Ed, sounds like your radios are into VSWR turndown from the inability
of the tuner to match at the low end. It could be that the Z at 3825
is going high which a lot of tuners can't handle--or could be very
low, same problem, no match. Try adding some more length to the
dipole if you can and see if it tunes better at the low end. Even if
you only drape pieces down at the ends would help if you can't extend
more horizontally. 73,Bill W0BVR

You, and others earlier on in this thread, have suggested such a
thing. I have that on my list of things to try when the weather allows.
Tnx.
