[Elecraft] K3: re CW ID macro on SSB

[Ron D'Eau Claire]

I never mentioned anything about "cheating", Guy. 

 

For example, a model A Ford has a clean simplicity compared to modern cars.
But that doesn't mean they're better than modern cars. 

 

However, modern cars are hugely complex by comparison.

 

The same for radios. 

 

No one here was denigrating modern technology.

What is a "real" CW signal?  One that keys an oscillator?  

 

K3 ain't your daddy's analog radio. 

 

The K3 has the digital number stream elements for a pristine keyed CW signal
in firmware and feeds that into the TX digital to analog converter which
comes out in the 15 kHz TX IF.  That signal proceeds to go through the same
analog amplification string as the SSB signals.  Surely that's "cheating"
too.   A real CW signal would have to be cleaned up by working on the delay
and state change constants derived from capacitors and resistors in the
circuitry, right?

 

The pristine CW signal of a K3 is derived by digital "cheating", since the
waveshape can be derived from a theoretical math curve that no one has ever
been able to make with resistors, inductors and capacitors.  

 

We still got all our perceptual facilities stuck back in the analog muck.
Digital "cheating" all over the place in a K3.

 

73, Guy.
