, when the mouse is hovered anywhere over the spectrum or waterfall.
- Page 13 6-2-2 Frequency tuning by double click on spectrum It is possible to “visually” decide to which frequency you would like to tune the receiver by double-clicking directly on the spectrum or waterfall. The minimum resolution is 1 kHz. 6-2-3 Frequency tuning by mouse drag on spectrum Note: CENTER button in TUNING panel must be unchecked.
- Page 14 6-2-5 Frequency tuning with “center” button OFF With this setting, the spectrum remains fixed, whereas the yellow tuning dial will jump to whatever frequency you double clicked on the spectrum. This mode is convenient if you want to search through frequencies between a fixed start and end frequency.
- Page 15 b) Color palette Here you can decide which colors are displayed depending on the signal strength. Not active for regular spectrum view. c) FFT resolution The FFT sharpness (spectral resolution) can be improved at the expense of refresh rate. This function is particularly useful when analyzing strong carrier signals and carrier feed-through on adjacent bins has to be reduced at minimum.

7-1 Recording To record, first select the center frequency of your choice. Click on the record button at the bottom left of the window. A new window pops up asking for a user defined file name and folder location to store the file. For ease of use it is advised to create a file name which includes the date, such as 180622 for June 22, 2018. - Page 19 to repeat a possible station ID over and over again. A left click on the line cancels the new selection, and continues playback normally. Troubleshooting: If the user fails to create a new line, but only "clicks" to attempt to advance playback by a few minutes, the software may seem to "stick".
