Are you putting the signal in through the power supply?
Doesn't seem they are being skeptical as much as they are just being asshats.

Dave used batteries also.
Could you explain some things? Are you saying there is not only 55.5kHz but also it's harmonics at 111kHz ? sorry but I couldn't understand few words on your video probably due to accent
Or maybe you wanted to show Us that there is something injected to the signal through a ground loop of the probes ?
It's not my video
Just found it on YouTube.
As I understand it he says that it also modulates at 111hz at 111khz carrier ie twice Daves frequency. 55khz could be the fundamental frequency or another harmonic, still not convinced that there isn't some sneaky business going on but it's beyond me, just have to wait for Dave to come clean or someone to crack it........watch this space
Quote from the video author found on youbtube :
If he has done it like me, than there is a hidden wire to the control voltage pin, from an external sine generator, adjusting the level with another? pot outside the camera view. Of course, if you add a capacitor from this input to ground, the modulating signal will be shorted :-)

That makes sense, so it/s not just the frequency which changes, varying the voltage on pin 5 also varies the duty cycle which can be detected with a simple RC filter.

I found this slightly amusing:
One person: I want to know what brand solder flux that guy is using and how much he's inhaling.
Another person: Holy jeez, I know! He is rather obnoxious.
I do not detect any extra wires going to the breadboard, but I notice that Dave is working on top of a thin mat. So I am going to suggest a loop antenna underneath transmitting the 55.5Hz signal. With the cap missing, the breadboard spring would need to pick up well enough to put a few tens of mV swing onto the control pin (which is connected to the 5k-5k divider internally).
Dave must be reading too much of 'Harmonic 695'! Maybe time to get out our tin foil hats

I get comments like that all the time!
They wouldn't now what enthusiasm is if it bit them on the arse.
Dave.
Can we get a Detail Sketch (all the values and where you took your measurement).
I am new to electronics and just got myself a oscilloscope and I can't get the same wave form as you did. Sorry n00by speaking.
Very interesting 1/2 second or so at about 2:15 are those wires to the bottom of the bread board? aerial?
Yep! Looks suspiciously like an aerial coil or a pair of wires to me, could be just a wire clipping but the breadboard seems to be stood on some sort of mat. Makes me suspect some sort of magnetic loop or rfid type of thing (running out of ideas so any straw looks good
)
Just listened to the latest AmpHour. Definitely sounds like you nailed it FreeThinker!
Good thing Dave doesn't work for the CIA/NSA/FBI.
Check out my video response
www.n1ir.com . Breadboarded multiple times multiple chips and still could not get it to oscillate? Watch video 7 and see me build it up. Might be a ground loop or picking up the mains (50 hz) all I can think of?
