1 KHz Sine Wave

Am I the only one who can't see the images on that page?

EDIT,, ok, maybe he has just deleted the early example pictures.

That's interesting, I also want to do a frequency counter where the input
is a buffered sine wave, and both for the same project!

It has undergone some transformation since I got it

Must be, I can see pictures & tables & code, lucky link for me as I was wanting an example in C for a lookup table. Check your ADBLOCK & script blocker settings, maybe you're blocking the images from there. . . I would say it's a safe bet that radio was old when you were born, what is it?

Yes, but when I'm dead, it's going to be newer than that
There is another box that ends up going under this, to interface with it,
but without any new chassis holes (i.e.. nothing that can't be reversed.



It's the most ambitious for me yet.
RF probe frequency counter to display the LO frequency minus the Intermediate frequency for
digital station display, and then later, feedback to turn the original dial with a low geared stepper motor.
It is difficult to introduce a new micro or PSU, into an AM radio.

Your lookup table in C is the same as using a PBP array.

byte[36] of the static declared array is index 35.
The size you declared the array, you start counting from one like a Human,
but when you go to address it, it's back to programming, and you count from zero.

Don't know what to say... Old tube radios have analogue components, and unstable oscillators
Will have to do the Huff Puff technique to stabilise it with analogue components.
This is not yet fit for a robot tuner.

Kinda got a rule about completing projects, and number of simultaneous projects!
