Finding a open radio frequency

Just trial and error. Depends on you location. Find an empty station preferably with dead air on either side. Drive around your street and check it's really empty a few blocks away. The check again in the evening as radio waves sometimes bend more at night and more distant stations may appear. Check over a few nights. Car radios are usually pretty sensitive for checking with.

From reading this I'm guessing that your problem is not a lack of an open channel, but rather that your own transmitter is transmitting a distorted signal. The most common cause of that is that you are over driving the transmitter. Reduce the output level from your computer and see if that helps. BTW, if your transmitter has both a mic input and a line input, you almost certainly need to be using the line input.

If the radio you are listening on is fairly close to the transmitter, you should have no issues with other signals causing you problems. That is a simple test to see if your problem is an interfering signal or your own transmitter.

I had the output volume on the xmitter on high which caused the static. Once I turned it down and went back to stereo instead of mono it works good. Stupid me but what else is new. As Scrooge says in the musical version of his movie I've always been stupid.
