Eng. Dept., U of Maryland, College Park, MD 20742 Lines: 10 I'm not so sure about not sending digital on 27 or 49MHz is necessarily illegal. Random radio controlled cars use these freq- uencies all the time and the signals are more or less "digital". I think that the FCC is more concerned with bandwidth. 9600 baud is out of the question, but I'm sure you could get away with 300, maybe even 1200. If you were to apply a suitable low pass characteristic to your signal, who would know you weren't playing with an RC? It ain't a crime 'til you get caught.
