DRO (dielectric resonator oscillator) LNB types have very poor frequency stability and are suitable only for the reception of wide bandwidth carriers, such as a 27 Msps satellite TV or VSAT outlink carrier, where the receiver tuning circuits can lock onto the carrier despite frequency errors of up to +/-500 kHz or +/- 2 MHz and second's delay (or more) locking up is of no consequence.

PLL (phase lock loop) LNBs use an internal 10 MHz crystal oscillator (which has high stability) and a phase locked oscillator at say 10 GHz. Frequency accuracy is very good (say +/-25 kHz) and phase noise is low. Use this type for the reception of low symbol rate carriers and higher order modulation carrier like 8PSK and 16QAM.

Hello, good morning. I think Prisa Catalunya's signal strength has been reduced again. I haven't had a signal for months, not even at night when it's cool. Is anyone else experiencing this? Thanks.

You wouldn't have found Prisa Catalunya on 12552 H, because it was moved to the new slot-12534 H, 783, 2/3.
