============================================================
CPU Production Firmware Version 1.5 release notes:

- This is the user loadable version of the Factory 1.5 CPU firmware.  
  Will display as "uP Appl Ver:U1.5" after loading and is identical to
  the factory "F1.5" load.

- Please use with DSP version 1.2 or higher, otherwise some features
  may not operate properly



New features:

 * Per FCC approval, changed 700 MHz frequency tunable range to:
   764000000 MHz - 805996875 MHz
   (all on 3.125 kHz steps)

 * Changed 700 MHz ranges in Public Safety Search and Sweeper to:
   764000000 MHz - 766996875 MHz
   769000000 MHz - 775996875 MHz
   794000000 MHz - 796996875 MHz
   799000000 MHz - 805996875 MHz
   (all on 3.125 kHz steps)

 * Added "connect tone" display to M36 analyze mode, alternating
   with other data (QQ% SID:xxxx Syy).

 * Added "OmniLink" 6-char site name to M36 Analyze mode alternating
   with other data (QQ% SID:xxxx Syy).

 * Added "RadioIDAlert" item to FUNC+GLOB menu. If set, then we'll
   show the private TGRP's alert when:
   a. showing a group call.
   b. showing the private TGRP's tag on line for for the radio ID.
   c. private TGRP's "LED Color" is non-zero (the default 'off').
   d. new menu item enabled.


Fixes / Enhancements:

 * Fixed missing 'DG' display for digital trunked VCs (bug that
   was introduced in F1.4).

 * Fixed P25 CC analyze problem with system ID info (bug that was
   introduced in F1.4).

 * Added timeout to trunking analysis results in TUNE mode, so 
   spurious false detects (esp. Mot 3600 low-speed) won't cause
   persistent display of trunking data.

 * Fixed issue where occasionally, pressing MAN while in SCAN mode
   would not go to the last active object.

 * Fixed problem when multi-scanning some EDACS systems.

 * Swapped Source vs Target Radio IDs in handling of EDACS
   "I-Calls" per customer reports.

 * Un-swap (version 1.4) source and destination radio IDs when showing a
   Private Call Wild Card where the source ID was locked out.

 * Fixed search modes possibly skipping a freq while paused, if 
   zeromatic is turned on.  While waiting for unmute delay, we were
   checking zeromatic even if paused.

 * Added additional qualification to storing polled P25 NAC. We
   only store it if:
    the new NAC is non-zero, OR
    we don't already have a NAC value, OR
    the NAC value we already have is zero


Other:

   For users that have VHF trunked systems which utilize 5 kHz 
   centers, the following changes were made:

 * Allow 5 kHz steps between 138 MHz and 174 MHz.  These are 
   enabled with a new menu item in FUNC+GLOB.
   If not turned on, use the 'normal' steps.
   If turned on, 5 kHz steps are used in ALL modes.
   CONV objects created in one "mode" will tune based on the
   "active mode" - that is, if you create a CONV object 138.005 MHz
   with the feature enabled, the radio will tune to 138.000 MHz if
   the the feature is not enabled (although 138.005 will be displayed)

 * Changed default receive mode for 138 MHz to 144 MHz to AM if the new
   "5 kHz" feature is disabled in the FUNC+GLOB menu (default).

 * Changed default rx mode for 138 MHz to 144 MHz to FM, if the new
   "5 kHz" feature is enabled in the FUNC+GLOB menu.
