Hello, i have a new rotor with Preset. If I have the VOX on, while the rotor is running the radio is activated. I think is RF, instead the antenna is OK. Any idea how to solve it? keeping the VOX on

Do you hear hum or some other noise from the rotor in the mic audio? I would guess some kind of grounding problem in the rotor, maybe putting AC on the mic or keyer line. David Robbins K1TTT e-mail:

Thanks Perry and David, I did a few more tests and seems the problem is when i use the MFJ-434 Voice Keyer. In CW no problem. And when I connect the Heil Pro Set direct to the radio also no problem.

What kind or rotator controller ? Is it doing some kind of PWM (pulse width modulation) when it starts and stops the rotator, that is inducing EM fields in the MFJ voice keyer ? How close is the rota

Hi Steve, Prosistel control (original with PST61D rotor). From control to MFJ-434 is 1 feet. I disconected the ground from MFJ-434 to get it longer from controller and no problem. Seems the problem i

This sounds similar to a problem discussed many years ago about hum induced in receivers by the TailTwister T2X rotor controller when the brake solenoid was activated. As I recall, the "quick" soluti

I have a big wire (maybe AWG 1 or more) under ground to the shack. From there a AWG 8 in the back of the desk with singre wires to each radio, amp, rotors, antenna selector, etc. For now the problem

Hi Mike, Rotor cable and coaxial from antennas came together under ground from tower to shack. I will add some split beads before it is connected to the rotor control box. 73, Jorge CX6VM/CW5W --Mens

I would guess the problem is not coming from the rotor control box, but from the cable (Or power cable) coming out of the box acting as a antenna. Try separating the rotor cable from the other cables
