SDR up-converter/receiver shifts low frequencies up by 100 MHz
- Used to listen to HF frequencies on an inexpensive RTL-SDR module
1 kHz to 1.7 GHz SDR Receiver - WA3TFS Design

Nice silver mica caps
Real SBL-1 mixer
Build was tough due to very small pads on the PCB
- Particularly tough to solder ground pads
- Pad shapes were not round so less area to set soldering iron
Pin 1 orientations on the mixer and oscillator "backwards" from other board legends
My kit was missing the center cap of the band filter (150 pF)
