[Elecraft] Where To Start??

Hi Bill,

The Spectrogram program version 5.1.7 is still available as freeware at this
site:
http://home.t-online.de/home/on6et/page7.htm
(scan down the list of progs)

It's a very neat little Windows program that is user friendly.  You just
need to connect from
the headphone jack or the external speaker jack (with a stereo plug) to the
Line or Mic input
of your PC sound card.  I connected the two-conductor cable right across my
head phone terminals
so the phones still work. Then plugged into the Mic connector and after
adjusting the volume,
it took right off.  Spectrogram initially came up with the sensitivity set
to 60db. At first my volume was
too low and I didn't see anything until I set Spectrogram to 90 db. Then I
got orientated and it was very
easy to use after that.

You can play around with the sample rate and the number of samples to
control the horizontal resolution.
I usually use 16 bits and 44K samples/sec.

You do need a noise generator; there are schematics on the net. These are
small circuits and construction
is not critical (it's supposed to be noisy, right? :)

I found Spectrogram to be a terrific program for aligning the filters and it
provides insight into how
the filters actually work.  It's also good for checking the adjustment of
the VFO frequency. You can see
the signal from WWV and tune it right in (in CW mode) using a marker
corresponding to your
sidetone frequency.
