FAQ:

Q: What is an rtl-sdr upconverter and how does it work?

A: In order to listen to frequencies below 24 MHz an upconverter is required (either that or perform the direct sampling mod). An upconverter works simply by shifting these lower frequencies up to a higher frequency that the RTL-SDR can receive. For example, a 5 MHz signal might be upconverted to 105 MHz.

Q: What is the best RF upconverter for SDR?

A: Ham It Up v1.3 Barebones – Nooelec RF Upconverter for Software Defined Radio. Works with Most SDRs Like HackRF & RTL-SDR (RTL2832U with E4000, FC0013 or R820T Tuners); MF/HF Converter with SMA Jacks

Q: What is the lowest tunable frequency an rtl-sdr can receive?

A: The RTL-SDR’s lowest tunable frequency is 24 MHz, and so it can only receive a small portion of the interesting transmissions that occur between 0 – 30 MHz. In order to listen to frequencies below 24 MHz an upconverter is required (either that or perform the direct sampling mod ).

Q: What is the upconverter nano?

A: Upconverters enable SDRs that cannot tune in the HF bands to receive HF by shifting the low HF frequencies “up” into a range receivable by most VHF/UHF capable SDRs. In his latest video Techminds reviews the Nano together with an E4000 tuner based RTL-SDR with built in bias tee.
