It= has been a regular occurance here lately after dark. After some identification= work I have a match on the running programmes on 171 and 225kHz, 225kHz being= the stronger. I blamed my RX chain at first and started to eliminate IMD possibilities= but even now using a passive antenna and a very sharp bandpass filter (much li= ke an IF-filter for a valve BC-set) I still have the BC splatter. So far I have not been able to determine the carrier frequency of this "ph= antom station" but it must be close to the carrier of Lakihegy. Using AM detecti= on with a narrow filter it seems centered around 135.4kHz. Sounds like two BC-stations on top of eachother and the USB reaches up in the amateur band making "ghost whispers". Luxembourg effect, transmitter IMD or just me missing the point? The bandp= ass filter is very effective and there are only weak traces of signals above 150kHz. BR Paul-Henrik, OH1LSQ
