On the 17th of may I once again had chaine 3 87.6 in big letters this must be the limit for these kind of signals, something does seem to come through again, it comes all the way from north africa, is a long way for an fm signal to travel.
I also heard a number stations on the newcastle receiver on the 20th, though they sounded german, may of been danish, frying away, they were on 87.7 and 87.9, 87.9,93.2,
95.1, 101.4, 102.1,103.3, 95.1,102.1 some were stronger
the rds came up 102.1 radio 4 rangstrup dnk 696kms. these traveling under tropo
Checked the cambridge receiver no stations coming through, there weren't any stations I could hear at home either at the time, makes it quite interesting maybe you can travel afew 10’s of miles and not hear a lift, its worth checking.

That was far for sure about 1,300 miles or so. I must have missed your post sorry I ignored it cause I like a bit of
FM DX signal on my TECSUNs radio. Doubt I could hear that with indoor antenna though.

Well done for hearing it, that must be close to the limits as you say. You heard it from another continent ! Algeria blooming hell.

Here is someone else hearing it for others to hear as well.

I've heard Chaine 3 on 87.6 from Algeria on FM a couple of times. It pops up when there's a Sporadic-E opening in that direction. Must be on quite a high site. It's only 1689 km (1050 miles) from me.

Best DX so far as distance goes on FM is BNR Radio in Bulgaria, which I heard at a distance of 2102 km (1306 miles). Also, as these things go, on 87.6.

Favourite DX overall is Vesti FM in Kaliningrad on 95.1. Only 1356 km (843 miles) but just a 1 kW TX and in that tiny Russian enclave hemmed in by Lithuania and Poland, so quite a rarity.

Other countries do have some big mountains, 87.6 is also very clear nothing but those in car dab adaptors in the uk. The e layer is 100kms up, higher than the d layer that reflects mw signals at night, you can get more than one bunny hoop, wiki has some distance records, how spooked they must of been to recieve italian tv back in 1939. https://en.wikipedia.org/wiki/Sporadic_E_propagation
I did wonder if there was a minimum power requirement, think saw in the past sounded like an rsl station received in some other country, assuming the more powerful the stronger the signal would be when it hoops over, I don’t tottally understand it. Afew weeks ago i’m sure I heard the call the prayer over muilple frequencies, sounded like some were far away, imagine some were hot a desert. Transatlantic reception is the dream, only possible down the west coast of ireland, canada is closer than america, would still count, newfoundland, thanks for the replies.

Its possible to hear long distance low power stations running just a few watts during a Sporadic E opening. What you hear depends on distance and position of the clouds and your angle to the horizon. If you live near the sea or mostly flat land you'll most likely hear more.

the coast is good usually far away from other radio stations the band can be alot cleaner allowing more stations to come through. I do remember it knocking out all fm stations, years ago have a vague memory of tv picture going a funny color, something there in the backround.

I suppose a signal of a few watts could be heard in another country by spe, if someone were to do it themselfs, the frequency would have to clear the other end (likely be on an 87 frequency) would have to be on air at the exact time of the lift, running id’s, theres too many variables there, the rarity of such transmissions.

Anyone tried Aircraft scatter on DXsing at FM?

Local hams do it much on 2m and 70cm to reach other end of country, they just watch ADS-B relay on 1090Mhz using cheap RTL-SDR, splot planes on map and turn their yagis towards them.

Nice 700-1200km QSOs easily.

Flightradar shows lots of planes between UK and EU, so build nice yagi for FM, open Flightradar or watch 1090Mhz and start hunting DX.

Hams run 5-9 elements on 2m for this, 5element on FM might be enough, much higher transmitter powers.

Quick calculation using ham tools because they are everywhere and free.

10dBi yagia and +80W FM rig at 145Mhz is enough to bounce of an plane, so that 10kW ERP FM station will bounce of from plane.

My best ever VHF DX was on 145.525 MHz (S21) when I was mending a friend's Yaesu FT 203R. The receiver had "gone deaf" which was (usually) because the front-end FET had died. The fix was to replace the FET and add a couple of parallel diodes from gate to ground to shunt any static, and prevent further failures.

I'd repaired the radio, and it was on my workbench, listening to the local traffic on S21. Suddenly it went quiet. I thought "Damn - the FET's gone again", then I heard a weak signal calling CQ, with a CN/G8 callsign. I gave him a call back - 2.5 Watts into a helical rubber duck aerial.

He replied, and we chatted for about four minutes, until he disappeared into the noise, to be replaced with the local chatter again. He was using an Icom IC2E.

It turned out that he was a power engineer, working on a site in Morocco, and he was calling his assistant - another G8 - at the bottom of the hill, to put the kettle on! I worked out the path distance from my old house in Terheijden in Noord Brabant, about 6.5 km north of Breda, to his site in Morocco, he was at "al Massira" hydro-electric station, ~2500km away!

It was - undoubtedly - a tropo-ducting event, and was quite anazing.

A friend of mine has successfully "made the trip" on 2m from the West of Ireland to eastern Canada using ducting. That's got to be some kind of record!
