+## 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

 /**
- * 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.

+ * Digital Coded Squelch (DCS) demodulator/decoder designed to work with FM demodulated 8 kHz input audio samples and
+ * decode 134.4-baud signalling present in the unfiltered demodulated audio stream.
+ *
+ * This decoder monitors the incoming sample stream looking for either a positive or negative sequence of samples where
+ * the slope of these values exceeds a threshold and causes the symbol state to flip.  The symbol state remains across
+ * successive baud periods until the next opposing slope state change sequence is detected.
+ *
+ * This decoder uses a slope detector to decode the 134.4 bits per second stream and identify the DCS code.  It is
+ * designed to work with 8 kHz audio sample rate.  Each baud period is (8,000 / 134.4) = 59.52 samples per symbol and
+ * a full DCS tone sequence is 23 bits * 59.52 samples/bit = 1369 samples.  The DCS tone sequence is continuously
+ * transmitted at a rate of 134.4 bits-per-second / 23 = 5.84 repeats per second while the source continues transmitting.
