Any one in the group had experience of the BaoFeng UV-5R in general or on the birds,the spec looks good, as does the price, but that's not the whole story is it? Regards Robert G8ATE
I had a 5500 azmith rotator lockup over winter. I finally had time to take it down and find the problem. Now a different problem. I forgot to mark the housing position before separating the upper/lower azmith assemblies. I think I know where it was pointed, but how can I tell where it should be aligned? Is this really a non issue?
Hi Floyd, KC5QBC
With the upper assembly separated from the lover part of the rotor rotate the azimuth motor until the position of the slider of the 500 ohm potentiometer comes mid way i.e. 250 + 250 ohm i.e. until it will show the same voltage of about 3 volt betwen terminals 1 and 2 and terminals 2 and 3
Terminal 2 is the slider of the potentiometer i.e. is the cursor.
Now mechanically mount again the upper part of the motor hood midway betwen both limit switches.
It's all you have to do to get again the calibration between the potentiometer and the upper part of the assembly.

Hi Floyd,
Domenico's advice is quite good. I also wrote a section on aligning a g5500 az rotator from scratch, its at the bottom of this post:
