What are you using to power your watt meter?  I tried a friends speech 
plus speaker once and when I hooked to my normal supply that powered the 
radio and so forth, I had terrible rf in the speaker.  The solution was 
to power it off of a separate 12v wall wart and it was clean as a 
whistle.  If you don't already, try running the tw1 on its own supply.
