[RFI] RT-21 rotor controller RF problem

[Tim Duffy K3LR]

Hello Jorge:

I have 22 RT-21 controllers at my station. We have never had RFI problems -
either to the RT-21 or RFI from it - with full 6 bands of multi transmitters
in operation.

You may have a problem with your rotor on your tower (which is why the RT-21
operated in fail safe mode), not the RT-21.

Subject: [RFI] RT-21 rotor controller RF problem

Hello,

 

Last weekend during WPX contest I had a problem when turning my rotor with
the Green Herron RT-21 controller.

 

It have a feature that start slowly (4 of 10 level) till it reach the full
rotation speed (10 of 10).

 

When I wanted to turn with the “point and shut knob” to the right, it start
at 4, 5, 6   and didn´t reach the 10 level, it stopped turning. This didn´t
happens when I turn to the left.

 

So in the contest sometimes I needed to use the CW button to rotate it to
the right instead the “point and shut knob”

 

Absolutely no winds that cause it to stop.

 

Today I went to the station and the rotor worked 100% to the left and to the
right, so now I am thinking it´s a RFI problem during WPX contest

 

Any idea how to solve the RT-21 RFI problem?

 

Thanks,

Jorge
