Comments from a newbie to FTA

Swapping in the GeosatPro SL1PLL to replace the Invacom didn't change things for receiving WPR. I can receive WPR well on the V9 Prime with either LNB. But I can only see an indication of a signal but no lock on WPR with the Edision Mio+ using either LNB.

Even with said LNB, isn't a receiver capable of
tuning lower symbol rates and more precise frequencies still required?

Yes. It is a combination of a capable receiver and frequency stable LNB. The AFC process for most tuners is quite adequate, but the minimum SR handling is the limiting factor. A PLL LNB teamed with an external TXCO reference source will provide the best stable signal for decoding.

Unfortunately, aging Invacoms have proven to be quite thermal frequency unstable.
