French, Portuguese and Italian language signals all mixing together this afternoon/evening.  Tuned in via the G8JNJ SDR (located in the South West UK).  Some stations are running hi-fi SSB or eSSB transceivers - likely higher-end amateur radio equipment.  SSB bandwidth usually is in the 2.8 kHz to 3.1 kHz range, the higher end audio signals were easily 4.5 kHz to 5 kHz wide so 5K00J3E instead of 2K80J3E emission.
