[TowerTalk] Yaesu 2800DXA

[Steve Jones]

Wayne,
Years ago I had an AC powered rotor 800 feet from the shack.  The voltage drop was too much over that long run of wire and the motor wouldn’t turn.  I added a 5 VAC filament transformer (or was it 12 volts?) in series with the motor lead leaving the shack to boost the voltage.  It solved the voltage drop problem.  
Is there a way to boost the DC voltage at the RT21?  Copper's not cheap.
73,

 Likely the current draw in colder weather is dropping voltage below rotor requirement.  So, I would increase the wire to 2x14 and 6x18.  I got mine from Wireman.

 I  have a Yaesu 2800DXA rotor on my 40/30 antenna. It’s rotor length to the antenna is  390 ft.

I am using the 6 conductor 18 ga on the tower 80  ft.  and  2X16 ga and 6X20ga  with two  extra wires added  one to  CCW and  one to CW motor control.  B MY issue is  during the winter below 30 deg. F. many time to rotor will not turn in that cold  WX

The control  box  is  ab Green Heron RT21 ???    bigger wire to the base ?
