Hi Olaf, Am a new member so bear with me if I am not doing this correctly. I have just seen your post on the Codan 8525S. I also have one which came with the yacht. I sent it away for service and it works which is a good start. It only has the manual tuner. But I also do not have the frequency list and am hoping that you could email me your list also. Mine seems to only have 66 channels (manual says 99) but am sure with a list to start with will help tremendously. I can then research connection times to cross-ref. Can this model still be upgraded with a new eprom with latest frequencies do you know? And would you know who? Regards Ian
