    I've found this both in the car and using standalone receivers and its been like that both from the studio based broadcasts and this weekend from #RossRevenge - maybe they've changed the #soundprocessing, a piece of equipment has failed somewhere or the RF power has been turned down to save electricity?

      its possible they deliberately increased treble at expense of bass for more range (or because of complaints audio sounded "muddy"), as on my 1990s Coomber schools receiver (100% analogue) I had to turn down treble or else I get hiss/noise from QRM (likely from VDSL/SOGEA line in here)

      Some European Communications Ministries (including Ofcom UK and likely RDI NL as well) are allowing full 9 kHz audio bandwidth on AM (increased from 6,3 kHz) once more as compared to 1980s there are way fewer stations on MF (a lot of Northern European commercial stations and even PSBs have stopped using this band - its still used in Southern Europe which is why Caroline can't go to 25 kW or they would interfere with RTVE Spain (MF radio was valuable there during the major power cut)

        #RadioCaroline has lost programme audio altogether and is transmitting dead air now (more likely due to the ropey LTE connectivity across East Anglia - nowadays they use a 15cm LTE antenna hidden in the mast of the Ross Revenge (they aren't allowed to use the TX thats on there and I don't think it works anyway as PTT RCD NL ripped out a lot of the vital parts during the 1990 raid - I think RDI (Rijksinspectie Digitale Infrastructuur) literally only returned them last year...

          they are back on air now, that was a good few minutes with both AM and the stream silent (although curiously there was hiss on the stream, surely they aren't using an *analogue* link for this in this century?)

              @gemlog I grew up with this station from mid 1980s - in those days microcomputers had near 0 EMC shielding (the EU only insisted on it it around late 80s/early 90s), so VHF/FM was wiped out whenever I wanted to use my computer but MF was listenable (with maybe a bit of extra hiss)

                Caroline Flashback has been hit & miss all afternoon as well.
                I'd guess it's something at HQ
