DL2MAN (tr)uSDX vs QRP Labs QMX+
Home / Comparison / DL2MAN (tr)uSDX vs QRP Labs QMX+
DL2MAN (tr)uSDX or QRP Labs QMX+? I put both radios side by side: data from the manufacturers’ datasheets and photos at the same scale. The DL2MAN (tr)uSDX comes out better: spectrum and waterfall, transmit current draw and weight; the QRP Labs QMX+: power on 6 m.
