  I am very happy to announce a Loran-C receiver for STM32F407 !
  This is the very first beginning, expect monsters inside.

26.01.2014, Matthias Koch, Loran-C 0.2:

  Coarse initial frequency calibration without frequency counter
  Convolution with pulse shape in assembly
  Pulse train detection algorithm
  Signal Quality and Time Delay calculations
  Convolution based algorithm for on-the-fly frequency tracking
  Example signal for Sylt and Lessay chain
  
09.02.2014, Matthias Koch, Loran-C 0.3:

  Pulse envelope peak is now assumed to be on 65 us -
  this has been on 72.5 us before, an historical value
  Quickstart binaries included which already contain all Forth sources
  Automatic frequency calibration should work now even
  when pulse trains all have same amplitude.
  Signal detector implemented
  Glossary available
  Paul Swed did a lot of testing with a Loran-C simulator

17.02.2014, Matthias Koch, Loran-C 0.4:

  Faster interrupt handlers
  Changed memory map to make longer GRIs up to 93500 us possible
  
26.02.2014, Matthias Koch, Loran-C 0.5:

  Longer time for measure the frequency offset shift should
  give a more precise frequency calibration
  Quickstart binary now also contains hexdump and disassembler
