   Hi Tony,   
      
    JS> Me either. It only seems to be an issue on 10m. As transmitting on any   
    JS> other HF bands doesn't appear to bother that TV at all.   
      
   TL> Obviously something really picks up 10m.  Years ago, home alarms had   
   TL> a similar problem, most commonly triggered by 40m, but no other   
   TL> band.   
      
   We had a similar problem. The TV-sets manufactured in the 1950-1960's   
   had an IF-frequency of 21 MHz. Obviously we had to avoid working on the   
   15m, and to some extent 40m bands, since 7 MHz * 3 = 21 MHz.   
      
   Luckily, in those early TV days, they were not transmitting programs   
   24h/day, so we could operate ham radio outside TV-hours.
