Hello,
this is an screenshot of CW-Beacon:
LNB: Megast Diavolo
Ext. Ref 25MHz-TCXO
Adalm Pluto
What is the cause of the phantom signals -10dB ?
I tested a new LNB same type without modification: No phantom signal.
I built an separate input ( not via RX signal! ) for external 25MHz reference but to the C with 330Ohm in series: Phantom signals -15dB
The reception is stable + / - 50Hz. So the PLL is locked .
Was kann die Ursache sein?
