Thanks Andrea,

locator calculations were derived from the wwl package. It turns out wwl 
produces negative results sometimes:

$ wwl jn54ql re66hl
qrb: -1499 kilometers, azimuth: 93 degrees

We can simple add half the circumference of the earth, which gives us 
the correct number, so in wwl.c we can add a line like:

        if (p < 0) p = 20002 + p;

line 217 in wwl.c
