Echoing GTH's post and providing details.  I also saw problems with the potentiometer.  Specifically, when trying to tweak the RF even slightly, the power becomes very erratic, rapidly dropping from 500 down to ~300 (sometimes even down to 0), then jumping back up to 450, etc.  There is also an unusual whining sound (from the drytek, not the user), both when the RF is tweaked and when it is left alone.  This seems to only happen at certain positions of the potentiometer (comes and goes as rotate tuner).
