I too received this unmodulated carrier most of yesterday too, sometimes S9 in N England. Considering the frequency, and the size of it's dead skip zone around Ireland, it may have been Harmony's TX. Today nothing, so maybe the TX is being serviced or they have a problem. It seems a bit of a coincidence for it not to have been Harmony, due to freq having been used by them these last few days and harmony not being on any other wavelength at the moment.
