[GreenKeys] W2PAT TU

[Jim Haynes]

The W2PAT design was the first TU I ever built, except I think I got
toroids from somewhere rather than using TV width coils.  I have a TU
in the basement now that is most likely a W2PAT, does use width coils.
Whoever gave it to me said it was a Twin City TU, but it isn't.  The
design was published in QST in January 1953.  I had a PSK QSO with
W2PAT a few years ago.
