To be more specific . . . my former Ham IV motors (too weak for my 4 EL Stepir)
and my current Yaesu G-2800 both fit the TX-472 rotor mounting area w/o
interference in crank-up/down. However, for example, a Hy Gain Tail Twister
will not fit and allow full crankup/down of the tower. So, what rotator are you
using? - Alan K9MBQ

>>Hey guys,
>>
>>
>>
>>I have a US Tower 72 ft crank up. I just put a Steppir DB36 with NN4ZZ's
>>Tilt Plate on it. I cranked it up to vertical & turned on the motor to raise
>>it to 72 ft. The motor turns a few times with the tower not moving up & then
>>grinds to a stop. I haven't climbed up to see if I left anything stuck in
>>the tower to keep it from moving. I feel like the problem of that is pretty
>>slim.
>>
>>
>>
>>Let me add a few more details that my give a hint to the more knowledgeable.
>>The tower has been tilted over on its side for abt a year. A couple weeks
>>ago, after I had the Tilt Plate & Steppir connected, I discovered I had put
>>the rotor (located inside the tower) on, turned so the cable connection wud
>>not clear the tower when it telescoped up. I had to run the tower out abt 6
>>ft with the Steppir on it so I cud get to the rotor & turn in.
>>
>>
>>
>>Any thoughts, suggestions wud be most appreciated.

>>73,
