Access to Receiver Profile data

I am trying different home brew 1090 Mhz antennas and I would like to analyse the difference in performance (max. positions, max. messages/sec, directions and so on). The Receiver Profille data is a very good guidance for that. But this is only available on My Opensky.
I would like to download the data of the Receiver Profile page to do my analysis.

(I tried the Opensky API, but this show only the current state vectors. I needthe statistics like mentioned above. And I can download the graphs in several formats, but not the actual data).

Is there a way to download the original data of the Receiver Profile page?

There is no official way of downloading the receiver profile data and therefore there is no official documentation for the API endpoints your receiver profile uses. Since most data isn't transmitted as key - value combinations, but as nested arrays, I'm afraid reverse engineering will be hard to impossible.

Best,
Marco
