  • Yes, in fact you should use µ instead of µ0. µ0 is the vacuum permeability and µ=µ0*µr where µr is the relative permeability of the material. µr=1 in the case of air coils that’s probably why you made this mistake.

  • Hi, what kind of antenna may I use with this receiver and the appropriate transmitter? I haven’t seen 434MHz antennas here… Thanks

No public wish lists :(
