not sure what i should be seeing there, but I don't think that looks right.

Edit,
What you said about " the number of stripes will decrease and they will get broader. If you get close to zero beat (meaning the oscillator frequency is close to the burst frequency),"
an am not seeing this, They roll up,/down but tuning the coil for the osc, never made them decrease/ get broader, they did stop moving at one point...

which makes me suspect it's off freq. ( a guess )
so when i saw this...

it was too good to pass up,
it may not fix anything... or, who knows...
