This frequency is where you usually find the 'L' beacon, today however it is sending F's- only every 6th 'F' is a 'C'! This beacon has a long history of being quirky- up until about 10 years ago it was chirpy and sometimes had the odd dit missing- as if a mechanical keyer was used that had bad contacts. Then it seemed to get an overhaul and behaved itself for a bit. Actual carrier frequency is about 8498.55
