An SMW or Norsat PLL LNB might do the job, even some of the newer domestic PLLs aren't too bad. <a href="https://satellites.co.uk/forums/threads/newsnet-on-ka-band-a.161382/page-29#post-1111792" target="_blank">This post</a> shows the effect of high phase noise on a lowish rate 8PSK signal. You can see that as I improved the phase noise, by changing the synth reference, the angular spread reduced and the SNR improved. You could check your LNB by looking at a strong low SR signal and comparing the constellations to those in the post.</p></blockquote><p></p>
