[amsat-bb] Yaesu G-5500 az issue

[Norm n3ykf]

If that's (clutch) the problem, a replacement from Yaesu was not
available (call as this may have changed).

I got a pinion gear from a micromachine shop over in England. Like $15
including shipping. Not an exact fit, but very, very close.

The load (antennas) need to be well balanced for this to work. Motor
won't start a pre loaded gear train.
