"P. Venkman" wrote in message
om... "Highland Ham" wrote in message ... Here's an idea. How about talking to the senior radio technician on the military base? Just maybe he/she would have the answer. ================ Or borrow a handheld scanning receiver. It could well be that a nearby transmitted signal ,not necessarily on or near 'your ' transmitted frequency affect the RC receiver (which probably has limited immunity in respect of strong harmonics/mixing sigs.) Frank GM0CSZ / KN6WH I appreciate the replies, but the problem is NOT with the receiver, it's with the transmitter. I admit this was more or less the response I expected, but I really hoped someone would say 'oh, I had the exact same problem and designed and built a filter for my transmitter that fixed everything, and I'd be happy to show you how to do the same'. But thanks for the replies, I do appreciate it. Look, if the transmitter is "synthesized" i.e. not crystal bound, and it is suffering the problem only near the Military base, then it is pretty obvious that the transmitter is being overwhelmed by a stronger signal. IT CAN AND DOES HAPPEN! The minute signal of your transmitter milliwatts to a watt or so is most likely being swamped out by the mega watts they are using or the mixing of the signals is doing it. Either use a crystal controlled transmitter there, or quit flying there! They're not going to shut down for you to fly your model plane. You claim that is the only place it happens.... Sooooooo! Maybe no one else flys in RF bombarded fields to have experienced the same problem that you're looking for the answers to. The answer is obvious. Crystal controlled or stop flying there. Lou |
