Using the naming you are using, logically AND Q11, Q12 and Q13. That's pins 1,2,3 of the 74HC4060. The wiring I gave should be right.

Apologies my my start/stop Posts in this Thread - I find the time when I can!
I got to the stage where I think I understood connecting the output of Pin 15 (Q9) of the 74HC4060 (which is 4.8kHz) to Pin 2 (CP) of the 74HC161 which should deliver an asymmetric 300Hz from Pin 15 (TC) but I experienced severe instability problems with this set up.
So I decided to splash out another 30 pence and purchased a CD4081 to try TonyDuell's alternative approach. While I just about grasped the required pin connections detailed in Post #61 above I don't quite understand why I have three outputs from the 74HC4060 - Pin 1 (Q11), Pin 2 (Q12) and Pin 3 (Q13), to three inputs on the CD4081 - Pin 6, Pin 2 and Pin 1 respectively?
Labouring the point, sorry
but I always like to know what I'm doing and why?
