There is not a range switch on the TW-1.  It will give some kind of voice
reading at a few tenths of a watt, although I would believe it starting at a
few watts.  When set to generate a tone, the pitch barely moves at a couple
of watts, once the tone starts, and goes up by almost a musical fifth at 100
watts.  I've never driven it with more than 140 watts, so don't know what
the pitch is at higher power levels.
