  • You should tell people up front that these zero crossover relays will not work well for highly inductive loads like some power supplies and motors.

  • Matt, also KC0MKS Jeff de w0it Louis. I think that this transmitter as configured has a big spike on the first harmonic, but it could be that my receiver picks up on the harmonics. I may get it into work where a friend has access to a spectrum analyzer that gets up that high in mhz. The receiver is very wide and noisy from my limited tests. I spent the day looking at low pass filters. It would be sweet to have something really low power that would do the link thing. The thing works pretty well for sending morse short distances. I am looking for a locally viable morse setup that is this sort of cheap. ( I used a version of this from Seeedstudio .
