I have been listening to SSB with an RTL dongle and SDR Console, and had excellent results. I swapped to my brand new Pluto SDR and see a lot of regularly spaced lines of interference on the waterfall. This is on the same USB port of the same laptop, and the same dish and Bulls Eye LNB. Disconnecting the LNB causes the interference to disappear. Running the LNB bias T from a battery does not get rid of the interference.
Has anyone any ideas as to what the cause may be please? Thanks
