Same grid must be used for UA0T, as I get same bearing & distance from here
in OL72bk. UA0W is apparently QTF 185 at 11093 km, with ascending &
descending earth turns of 2304 & 1231, respectively. UA0S/T are at 1512 &
0510, though only 1000 km further away at QTF 166.
One suggestion: if a station has a grid in TRMASTER, then one only gets a QTF -
no range or sunrise/sunset times. It would be nice if the program could
use that
grid to calculate all, as it does for just the prefix of a call in the call
window.
