It's a long time since I read the book on Loran A, but that's what I remember.
So multipath will tend to 'smear' the pulses, but I suppose a good operator
could possibly reduce the effects. Still, if the multipath was always that bad
via skywave, SS Loran wouldn't have worked at all.
Roger, how long were the Loran A pulses? I remember the prf was somewhere
betwen 16 and 25Hz, with different chains on different PRFs, allowing several
chains on the same channel.
