DSP-10 Change Details
Revisions 3.17 to 3.80

Version 3.50 of the PC program, issued in 2005, added new capabilities over version 3.17,  including:

• Extensive Memory capability. Stored as PC files, these allow changing frequency, mode and almost any other operating parameter.
• FM DTMF tones are available in transmit.
• Tone bursts and CTCSS are available in FM.
• Ending tone bursts are available in SSB.
• Power-to-Tone conversion is available for peaking antennas on Sun or Moon noise (or any other application).
• Help Screens now come from an ASCII file and can be easily customized.
• The Audio Processor now has 1 Hz RIT and full mode capability.
• All screen Saves are now in GIF format.

Version  3.80 had the major addition of automatic clock setting from GPS data. In addition there were many items improved or added. These changes are:

• Time is now always UTC (GMT) and the DOS environmental variable TZ is no longer needed.
• Precise time is retained during returns to DOS. The DOS clock will reflect this correct time.
• Time can be set manually, with NMEA GPS string, or with Motorola UT+ binary data.
• A time-log data file is available to diagnose clock problems.
  
• Screen saves have narrow color bars on the sides of  the top spectral display to show the slicing of the data for the waterfall display.
• The DOS-Visit has been enhanced with file saving of the screen, increasing the available memory for the Visit by over 100K.
  
• The old EME QTH listing has been expanded to also display Earth distances and bearings, based on GPS data , if available.
• QTH data can be entered from a CTRL-U dialog box as either Lat/Lon or 6-digit grid square.
• Number of stations for QTH data has been raised from 10 to 25
• CTRL-Y clears the waterfall display
• Error messages have been added and clarified.
• The F1 help file, UHELP_1.TXT has been updated
• The Beacon Overlay will be stopped from transmit by either the Home key or ALT-H beacon control
• The long  CW/LTI characters ~, { and } will be broken before their end, in response to either a change in beacon T/R state or the Home T/R key. They used to wait until they completed.
• A "Warm Boot" of the DSP is available, primarily for those using the DSPx, when the L/R channels appear reversed.
• The color selection for the bar graphs has been corrected. These are now programmable from the configuration file.
• Several minor bugs have been fixed
