The DSP setting is a SW tweak of TX level while TX level item 3 works
directly on the CM119x in either selected linear or log modes. The DSP
level is set to 999 by default. Most would leave it where it is and use
item 3 but in some situations you might need finer resolution and then the
procedure is to set item 3 TX level to just higher than perfect and adjust
the DSP level down to match exactly. It is very doubtful that anyone would
do this or need to do this that did not have a fairly accurate way to
measure deviation. It was mainly put in to satisfy repeater operators using
service monitors. In operation you want to keep the DSP level as high as
possible using it for fine adjustment and using item 3 for coarse
adjustment.
