Re: Experience using rx_power

rx_power will give you dBfs, not dBm, like SDRuno does. Have you used the Power/SNR to CSV function in SDRuno? We'll also be duplicating the CAT command that currently returns dBfs to also return dBm, so automating measurements with a CAT program might suit your need? Best regards, Andy I've tried ...
