W1FB Rx Project

This sweet little receiver is based on a design I found in one of W1FB's QRP Notebooks. I made the VFO external and inject it into the SA612. I also incorporated varactor tuning

This is my first attempt at "Manhattan" Construction. You can see the original W1FB schematic in the background. Notice the "internal" VFO circuit...

....an overall layout, still have more parts to install. Note the double-sided tape waiting for it's toroid.

...the pads are made using a sheet-metal nibbling tool. Got to tell ya, I'm really liking this method of construction!

...can you see the surface mount zener diode???
