Mauri,

The top trace shows periodicity at a 6.5 MHz rate. Since
the signal has a Fourier component at this frequency, if I
pass it through a low-pass filter with a cutoff at say 7 MHz,
I should get a clean 6.5 MHz sine wave (e.g. Fin/2).

[Dave, do you have a spectrum analyzer, or can you hear
the 6.5 MHz signal on a receiver?]

Mike, W4EF............................
