This means that PowerSDR S-meter readings currently are in error on 50 MHz and when used with VHF or UHF transverters. Until and if this discrepancy is corrected in the PowerSDR software, we must remember to add 3.3 S-units (20 dB) to the PowerSDR S-meter reading in order to give accurate S-meter reports above 30 MHz.
