Hi there,
I'm testing NovaSDR with RTL-SDR v3 dongle. Everything works well in NORMAL MODE (VHF/UHF) but I don't know hot to configure DIRECT SAMPLING MODE for HF.
Any advise? Thanks.

Ok found the additional setting:
> Add SoapySDR device settings? (key=value) Yes
> Setting key (blank to finish) direct_samp
> Setting value 2
