    Great Circle.

    I read something on Navlist that reminded me of duty above 67 North.
    When I first came aboard a new ship, the QM'S used 214 for finding the direction of radio stations for the ships directional antenna. this was a task that took a little time out of a busy watch. Some time the bearing was in question and would be recalulated. The antenna need to be within a degree or so to get the signal.
    After a while I started to get an idea that was my first step toward my two minute Star Finder. I did this with the Rudy you can too. I first place the horizon disk at my LAT&LONG them I placed the transfer Arm for plotting and marked the LAT&LONG of the station and read off the great Circle station bearing. The good thing about this was the accuracy was well-with-in reception and the ship location and antenna was easy to check. The Distance could be estimated by reading height above the horizon subtraced from 90 times 60nm. I now show this in class when I have time because you can look at the bearing and get a good idea as to the Great Circle bearing. where and when. I just use my 2 minute and plotted these reading. 37N &71W to 0North & Greenwich00WE.
    2minute read 102 13ALT 249 101.7/15ALT. Off 120 NM
    That is not unusable but an example. try it with the Rudy, it works. but not with Navigation,After all it was 120NM off.
