I haven't been checking every message... but has anyone noted that what is 
driving it could be the problem?  Tuners act as a rather narrow bandpass filter 
in most cases so if the radio/amp driving it is generating a harmonic or 
parasitic that varies as it warms up the swr measured will increase.
