Details Latest release of PSR-500/600 "CPU U1.7" Firmware has been released.

CPU Production Firmware Version 1.7 release notes:

- This is the user loadable version of the Factory 1.7 CPU firmware
  which will display as "uP Appl Ver:U1.7" after loading and is
  identical to the factory "uP Appl Ver:F1.7" firmware.

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

New features:

 * Changed S-E GLOB "138-174 5kHz:" item to "Bandplan:", with choice
   between USA and Canada

 * Changed step size to 12.500kHz in 405.987500-512.000000MHz range
   when the “Bandplan: Canada” option is selected in the FUNC-GLOB
   menu.

 * Change stepsize between 470.000000MHz and 512.000000MHz
   from 12.500kHz to 6.250kHz to handle the new UHF bandplan


Fixes / Enhancements:

 * Further qualify EDACS "Individual" call grants to address a
   problem where the radio sometimes tunes to MDT transmissions as
   radio-to-radio calls.

 * Fixed EDACS "channel number" in CCDump messages


Other:

 * New DSP Boot code V1.1 to handle a different Flash IC version.
   There is no user-noticable performance change.
