I have been listening to some excerpts from a book on the KE9V podcast
(Long Delayed Echos)
that has caught my interest:
Calling C Q,: Adventures of short-wave radio operators
by Clinton B DeSoto (Author)
I am interested in buy an edition or a reprint if I can track one down.
I started prepping the EEE laptop for Field Day.
Here is a picture of the desktop with Writelog running on XP.
I still need to test the K2 interface along with the K1EL keyer. It looks pretty promising
so far.
The last major item is determining how I am going to power the laptop. it is a 12
volt laptop so I need to see if I can run it directly from a deep cycle battery or
if I am going to need a regulated power supply. I need to plug it into a DVM and see
what the numbers show.
OK.... it is time for me to get back into the VHF contest again. (I typed this while
eating lunch.)
OK... that is looking much better!
My friend Craig AA0ZZ was able to give me some valuable insight. I need to zoom into
quite a bit in the time domain to be able to see the sine wave otherwise it just looks
like blurred noise. Once you zoom into the time domain a bit you can see a nice oscillator
as you might expect.
Then I was able to right click and select the waveform (source data) to show
in the FFT display
I have to say that this looks pretty cool. There is a lot of magic in this application.
I have some other examples that I want to build to see how they look/work. I am such
an electronics newbie that this is all uncharted territory for me.
Here is an interesting little transmitter. I found it while searching for oscillator
information.

Ok... Now I am seeing something that resembles RF from an oscillator.
I had to enable Small Signal AC Analysis.
Then I had to configure the AC Analysis Option
Now that I have some notes in the blog I can come back here to try to remember how
I made this work last time. :-)
Hmmm... my 40m oscillator from the example does not seem to be making noise where
I would expect it to.
It is clear that there is a lot here that I do not understand. :-)
