Ali,the VCC for Stans VIC circuit was 12 volts and VDD was 5 volts.The first two resistors are 220k and the cap is 10uF.

OOPS !
my oversight is acknowledged, thank you sir!
I will make the changes and correct...
as far as the cap on pins 6 & 2 i think 1.0 uf makes more sense because it allows a higher frequency for the scanner to lock the VCO in less time, thereby following resonance more closely
Any opinions from anyone else on this?
@Don... ? are the photos you post allowed to be shared with others on the net or do you frown on sharing this stuff ?
thanks for all you did and are doing... our country needs to be free from Oil Addiction ASAP !
EDIT:
fixed the VCC issue
went back to the original 10VDC at the top of the resistor dividers for pin 3 of the LM741 on fig 8 as well, the result was a sawtooth wave with a peak of about 5 volts and a valley of about 2.5 volts. I hope this is what we need for the VCO input on pin 9 of the 4046
see images below regarding the 555 timing
with the scope set at 1 second per division horizontally the difference is very noticeable
I vote for the 1.0uf cap for a closer tracking of the WFC resonance
the 10uf takes too long to charge resulting in a huge delay...
