Features
SDR up-converter/receiver shifts low frequencies up by 100 MHz. Used to listen to HF frequencies on an inexpensive RTL-SDR module.
- SBL-1 mixer
- 100 MHz can oscillator
- Low pass filter
- 1 kHz to 1.7 GHz SDR Receiver - WA3TFS Design
Software
Build
- Nice silver mica caps
- My kit was missing the center cap of the band filter (150 pF)
- 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
Enclosure
- Board fits perfectly in
