I have been watching at the bottom of the band for the return of the Greek Naval station, which has been off-air for a few days now. I wonder if you have a neighbour who has just got a new wide screen TV. These produce and radiate power supply switching signals at around 35kHz and its harmonics. The main signal is modulated by about 4 or 8 sidebands at 100Hz and often also 50Hz (often weaker than the 100Hz lines) spacing. I believe that the radiation is via the coax braid on the aerial, it certainly can travel quite a fair distance....100s of yards. Older conventional TV sets dont seem to give this kind of trouble. So much for EU EMC legislation. Cheers de Alan G3NYK Alan.Melia@btinternet.com
