Hi, Bob:

Tks for the info.

Would you be kind enough to specify any limitations to your encouraging 
opening statement, pls?

Btw, I was unclear about important physical arrangements.  The coupling 
between the catenary and the vertical was capacitive, and the catenary 
formed the curved top bar of a " T " with the vertical.   The catenary was 
arranged to have equal lengths either side of the vertical; symmetrical, if 
you prefer.

Using "adjust" in place of "tune" is fine by me.  The end result is the 
same, I think.

TIA & 73, Dave, N3HE
