[aprssig] Displaying Operating Frequency

That's a neat idea..... I have my wife's car's tracker set to change modes
when the GPS is off.  It changes from a car to a runner.  There would be no
difference in using a PIR motion detector in your ham shack set to a 10
minute on time tied to the mode change pin on a tiny trak or open trac.
