FAQ:

Q: How does an upconverter work on an SDR?

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.

Q: Is the upconverter rtl-sdr V2 available for sale?

A: The schematic and Firmware for the V2 is also available right now, but it is still under early testing and may change. The board is not for sale, however you can apply to be considered for a free unit if you want to host your own Electrosense node and meet their criteria. If you do not you can still produce the board yourself.

Q: Where does the rtl-sdr connect to the PCB?

A: A the same time they also note that it is possible to get PCB manufacture and SMT assembly done for you for dirt cheap by PCB prototype companies like JLC PCB. The converter board has 4-input SMA ports (only 3 are used) and one output port which connects to the RTL-SDR. The first input port is for the HF antenna input.
