To answer your question, lets browse the code for answers...

Looking at program:
trunk/mythtv/libs/libmythtv/hdhrsignalmonitor.cpp<http://svn.mythtv.org/trac/changeset/15437/trunk/mythtv/libs/libmythtv/hdhrsignalmonitor.cpp?old=9729&old_path=trunk%2Fmythtv%2Flibs%2Flibmythtv%2Fhdhrsignalmonitor.cpp>it
appears that the signal strength was hardcoded to 65 - and was changed
to
45 in changeset 15437.
