[K6BW] Interesting project description of a homebrew 2-meter FM receiver

[Bill Smith]

Stolen from QRP-L

Below is the introduction and link to Nick, WA5DBU's FM receiver experiment.
He is using "dead bug" construction which describes turning all the parts
upside down and connecting their "legs" together to make a circuit.  It
isn't very pretty, but it works.  If you look at the assembly picture, you
can see round pads of circuit boards mounted on the main copper-clad blank
circuit board.  The pads are used as tie points.

"After buying one of those Si570 synthesizer boards by WA6UFQ (the one with
the same form factor as the NJQRP DDS boards) and seeing that it will go to
160 MHz, I thought it would be fun to do something on 2 meters with it.
Another thing that's been interesting me is projects using chips like the
MC3362, intended for VHF FM, as ham HF / CW receivers.  So I figured I'd try
the chip more in its intended use first.

First I needed to program the Si570 to provide the LO required for a 2 meter
superhet with a 10.7 MHz 1st IF.  Programming that thing is pretty wild,
you've pretty much got to take up Numerology as a religion.  But I've got my
Arduino board set up to do it.  I got it working, it's pretty cool, and now
I can put a check in that box and do something else.

It's all documented here on my web page, complete with scandalous photos and
a schematic.  BTW, this was my first try at doing a schematic with the
ExpressPCB software.  Thanks NA5N for the component library and step-by-step
instructions posted in this area recently."
