Hi Ray,
Thanks for the logging of Radio Blackstone.
I was testing an tx with an QE08-200 tube in the endstage but the audio was not good in my opnion.
I changed the tx for a smaller one with the GU-50 tube in the endstage but kept the modulator the same.
This time was the audio quality good and I now know that the problem is with the tx and not the modulator.
Have to look in to tx what the cause could be.

Greetings,
Herman, Radio Blackstone.
