Hi All
I'am having some probs with a if amp that uses a mc3372 chip.
There is a crystal osc on pin1 and pin2, i'am trying to read the
frequency of the oscillator to make sure that it is 10.245Mhz.
I used a 10x probe on my counter and read 10,24258Mhz on pin 1,
(base of internal transistor), but on pin 2 (emitter of internal transistor)
i get 10.695Mhz but it is jumping around, up to 10.815Mhz, it's all over
the place.
Anyone got any hints as to what might be wrong ?.
Regards
Howard
