At 3.5MHz, the SWR(50) of an 80m dipole cut for resonance at 3.8MHz
could easily be 12:1 or higher. Depending on the length of the coax,
that can present impedances at the tuner that will be well outside the
matching range of a 238.

Thanks for the advice. The antenna is the old dipole fed with 8x coax. I did
have a doublet up that was fed with ladder line in the past and it was great.
Wife just doesn't like the idea of me cutting a hole in the wall to get the
ladder line out of the shack.
My tuner matches great transmitting on 40 with the 80 band dipole. Where I
have the problem is tuning the dipole that is cut for 3800 down into the CW
portion of the band. I just can't seem to find the combination. I'll try your
suggestions and watch the meter closely as I may be missing the sweet spot I'm
looking for.
Again, thanks for the advice.
