FM via TEP in Chile

Post by pe1etr » 11 Mar 2018 08:19

Hello all,
TEP in South America is still happening.
This is from Mauricio Toro in Villa Alemana, Chile
Reception of 88.5 Radio Tiempo Cartegena, Colombia 10.03.2018
Sony XDR F1HD with GTK software, 7 ele log yagi

Fascinating. The reception is stable and it sounds like weak tropo.

In theory would your location be good for TEP?
Good DX.

I saw the log last night on FM List. Last week he also received TEP signals.

The problem is that FM via TEP is usually a strict N-S path, the southern end of that path for me is the empty South Atlantic. A further complication is that the Geomagnetuc Equator is skewed as it passes from Africa to Brazil. My FM band is also full.

Distances were further (~ 7000 km) between Europe and Botswana when I received FM TEP. It always sounded to me like weakish tropo which was through the back of a yagi with multipath distortion. (Band I STLs were better audio quality often with RDS and greater distances).

I discovered Mauricio's YT channel when he subscribed to mine recently.

Old age, poor memory
Just remembered many years ago a radio ham in Brazil, George I think, posted some audio clips of West African FM he had received. He was puzzled by this, and his fellow hams told him it was tropo, however, as soon as I heard the clips, I knew it was TEP.

Close to the Geomagnetic Equator reception is on a E-W path rather than a N-S path, but it sounds the same.
