Jan --

    Here's something else to try.  After taking benchmark SWR readings (and
on the air tests if possible), rotate the TH7 90 degrees so that the booms
are at right angles to each other.  While the Cushcrafts don't seem to suffer
from the same problems that the KLMs did with interaction with the booms
inline, again it might be an interesting test.  

     BTW, Dave's, K6LL,  comments about trying different lengths of coax did
wonders for my KT34XA on 15M.
