Está no site do Danish Club, o conteúdo de palestra proferida pelo Sr. Anker Petersen no DX-Parliament em Laholm na Suécia no dia 16 de fevereiro de 2007, com o título Tropical Bands in review. Lembrando alguns pontos curiosos desta palestra, segundo os seus registros (do Sr. Anker), 800 emissoras, ou 73% das emissoras ativas OT em 1973 desapareceram em 2007 (de 1106 para 307). O país com o maior número de emissoras é o Brasil com 45, mas as redes de rádio com os seus sistemas de satélite estabelecem uma tendencia de declínio, que de 1973 para 2007 registrou-se a perda de mais da metade de suas frequencias, no caso brasileiro. Alem do Brasil, é traçado um perfil de diversos paíse e regiões como o Pacífico, Guiné Equatorial, Zimbabwe, America do Sul, Central, sendo muitos destes locais visitados pelo Sr. Anker.Casos curiosos como p. ex. o da Indonesia que era um paraíso dexístico nos anos 1970, com suas 171 emissoras em 1973 ; em 2007 apenas15! Ele relata também uma emissora que ouvi um bocado nos anos 1990 que é a Radio Lesotho em 4800kHz, que saiu do ar em 2002; o transmissor espera até hoje peças de reposição. Escuta desta emissora em 12/08/95, as 05:00utc pode ser ouvida aqui:

http://geocities.yahoo.com.br/eefibra/r.lesotho.0500utv.0895.mp3 Outro caso de estação com equipamento em mau estado foi atestada pelo dexista escocês George Brown, quando de sua visita à R. Vanuatu em novembro de 2001. Eles usam um transmissor de 2 canais de 10 kW sintonizados em 4960 e 7260kHz, trocando as frequencias de acordo com o inicio e o fim do dia. Durante a visita, um dos canais do transmissor desenvolveu uma falha, implicando no uso do mesmo canal o tempo todo. O outro transmissor de reserva em 3945kHz estava desativado por falta de peças; pelo que se ouviu no ano passado, este transmissor em 3945kHz foi consertado mas  a frequencia de 4960kHz continua sem ser ouvida; 7260kHz. foi ouvida em 12/08/06.

O decrécimo de emissoras em OT tem aumentado significativamente: de 1973 a 1997 saíram do ar uma média de 20 emissoras por ano, mas de 1997 a 2001 a média saltou de 74 por ano! Atualmente tem se mantido na casa de 14/média/ano. Mantendo- se esta média o número ZERO se atingirá em 2029, quando então se extinguirão as OT. E o que farão os dexistas após 2029? Segundo Anker Petersen as ondas médias e as emissoras internacionais ainda resistirão.

 4451.202Khz  Bolivia R. La Cruz del Sur, identified by Lucio Otavio 
Bobrowiec, 2350 with om, no music, .... off *2354 on 8 February [Wilkner-FL]

 Audio file containing first male next female announcer mentioning “R. La Cruz del Sur”

very short, 37 kbt, 7 seconds here:

http://geocities.yahoo.com.br/eefibra/r.cruzdelsur4450khz060208.mp3

 Sometimes they mentions “Radiocomunicación Roco” what could generates doubt, and should sounds like “Radio...Co”, “Radio Eco”. Radiocomunicación Roco maybe is the name of the owner of R. La Cruz del Sur.

Dear Lucio,

A very interesting observation, you made! But the audio is very noisy and difficult to understand, but I think I heard the ID.

Best 73,

I kept listening and recording 4451KHz as R. Cruz del Sur, BOL, then checking later this recordings, heard something readable as “R. Santana” or maybe “Guantana”. Some two days before it, the Brazilian dxer Rogildo Aragao, who reside in Bolivia, informed me that on 4451KHz is R. Santa Ana, Santana de Yacuma, Beni  BOL. But the reason of so many mentions heard on 4451KHz of R. Cruz del Sur is now for me, unknowable. Below, link to audio file that contains male announcing “R. Santana” or maybe “R.Guantana”.        very short audio file 98kbt, 8 seconds: http://geocities.yahoo.com.br/eefibra/r.lacruzdelsur.r.guantana4450khz0208.mp3

Now that you mention it, I don`t recall seeing this reported for quite 

some time, unlike its other frequency 4450. Has 4557 been off? (gh)

But now we must be more careful than ever on 4800, as R. Buenas 

Nuevas, Guatemala, has also been active there in last few weeks. Both 

seem to be sporadic, and at least when I tune around 0630 and 1330 

hear neither. RBN may be in Spanish or vernacular, while XERTA would 

be only in Spanish (Glenn Hauser, OK, DX LISTENING DIGEST) E.g. así:
