jittery servos, strange problem
I have a rc sailboat using a futaba 29 MHz radio and the servos are constantly jittering when the transmitter is not really close(a couple of meters, the range of transmitter is over 160 meters) but if I turn the transmitter off the servos stop jittering so I am confused as to what this means and where the problem might lies.

How is the antenna routed? Away from the servos? Near any other electrics? Near any static sources such as metal parts that could be rattling in the wind?

Have you tried it outdoors with a simple range test?
Under the right conditions, there may be some interference generated inside your house. When mixed with the signal from your transmitter the procucts result in the jittering you see.
Try a collapsed antenna range test out in the open. Very likely all is well.

Tried the open range test, no different. Also I see no interfering signals on my sdr which lets me look at all the radio signals on my computer screen. At this point I will have to try swapping different components in and out of the system to try and track down where the problem originates, I had just hoped to narrow things down with theory before trying this but that doesn't look like it is going to happen so on with the task.

I am using 4 aa 1.2 volt nimh batteries for the power which I actually worried might be too low as the receiver is a bec type. The whole rc system is quite old, it is what came with the 2ndhand boat, I have installed a new electrolytic capacitor in the receiver but that made no difference to the problem.
