Here is a much cheaper and better way, which is really not much more difficult:
You can use the same method (Test record with 1KHz test signal) with a laptop and a free downloaded spectrum analyzer. I feed the signal from my phonostage into my Macbook.
Spectrum analyzer is iSpectrum. You can put a marker at 1KHz that displays the signal in dB at 1KHz (so no notch filter needed). You can toggle iSpectrum between left and right channel so that you can easily measure the crosstalk in dB.
For example, you measure a signal at -30dB in the left channel and the crosstalk at -66dB in the right channel giving you a crosstalk separation of 36dB. You minimize the crosstalk just as for the Fozgo meter.
This method is free, only requires a RCA to mini cable to connect to your Laptop and the signal is more stable as you can choose different averaging method with iSpectrum. Another plus is that you see the frequency played from LP displayed in the spectrum analyzer so can finetune the speed of the turntable as the signal should be direct at 1KHz.
This method safes you both the need for a the Fozgo + KAB spectrum analyzer. Let me know if you have any questions.
