So glad I found this forum. Over the years I have measured my phono cartridges using spot frequencies and manual analysis. But thanks to the JP script :)it is now a lot easier. After a 'crash course' on python over the weekend I was able to use the script and here is my first post:
My first attempts showed 'strange' results with the amplitude plot of one channel appearing as the crosstalk channel. But then I realized that the script expects the 'main' channel to be the 'top' trace (L) and I had to swap channels for the right channel recordings.

The STR100 record is 3rd edition and fairly new, but unfortunately a bit warped. The turntable is Pioneer PLX1000 and the MP-100 stylus has in the order of 100h playtime. The frequency sweeps were recorded with Audacity (on a Mac) without use of the built-in high pass filter of the preamp ( ART DJPREII ) but subsequently filtered at 25 Hz 48 dB within the Audacity software

Use one of the others as template. Important to write the cartridge name as the first line in the post (more easy to search).
