I bought a 300W unit on sale at Target for about $30. It produces a
loud buzzing sound throughout the RF spectrum. I kept it, because
I figure it will be good enough to check into an emergency net on
75 meters, but I wouldn't consider using it in a contest to
receive weak signals. I think there are some expensive ones
available that produce a true sine wave. That type should be ok.
