Hello all
I have a th5 at 45 feet and generally have no problem finding its
direction by a simple method - peaking the station which I want to work.
Further, if the band is open the change in noise level is a good
indicator, particularly on 10 M.
If I want to point to a given direction and I don't currently know the
direction, I wind it totally to the end stop one way or the other, then
time the rotation. As 360 degrees takes a minute, then very simple to
convert seconds into degrees.
This method is, of course, not very satisfactory, but I can see two
solutions.
1. The feed back from the rotator to the control unit has three lines,
earth, left and right (clockwise or anti clockwise). If a VCO is placed
across these then no problem converting to direction with a bit of
calibration.
2. Their are some parallel port driven antennas which you can drive
from some logging software - one of these is a modern solution.
