BETTER YET:
Cut the antenna for about 3550 kHz.
Calculate how much shorter each leg will be for resonance at 3800. (abt. 4
feet).
Mount the end insulator of each leg 4' from the end of the wire.
Drill a hole in a 2 wooden or plastic clothes pins (the ones with the
spring/clip) and mount them on the ends of the wire.
For CW, just let them hang down.
For SSB, fold them back along the antenna leg, twisting a little and clip
the clothespin onto the wire.
This is how I always built my 80m antennas. Most of the time I work SSB,
except for CW contests.
Unfortunately at this QTH I can't do that. Impossible to get at either leg
of the antenna.
Instead, I use the 238B.

I like Stuart's idea of adding some length to the antenna. Don't know why I
had forgotten that back in my novice days I had an 80 meter dipole inverted
"v". Running an HW 101 that I got from N4NT. When I upgraded to general I
just cut about 3.5 ft off each end. Gave me a good match on 75. Put me a
couple of alligator clips on those pieces and when I wanted back on CW I
just went out and clipped the wires back on to the ends, letting them hang
down. Worked great and no tuner.
Best antenna I ever had was 132 ft flattop fed with ladder line. Think I'll
try to slip some ladder line back into the shack.
Thanks to everyone for the advice.
