Helmut,

Ok,  I understand your understanding about RedPitaya though I have different perception.

Thank you.

Hi Take,

Pse recall: the Redpitaya is a third-party product. To run it under OpenHPSDR software, once Pavel Demin wrote an emulation of the HERMES firmware for the RedPitaya's Xilinx-FPGA. While Hermes employs only one physical frontend (ADC), but capable for multiRX (which is mandatory for the used PS algorithm), the RP uses its second ADC for PS-feedback. Due to the absense of a second ADC with coherent sampling clock HERMES can't provide the diversity function.

Due to the different FPGA codes and the RP emulation I would suspect, either you can use PS as 'Hermes clone' or diversity as 'ANAN100D-clone'.
