<p>Hi Take,</p>
<p>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.</p>
<p>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'.</p>

<pre><span lang="EN-US">I believe you have already have the answer to the question of RedPitaya</span>’<span lang="EN-US">s categorization arguments. RedPitaya has 2TX x 2RX on a single board and therefore it exceeds Hermes and ANAN-100 which has 1TX x 1RX on a board. I guess multiple Hermes board configuration can support 2TX x 2RX or even 3TX x 3RX but I do not know the details and I believe you can explain.</span></pre>
