Hmm, this introduces a lot of redundant code. What would you think
about trying to make it a little more automatic?

  for band in ["vhf", "uhf"]:
    for index in range(0, 10):
      key = "test.%ssquelch%i" % (band, index)
      name = "%s Squelch %i" % (band.upper(), index)
      rs = RadioSetting(key, name, RadioSettingInteger(0, 255,
          getattr(self._memobj.test, "%ssquelch%i" % (band, index))

(Note that this is untested, just off the top of my head)

You could do this for squelch and power and save a bunch of lines of
copied code in this patch.

What do you think?
