Bob, John, and the gang,

I agree. 

Why the palstar can’t match at 1.825 and the Ten Tec 253 can, yet the palstar can easily match the doublet at 10.120 and the 253 can’t
still remains a mystery to me.

I did notice that when I added the extra feed line and extended the antenna length, the palstar previous setting are now way different. I don’t know how the roller inductor is calibrated i.e., does 200 mean more L or 200 Less ? I don’t know.

Without the wire extensions, 40 and 30 meters came in with a L of 79 to 83, but now, they are 170 to 190.

I have a half-dozen antenna couplers, all from Ten Tec and will swap in a few to see what happens.

The quest continues….

I know they should be the same, but experience the problems you describe with a wound balun at times.  The problems are not there with a sleeve balun.  And, sometimes the sleeve had problems but the wound one doesn't.  A choke balun is another thing to try.
