Yes. Also, when first experimenting with them, I tried the higher 
bandswitch setting for both. As I recall, I could make 17M work on 
either the 20M or 15M setting. Perhaps the same on 12M. Don't 
recall, but my operating notes to myself, based on that testing, 
says to run 17M on 20 and 12 on 15M.  

BTW -- two of the three units I have can be run at greatly reduced 
drive level (about 8W) to put out 200W on 30M, and I do that 
occasionally when chasing a rare one. The bandswitch setting that 
works best is 40M. The oldest of the three (VERY early production) 
won't work on 30M at all. Behavior suggests that one of the bandpass 
filters is preventing it.
