Dear Barry,

When I bought my first C. Crane FM Transmitter I had the same problem
you do. A call to a technician at C. Crane "fixed" the problem. The
range is adjustable. The "label" on the back is actually a "door" to
the inner workings. If you "peel" it off, you will see the adjustment
screw. Turn it all the way (to the right, as I remember) and you'll be
amazed at the range. I don't remember all the particulars as this was
several years ago. I have purchased a couple of new ones recently and
the range was at maximum on receipt.

Hope this helps.

Best,

Joe
