+# Introduction
+
+The Detector app is based on the Level app and allow you to get quick signal detection on Lora, Remotes, Tetra UP.
+It will loop as quickly as possible, and if a frequency match the threshold, it will produce a beep.
+
+# Controls (on the top of the app)
+
+First line:
+- LNA,VGA,AMP,Volume: adjust with rotary encode. Volume is the beep volume.
+
+Second line:
+- Preset selection. 
+
+Third line:
+- Bip: rotary encoder adjustable threshold for level detection.
+
+
+# Preset details

+## Remotes
+        // Around 315 MHz (common for older remotes, key fobs in some regions)
+        // Window centered on 315 MHz, covers 314.625 - 315.375 MHz
+        315000000,
+        // Around 433.92 MHz (very common for remotes, sensors, key fobs globally)
+        // Window centered on 433.92 MHz, covers 433.545 - 434.295 MHz
+        433920000,
+## Lora 
+        // EU433 Band (Europe, typically 433.05 MHz to 434.79 MHz)
+        // Scanning the approximate range 433.0 MHz to 434.8 MHz with 750kHz steps
+        433375000,  // Covers 433.000 - 433.750 MHz
+        434125000,  // Covers 433.750 - 434.500 MHz (includes 433.92 MHz)
+        434875000,  // Covers 434.500 - 435.250 MHz (covers up to 434.79 MHz)
+        // EU868 Band (Europe, typically 863 MHz to 870 MHz, specific channels around 868 MHz)
+        // Targeting common LoRaWAN channel groups (approx 867.0 - 868.6 MHz) with 750kHz steps
+        867375000,  // Covers 867.000 - 867.750 MHz

+        // US915 Band (North America, typically 902 MHz to 928 MHz, specific channels around 915 MHz)
+        // Providing a few sample windows around the 915 MHz area with 750kHz steps.
+        // This band is wide; a full scan would require many more frequencies.
+        914250000,  // Covers 913.875 - 914.625 MHz
+        915000000,  // Covers 914.625 - 915.375 MHz (Centered on 915 MHz)

+
+## Tetra UP
+        // Band starts at 380,000,000 Hz, ends at 390,000,000 Hz.
+        // First center: 380,000,000 + 375,000 = 380,375,000 Hz
+        // Last center:  380,375,000 + 13 * 750,000 = 390,125,000 Hz (14 frequencies total for this band)
