Hello all!me again with the gated freq gen.i manage to solve the tiny problems on Stans skematic all working good i get a controlable square wave coming out of the 9xa at 1,2,3,freq ranges and outputing the 74ls122 on pin8.BUT the problem is at 4th frq range(the one coming out directly of the 555 cip),i get a week distorted signal and is not controlable by the 74122.My thoughts are:
1.the 74122 cannot handle other waves than the square ones ,and pin3 of the555 does not output a perfect square wave.
2.I tried hooking up 2 more pots for freq adj. and when i let all 3 of them at minimum i can see and control the wave with the 74122,when i raise the freq the signal gets distorted again.
So what can i do?Is there any electronics GURU on this forum that can help me?i strugle with this circuit for over 5 monts,i cannot start any experiments with the coils because of this... i am going CRAZYYYYYY.....Thanks in advance!
