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 like 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 "phantom station" but it must be close to the carrier of Lakihegy. Using AM detection 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 bandpass filter is very effective and there are only weak traces of signals above 150kHz. BR Paul-Henrik, OH1LSQ
