Thanks again for the help. My problem is that there are no frequency or wavelength markings for LW on the Roberts R200. I need somebody with an alligned R200 to tune to these LW stations and then tell me what the reading is on the MW scale.

It would be a lot easier if I had a signal generator. The allignment procedure says you should tune to 425m on the MW scale and then inject 185 kHz. From this I know that 425m on MW scale corresponds to 1622m on the LW scale. But that doesn't help me.

Hope someone can help me some more with this.
