Listening around on 6 metres this morning and hearing lots of signals all over the midwest.

This totally cracked me up.  Engineers are a wild bunch, eh?  :) http://youtu.be/dXaFngyVkG4

Yesterday, thanks to my friend Eldon WA0UWH  I had an opportunity to do a little welding both on steel and aluminum.  I have not done any we...

Here is my function for determining an appropriate set of divisors (HSDiv and N1) given the desired output frequency that keeps the Si570 DC...

So, if I have learned nothing else, it is that I am no mathematician and am really slow at figuring out this stuff.  Here is where I am at w...

While I certainly didn't intend to write a novel on the topic of Si570 programming, it is a topic that at least for me is unclear from d...

In thinking about alternative methods of calculating the necessary parameters for the Si570 frequency setting elements, other than double pr...

As previously mentioned, I held two possible interpretations of the datasheet regarding what is meant by how far the DCO frequency could be ...

The relationship between the various frequency setting elements is described as follows: As previously mentioned, the output frequency i...
