Hi Joe, MF
the last nights I have been testing various antennas and receivers on MF.
1. ELAD FDM DUO with RF systems DX-1-------only local OP8 decodes
2. ELAD FDM DUO with Wellbrook ALA-100HG-----only local OP8 decodes
3. SDR-IQ with Wellbrook

The ELAD can´t handle the Wellbrook loop, it is allways clipping (ADC
overload) even with a 10dB attenuator in front.
