My problem remains... I did remove the faulty volt converter that was transmitting strange signals... But when doing range check on the field it seems the problem remains. I am not sure now if the converter was faulty, maybe it just enhanced some signal that is faulty from the beginning in the receiver. Now I dont know what is wrong. I have opened both transmitter and receiver and by just looking at the condensators and leads they look fine. I also tried moving the crystals and exposing the systems to slight vibrations - nothing. I will have to go to the store with my radio and change crystals or receiver... very irritating, sometimes I whish I bought a 2.4 Ghz system
