This section is part of DSP-10 User's Manual Chapter 1 V396 - Transceiver Operation


Some commands are only meaningful when the lower waterfall display is being used (see Alt Y command.) The spectral display is not used with the Slid-Rule dial and requires no controlling.

Once the graphical front panel appears on the computerscreen, all operations are controlled by keyboard entries. There are no mouse driven operations. Note that the Scroll-Lock key affects commands. Most commands will not respond if the Scroll-Lock is on,but you must have this on to exit the program . No 'unmodified' keys are used for commands, which leaves  the standard keys available for sending CW or the various weak-signal modes.
The band change commands that use the Ctrl-Alt modifier are dependent upon the definitions for the various transverters. This is done through the configuration file "tvtr" lines. If you use the default configuration file (or no configuration file at all) you get the defaults. All others are undefined until you add a line in the configuration file, and will generate a warning message if you try to select them.
What follows is a concise, but complete summary of available commands from the keyboard. Note that nice summary sheets, such as the one by Jimmy Oldaker, W7CQ are available over the Internet.
 The following list also includes links ,which will open in a new browser,  to information in this manual with more detailed information on the commands.
