+## Download Nightly Software Build
+The [nightly](https://github.com/DSheirer/sdrtrunk/releases/tag/nightly) release contains current builds of the software 
+for all supported operating systems.  This version of the software may contain bugs and may not run correctly.  However, 
+it let's you preview the most recent changes and fixes before the next software release.  **Always backup your 
+playlist(s) before you use the nightly builds.**  Note: the nightly release is updated each time code changes are 
+committed to the code base, so it's not really 'nightly' as much as it is 'current'.
+
 ## Minimum System Requirements
 * **Operating System:** Windows (~~32 or~~ 64-bit), Linux (~~32 or~~ 64-bit) or Mac/Linux (64-bit, 10.14 or higher)
 * **CPU:** 4-core

-Auto-generating Java code from SDRPlay API using jextract.
-
-Note: the api headers in the 3.11 folder are equivalent to the 3.08 headers.  The only
-difference from the 3.07 headers is the addition of the boolean 'valid' flag to DeviceT structure.
-
-1. Download JDK19 compatible build of jextract JDK: https://jdk.java.net/jextract/
-2. If generating on windows platform, modify the sdrplay_api.h to remove the windows
-   pieces of the file.  Specifically:
-2a. Comment out these lines but leave the *HANDLE typedef:
-
-//#if defined(_M_X64) || defined(_M_IX86) || defined(_M_ARM64)
-//#include "windows.h"
-//#elif defined (__GNUC__)
-typedef void *HANDLE;
-//#endif

-//#define _SDRPLAY_DLL_QUALIFIER __declspec(dllimport)
-//#elif defined(STATIC_LIB) || defined(__GNUC__)
-//#define _SDRPLAY_DLL_QUALIFIER
-//#endif
-//#endif  // _SDRPLAY_DLL_QUALIFIER
-
-2b. Remove the '_SDRPLAY_DLL_QUALIFIER' from in front of the method declarations
-
-2c. Change the 3.11 version string to 3.08 either in the header file, or in the generated java class
-
-3. Open command prompt to the root source code where the generated files should be placed:
-..\SDRtrunk\sdrplay-api\src\main\java
-
-4. Generate the code:
-c:\Users\Denny\Downloads\jdk-19-ea2-panama\bin\jextract "C:\Users\Denny\git\sdrtrunk\sdrplay-api\api\v3_11\sdrplay_api.h" -l libsdrplay_api --source
-
-5. Do this for all versions of the API.

 /**
- * Logic Trunked Radio (LTR) 300-baud FSK decoder is designed to operate against an 8 kHz FM demodulated audio stream.
+ * LTR decoder designed to work with 8 kHz input audio samples and decode 300-baud signalling.
  *
- * This decoder employs a zero-crossing timing error detector with adjustable symbol timing error gain.  This decoder
- * also employs a synchronization monitor that automatically adjusts symbol timing error gain according to the quantity
- * of successful message sync pattern detections.  This is optimized for LTR signals that periodically transmit idle
- * bursts and transmit continuous message streams during voice transmissions.  The synchronization monitor adjusts to an
- * aggressive gain value when sync is lost and automatically reduces timing error gain as successive sync pattern
- * detections occur.
+ * This decoder monitors the incoming sample stream looking for either a positive or negative sequence of samples where
+ * the energy delta across the baud period exceeds a threshold value and causes the symbol state to flip.  The symbol
+ * state remains across successive baud periods until the next state change sequence is detected.
  *
- * FM demodulated sample buffers should not be filtered prior to this decoder.  An internal DC-removal filter coupled
- * with a low-pass filter removes any tuning offset and/or audio components above 300 Hertz.  The DC removal filter is
- * adjusted for a slower offset removal in order to prevent overly distorting the FSK signalling component.  This mild
- * adjustment may not fully compensate for mis-tuned signals and may result in missed decodes of idle bursts.  However,
- * the DC filter will track a mis-tuned signal to baseband quickly upon a continuous transmission.
+ * Valid LTR messages start with a zero symbol and transition to a positive symbol for the sync bit, this decoder
+ * monitors for excessively long sequences of a one symbol and forces the symbol state back to a zero.
