This version (DD_SYNTH v1.30) for the EME85B does the following,
1)      Fixes a bug that could infrequently cause the display to "lockup".
2)      Adds the option to assemble the program for either the PIC 16F84 or 16F628.
3)      Adds the option to use either the AD9850 or AD9851 DDS chip.
        (the AD9851 can use 1 x refclk or 6 x refclk)
4)      Adds the option to include a REPEATER TX offset function. 
        Requested by Cristi Simion - YO3FLR.
        When the new RPT button is pressed an extra -600 KHz or +600 KHz offset is added
        to the TX frequency. The default REPEATER TX OFFSET is 600 KHz, but it can be changed
        in the RPT OFFSET setup screen.

This package should include the following files.

Readme.txt      This file.
DD_Synth.asm    The main program source file.
DD_Synth.dat    This file contains options and settings that the user may want to change.
DDS_F84.hex     Hex file for programming a 16F84. 
                (Option 0 used in the DD_Synth.dat file, AD9850 DDS, no REPEATER TX function)
DDS_F628.hex    Hex file for programming a 16F628.
                (Option 6 used in the DD_Synth.dat file, AD9850 DDS, no REPEATER TX function)


                Note:- If you want to use the AD9851 or the REPEATER TX function you will have
                       to edit the DD_Synth.dat file then re-assemble the DD_Synth.asm file
                       using Mpasmwin.
                       Assembling the DD_Synth.asm file with any of the options will always
                       produce DD_Synth.hex, the two hex files above have been renamed
                       to avoid confusion.
