Hi Guys,
During these long summer days from around second week in May until around September I recieve the beacon at S1-S5 in the early morning from around 05:00 until about 10:00 and then it comes back around 19:00 till about 21:00. The varibles from S1 to S5 is really strong now i understand 50mhz propagation but wonder why i dont hear it so often during the winter. Its some 410km from my location so its really great hearing it and i have it monitoring most mornings. I ve noticed that at S5 then there generally is some "E" around and i will swing the beam more east and work a few countries. At S1 there is no propagation! Now the question, is it that i can hear the beacon during the summer months because of the warming up of the ground and i would say the sea near GB3MCB and thats why i hear it? Only on some occasions can i hear it during winter.

Well I suppose at least 241 people are reading your post Andy so your thoughts are at least being heard.
Personally I don't know the answer to your question; I guess your mention of ground warming is a suggestion that this possibly affects tropospheric propagation?  An interesting thought but I have absolutely no idea whether that is indeed the case.  Perhaps one of our members with meterological experience could shed some light?

Thanks trev, it really interests me in how the beacons fade in and out with the seasons.
