It is a rasping sound rather like a spark transmitter and sending something like NX in very bad morse at around 5WPM. The QRM is broadband centred around 14MHz and is on 24hrs a day. I have reported the matter to BT who hav been out to investigate but are unable to find the source or even say what it is. I have also sent a tape to David Lauder, the RSGB EMC guru but even he does not know what it is. With my bicycle mobile I have travelled around the vicinity in a radius of around 3km of my QTH and find the QRM widespread with hot spots often by telephone line distribution poles. Most telephone poles do not carry the interference. The interference does not affect 136kHz - hence Off Topic. Regards, Peter, G3LDO e-mail
