CINF 690 and WRKO

[Dan.Strassberg]

CBM was directional (officially DA-2, but really DA-1) although its
pattern was almost circular (equivalent power behind the pattern--to
the south--was ~30 kW, IIRC). CINW was also nominally DA-2 but
actually DA-1. It sent the equivalent of ~10 kW to the south. You
might call the pattern sort of cigar shaped with maxima to the east
and west. CBF was ND; Like CINW, CINF was nominally DA-2 but actually
DA-1. It sent the equivalent of ~8 kW ND to the south. The pattern was
sort of kidney shaped with a broad, shallow minimum to the south.
