Hi gang, First question: Does anyone know anything about TV transmitters around the South Herts area? I had to retune my video to the alternate BBC2 and C4 channels... and Chan5 decided to ruin my SAM picture!!! :(
So, I opened up the power pack and twiddled the modulation screws until I got a non-interfered picture. Which brings me onto the second question: I've discovered that one black twiddler controls the TV picture channel and the other is the sound but - what do the two brass twiddlers do? Twiddling them didn't seem to do a thing. Justin. (Please excuse the "technical" terms for potentiometers - it's still early in the morning.)
