There seems to be a lot of lift conditions in the last few weeks. Here on the east coast of Ireland, I have an FM dipole in the attic and was picking up BBC radio from Wales perfectly, as well as an ILR from the west of Ireland (Midwest Radio). Today I got Radio Vltava from Czech Republic fading in and out on 96.1 for a few minutes. At one stage it got strong enough to get RDS lock, hence how I identified the station.

Interesting times.

OpenBox X5 on a 1 meter motorized dish.
And now a 10 foot "C" band dish.

Deep in the Boonies in the central Sierra Nevada mountains of California.
Lots of 2 meter propagation (would cover the FM band as well) going on on that side of the big pond, I use this site for tracking when can I talk further then down the county.

Are you sure it's Tropo from the Czech Republic? I think it might be Sporadic E if it fades in a few minutes.

You're most likely right and I'm using the wrong terminology!

A little less analogue, and a lot more crap.

It’s Sporadic E skip rather than tropospheric ducting for the long distance stations.

The conditions over this weekend have been exceptional for it. I heard FM stations from Algeria, Southern France and Italy on Friday, as well as a single one from Iceland at one point, and then Spanish and Portuguese ones yesterday and today. Some people have been getting central and Eastern European ones too.

The usual limit for ducting is around 800-1000 miles. Many of the locations you have mentioned are at the limit, but not impossible, your set up may also have some advantages, a good outdoor antenna and a selective receiver.

That's true. To clarify, I meant in this specific instance, the reception of these stations over the past few days has been due to E skip rather than tropospheric ducting. There's been E skip across large parts of Europe, including the UK and Ireland.

Feel free to change the title, I now know I got it wrong. :) Tropo would be for UHF I assume?

Not at all, tropospheric impacts on lower frequencies as well.

Have you checked there hasn't been a dual set of conditions running ?

Meteor scatter might also be apparent.
