I used a 9.75 GHz satellite LNB from Europe and an RTL-SDR to get a 618 MHz downconversion from a 10.368 GHz DRO test oscillator.
I got some ideas from G4JNT: http://www.g4jnt.com/PLL_LNB_Tests.pdf
| Nice peak at 618 MHz on the RTL-SDR with GSDR on the Mac. | |
| 10.368 GHz DRO with attenuator | |
| It says 10.360 but it seems like it was 10.368 GHz. | |
| LNB hooked to DC Block for output to RTL-SDR, and straight to power supply. There are two F connectors, so I didn't put in an RF choke on the PS and it worked anyway. | |
| Power supply 12.17VDC | |
