the first thing I would do (per AIM) is squawk
7600. If not under ATC surveillance and not in contact with them, then
I'd likely leave it at 1200, unless I needed to land at a controlled
field somewhere.


You'd better need to land at that controlled field pretty badly
because you'll be busting the regs if you do that. Squawking 7600
doesn't relieve you of the requirement to establish two-way
communictions prior to entering a class D. Of course, if you're low
on fuel or there are no non-towered fields you could divert to, then
you can probably get away with it. If there are alternate airports,
the best thing to do is to land at one, call the towered airport and
get a clearance from them to enter the class D, then expect light
signals. If you're already in the class D when the radio dies, you're
OK. Just proceed and look for the lights.
