Kitted the QSD

The Quadrature Sampling Detector that I found has been kitted.

I know what parts are on the QSD but I don't have the schematic yet.  Soon, I hppe.

The main thing is I think I have the part-list (BOM) made and on order.

So once I get the schematic, then I can start to stair-step my way towards a QSD that might work.  It might not work but that's part of the fun too -- to figure out what he heck is supposed to happen.

Knowing how I do things I'll probably end up trying many different designs for a QSD and end up with different versions of something that will teach me.

The difficult part to find was BF545B, SOT-23 since it is longer made.  But the data sheet had the clues to find a close work-alike JFET.  I think so at least.  I'll experiment with the part in isolation to see if those choices were correct.

SDR.   Seek Device Replacements.

No QSO, no Donut

On the very last day the cafe was open, they sold the special donuts -- one had to pre-order them.  I got one of the last "Jam Filled&q...
