Hi guys of JR

I have a JR SX-600 since 5 years ago. A very reliable radio, that allows to fly in electromagnetic-congested places without interference. But, recently, my radio started to allow several interferences. The radio works, a mean, i have control of the moving surfaces, but only in the very-close range, 4 meters. When i start walking around my plane, the control surfaces starts moving a lot, at same time i can move by myself the control surfaces. I tried to replace the chip located in the center of the radio, from a S400 radio (this radio worked great), but the problem still. I dont want to throw up my SX-600, cause it works better than any of my futaba and hitec, so i need help¡¡¡¡¡ thanks.

actuall radio set: Hitec Supreme receiver, 72910 cristals, tested changing receiver and crystals, but problems persist

Check the antenna connections to the receiver. We have had a couple incidences at our filed where the antenna broke apart from the receiver printed circuit board. Give each, assuming you have two antennas a tug to make sure they are not broken at the PC board connection.

Well, i tested succesfully to fly with another radio- no problems or interference. i tested also an old s400, with good results. So the problem is in transmitter. I cant find what is wrong. Thanks
