Marked as duplicate / proposed merge
I have marked this as a duplicate/proposed merge of Tropospheric scatter article. It is my belief that these two articles describe different applications of the same propagation mode and are small enough to practically merge as one article. Discuss here.Defrector (talk) 11:06, 21 July 2013 (UTC)

This article also doesn't say how the EM waves actually reflect off the troposphere. What is the EM energy inteacting with to cause the reflection. A little bit of physics goes a long way. -anon —Preceding unsigned comment added by 220.127.116.11 (talk) 20:02, 16 June 2010 (UTC)
- there was no link on the section header to the article about DXing. if there was one, someone deleted it. i put it back in. i also added a one sentence explanation of DXing at the top of the section.Colbey84 (talk) 02:46, 13 November 2016 (UTC)
Notable tropospheric DX receptions
- Going twice. Will Beback talk 07:08, 27 December 2011 (UTC)
- During October 1975, several United Kingdom DXers received band III and UHF television signals from Finland, Poland, Czechoslovakia, and the USSR at a distance of over 1,000 miles (1,609 km).
- On December 3, 1975, Robert Copeman, Sydney, Australia, received Auckland, New Zealand, TV-2 NZch4 band III TV at a great-circle distance of 1,340 miles (2,157 km).
- From 1989 to 1994, FM stations and TV VHF/UHF stations from Florida, and even from Alabama, USA were received in Havana and other parts of Cuba. VHF low band channels from Puerto Rico, Dominican Republic and Mexico were also received during summer afternoons.
- On June 26, 2009, a weak signal from WOI (Iowa Public Radio) FM 90.1 in Des Moines was received on a portable radio in the Merrymount section of Melvin Village, New Hampshire, at a distance of approximately 1,140 miles, and on June 30, 2009, a strong signal from WMBI (Moody Bible Institute) FM 90.1 in Chicago was received clearly on a car radio in East Moultonborough and Melvin Village, New Hampshire, at a distance of approximately 839 miles.
- On August 28, 2009 Romanian dxer "Zvartoshu" received FM ERTU Moskee, 93,1MHz via tropo multihop in Bucharest in Piata Unirii central zone, at a distance 1,688 kilometres (1,049 mi).
- On the afternoon of June 25, 2011, a DX'er and Radio Engineer, Bob Gilmore, received WMIX 94.1 from Illinois in Southern Connecticut.
- During the late night hours of July 19, 2011, Amateur DXer Chris Barrows received DTV station WNTZ-TV from Natchez, Mississippi in Decatur, Texas, a distance of up to 385 miles.
Additional unsourced notable reception
Any objections to removing this seemingly impossible reception? Unless I see a source, I have a very hard time believing such a thing was possible
- On October 3 2012, an American Ham Radio operator N3MPE was heard over a UHF CB emergency repeater located 40km north of Brisbane, Australia --ḾỊḼʘɴίcả • Talk • I DX for fun! 03:40, 23 October 2012 (UTC)
This part of the article "while with tropospheric-bending, stable signals with good signal strength from 500+ miles (800+ km) away are not common when the HA JA JA index of the atmosphere is fairly high." doesn't seem right... I suspect its supposed to read "are not uncommon when" ... ?? — Preceding unsigned comment added by 18.104.22.168 (talk) 07:32, 5 September 2013 (UTC)
- exactly why i came here. it seems that it should be "not UNcommon". i'm very tempted to change it, especially since the previous question about it has gone unanswered for over 3 years. however, the "...WHILE with tropospheric-bending" makes me hesitate. that phrasing would normally indicate a DIFFERENCE from the first part of the sentence, (which discussed tropo-ducting). with no further discussion about tropo-bending, i find it difficult to understand the difference.
- i get that tropo-bending is a form of tropo-propagation (where "running into" a "wall" of warmer air causes the signal to "bend" around the globe rather than continuing in a straight line). is it that tropo-ducting is a form of tropo-propagation, and tropo-bending is a form of tropo-ducting??
- if that's correct, the sentence is still confusing. with the "WHILE," maybe it should be referring to different frequencies?? meaning, the 1st part of the sentence is about UHF signals being picked up 800 miles away, and the 2nd half is about VHF signals being picked up 500 miles away??
- and, if THAT'S correct, it should STILL be "UNcommon."Colbey84 (talk) 02:15, 13 November 2016 (UTC)
