@ -3,7 +3,10 @@ This App Provides a view of the spectrum over a very wide range of frequencies.
The frequency ranges are held in the SD card >LOOKINGGLASS>PRESETS.TXT. It should be noted that the size of the frequencies should be keep small to limit the memory use.
# Key Controls
* MIN / MAX: Place the cursor on the “MIN” or “MAX” fields and use the rotary encode to select the frequencies for the MIN and MAX frequencies in increments of 240mHz. The Label “RANGE” shows the scan range set.
* MIN / MAX: Place the cursor on the “MIN” or “MAX” fields and use the rotary encode to select the frequencies for the MIN and MAX frequencies in increments of 'steps'. The Label “RANGE” shows the scan range set.
* Range value: place the cursor over the range value and click to lock/unlock the range when changing MIN/MAX.
* Gain: Gain Setting: Cursor can be used to select and adjust the LNS(IF) (0-40), VGA(0-62) and RF AMP “0” (off) and 1 (14dB).

* MARKER: If you place cursor over the field and turn the rotary encoder a red marker arrow will appear on top of the cascade so you can see approximate idea of the frequency for each pixel. The interval of the marker that is changed by the encoder knob, is shown and is based on the scan range. If you press the encoder know or Button then it will take you to the Audio App for more detailed view of the signal with setting of 1mHz Steps and a 10mHz view. Unfortunately, on return to the LOOKINGGLASS App the display goes to default settings.
* RES: The field can be changed by the rotary encoder to select the resolution (FFT Trigger point) (2-128). The default setting is 32. This allows the display to show better the Signals received and should be adjusted in conjunction with “Gain:” and “FILTER:”

* STEPS: This field can be changed by the rotary encoder to select the step size used when moving the tuned window.
* STEPS: This field can be changed by the rotary encoder to select the step size used when moving the tuned window / when moving one of MIN/MAX.
* SPECTR/LIVE-V: This field can be changed by the rotary encoder to select spectrum scrolling view (default) or the live frequency power level view.
* S-/F-: Slow but more accurate scan / Fast but less accurate scan.
* 3x: integration multiplier field, only shown if LIVE-V is selected. Ranging from 1x, the quickest integration but with noises and spikes, to 9x, the slowest integration, but more clean and no spikes.
* SPECTR/LIVE-V/PEAK-V: This field can be changed by the rotary encoder to select spectrum scrolling view (default),the live frequency power level view, or the peak frequency level view.
## Additional LIVE-V / PEAK-V controls
When switching on one of these mode, one more filter button 'x0 to x9' and one more line of widget are added: 'MAX HOLD: VALUE <RST><JMP>"
* x0 to x9: integration multiplier field, only shown if LIVE-V is selected. From x0, the quickest integration but with noises and spikes, to x9, the slowest integration, but more clean and less spikes.
* RST: reset the most powerful detected frequency and clear the screen
* JMP: Jump to audio app on MAX HOLD detected frequency
