My Best Tropo FM DX
European tropo FM DX record 2007-2016
European tropo FM DX record 2007-2016
1706 km: Keelylang Hill, Orkney (Scotland, UK)
93.7 MHz - BBC Radio Scotland FM
Received during BIG TROPO on 17-18 December 2007
Since 2017 not my furthest tropo catch, but it still is my best because of the signal strength and endurance - it was there for over 2 days in a row!

My most distant FM DX
1743 km: Kolari, Yllas Mountain (Northern Finland)
100.7 MHz - YLE Puhe
Received during MEGA TROPO on 27th September 2017
My ODX appears at the end of this video (also including 1558 km Kalix, Northern Sweden):
(Yllas was mixing with a closer transmitter of the same station, but the "echo" of 2 txs is obvious)
27.09.17 tropo report (in Polish).
The same transmitter picked a little further, by my colleague Łukasz in Tomaszów Mazowiecki was a new Polish (and for a year a European too!) tropo FM DX record (with 1798km!)

The most extreme FM DX tropo propagation
906 km: Ućka, the coast of Adriatic Sea in Central Poland!
99.3 MHz - Hrvatski Radio 1
28th August 2016
Not the most distant tropo, but what a style! The path of the ducting crossed double mountain ranges! And the signal was quite strong too:

The most extreme tropo TV DX
1466 km: London-Croydon & 1427km Bluebell Hill (UK!)
(UHF band, analogue)
The absolutely amazing tropo of december 2004 (report in Polish) brought a flood of UHF TV signals from Western Europe! It was of course back in the days of the analogue TV. I received dozens of German terrestrial channels, and in the afternoon Dutch started showing up. Here are their recordings:Briefly at around 5pm I picked two analogue UHF channels from the UK! Initially I had no clue, because there were no logos on the screen. But at some point I noticed "five" and "BBC" on some captions during the programming. I couldn't receive the audio, because UK operated analogue PAL system with a different audio standard (not compliant with my tv set then) - instead both channels were showing with German audio. My biggest regret: back then, I had no camera to take a pic!
I eventually identified them as: Channel5 from London/Croydon on channel 37 UHF (1000kW); and BBC2 from Bluebell Hill on channel 46 UHF (only 30kW!) - both in color! They faded to be replaced by GER & NL tv stations again. The ducting continued into late evening, gradually losing strength.
Also:
Easternmost tropo reception: MOSCOW @1170km!
Such far distances in eastern directions have never been available via tropo from Central Europe for at least 15 years - as long as I have been FM DXing. Moscow via troposphere has never been reported tropospherically from Poland!
Tropo ducting on October 10th, 2018 - I managed to pick 4 stations from Moscow then:
90.3 Avtoradio, 93.2 Studio21, 102.5 Comedy Radio, 107.8 Militseyskaya Volna

More tropo FM DX records from Poland:
Do also check the fantastic achievements of my Polish DX colleagues: Konrad in Plock and Lukasz in Tomaszów Mazowiecki.
Konrad's logs are approaching to a total of 4000 received tropo stations, including UK, Italy and Dutch pirates with RDS - Yes, we are talking tropo!
Lukasz has fixed Polish tropo FM DX record with almost 1800 kms! (to Kolari, Finland). His log exceeds 3400 entries!
