Hello,
Newbie here....
I just got through building the Burst Generator and everything seems to be working fine except for the internal clock. It doesn't seem to be oscillating. I've spent the last 3 hours looking it over & honestly I'm too much of a newbie to even know how to properly troubleshoot this beyond the basics.
-All resistor & capacitor values are correct
-All diodes are oriented correctly (and are the correct type)
-Solder connections have been checked for connectivity between pads
-I am using a 2Meg pot for the internal clock's speed - only two wires soldered, one to the middle lug, and another to a side lug. Both wires are going to the "pot" pads on the PCB
-pin 6 of the 106 seems to stay high all the time
I do have a scope, and I've tested everything out with an external clock and I can see that the main bulk of the circuit is working.
Can someone give me some tips on where to start looking?
Also, can someone please explain to me how the clock works so I can make sense of it for future applicaions?
Thanks,
Jim
