The last alpha version of CubicSDR now include Hamlib. This will allow an SDR device to be used as panadapter for a transceiver. Here the signal is picked up via the G4HUP PAT. Setup it’s really easy.
I’ve just changed the switching voltage regulator with a ST L78S05CV, that it’s rated 2A, and some capacitor. Now also the VLF band is noiseless.
