         And possibly the most misleading.  ARRL changed their 
methodology for measuring IMD around 2007 by using a 3 Hz BW spectrum 
analyzer to separate IMD effects from phase noise effects.  The human 
ear has ~50 Hz bandwidth at best  so their results are very 
misleading and not comparable to earlier ones listed on the same 
chart.  If you want meaningful (i.e. what you will hear with your own 
ears) results that are comparable over time stick to Sherwood's summary.
