Narrative:
Before departing; a local a&P cleaned off the alternator which resolved an electrical generating problem. The alternator was generating power; but instead of continuing on to our original destination; I decided to return to [home airport]; so the plane's normal a&P can take off the alternator and decide if further maintenance was required. During the flight; the generator failed again; or there was a different issue with the radios. I tried calling the tower using both the hand-held radio and the plane's own radio; neither worked. I squawked 7600; entered the airspace; flew over the field and entered a left downwind for landing.
