I'm not really confident about your display, because the source is sweeping very quickly. It's probably shifting 25 to 50 MHz in 1/240th second. (The frequency sweep one way and back in 1/120th second).
When I was playing w/ MOs, I used a standard gain horn, cavity wave meter, crystal detector, and scope. You may be getting something like aliasing between the scope sweep and the maggie sweep. -John =================== > Hi > > Unless I'm missing something on that display, there are multiple peaks > within 10db of the biggest one.
