DX: 22.03.2013- TEP (TV)

Startbeitrag von Hugh am 23.03.2013 09:48

Hi,

There was some TEP from South America received in Portugal on Ch A2 at 19.55 utc.



The video is of a 525 line signal,probably Brazil.

By 20.15 a 625 lines signal starting to mix in with it,which will be from Argentina/Urugyay/Paraguay for sure,slowly fading up and down with a strange offset giving the video howl effect.(just above 55.250)

Video is below ,something is recognisable as a 625 image,especially near the beginning.When 525 comes up the 60 Hz buzz is there and the syncs move digonally from bottom top right to bottom left(local sync is on 625).When 625 is there the image is locked and the 50 Hz buzz is on the audio.

The MUF was not high enough for TV sound.



Good DX !

Hugh

H Ruud,

Thanks...I'll have to find their live stream and compare it if the more southerly Brazilians come in again....525 mixing with 625 line signals is a good check for the general area.

Brazil is due to close analogue TV in mid 2016

Argentina,Uruguay and Paraguay use system N which is similar to system M but 625 lines
because the have 50 Hz mains supplies and not 60.
