[AMRadio] One pic is worth a thousand...

[CL in NC]

If any of you are scope pattern interpreters, I hope you can give me a read on a pattern that I have on both an AF67 and AF68.  With the TX keyed, the unmodulated trace on the scope has both a bright carrier displayed of 3cm, inside or superimposed on  a dimmer carrier display of 5cm.  There is no ultrasonic oscillation in the audio stage that could generate this, and it is not a scope retrace.  Is this an indication of a fundamental carrier freq, the darker trace,  along with a harmonic of lesser power and higher freq, the higher freq making a brighter pattern?  Or nothing?  I do have a pic, but can't attach it here.
