transformator in the tb's cpu

[René Schmitz]

Hi Andreas!

The CPU is clocked at 455kHz. (1/2.2uS) That rings a bell - thats IF of AM
radio. Use a bandfilter from an old AM-radio, and experiment with the cap.
One can perhaps use a 455kHz ceramic resonator instead. 
If nothing helps make a small oscillator with the ceramic resonator and
supply either CL0 or CL1 with that signal. You'll have to try which one.

Bye,
 René
