FM Dxing

During the 3rd week of June 2010, I had an opportunity of experiencing sporadic e condition in FM band. Earlier, Noticing various distant FM logs, I tried several times from my hometown Kolkata with available receivers. But strong local FM channels & their image frequencies all over the FM band, prevented me to log any distant FM channels. Then dismantling newly home brewed Quad Loop antenna, shifted to another 100 km north of Kolkata, a place called Taherpur (Coordinates 23.18°N 88.58°E) under Nadia district of West Bengal state. Erected a 20 mtr. longwire targeting southeast & northwest. The very first day Quad miserably failed & later on detected that there was no continuity. Then the magic started with the longwire which later on found performing excellent. I used a tiny Tecsun PL 757A portable receiver. Many of the distant FM stations coming like our local FM channels, specially from Pakistan. As if, I am sitting in a city of Pakistan. Most of the pvt. FM channels of Bangladesh like Radio Foorti, Dhaka, Radio Amar, Radio Today Dhaka, were coming very clear. Most surprisingly received BBC Bengali programme via FM at Comilla, Bangladesh. Many of the stations carrying programme in CIS language, could not be identified. Indeed, it is not so easy to perfectly identify a distant FM channel just crosschecking their frequency in the available gadgets. Because various programme run in the same channel in various city of the same country. Although Indian pvt FM channels could not disturb the band much but some channels from central to northwestern India were available. Many of the Thai & Vietnamese channels remained unidentified.

But coming back in Kolkata tried several times but nothing fruitful so far. Quad Loop antenna was also erected perfectly. Definitely this was the first experience of sporadic e. Next one will must be a planned FM dxpedition.
