What's your received signal power? For instance, this guy (no idea if he's right) shows simulated GMSK BER curves with a 5e-3 BER anywhere from 8db - 14db depending on the bandwidth-time product: http://iaci.unq.edu.ar/materias/telecomunicaciones/archivos/infoadicional/esquemas_de_modulacion_digital.pdf Just a thought. Since it's corrupt packets you're talking about and not bits, things should be a bit different, but with any decent FEC the packet error rate should be much lower than that. <http://iaci.unq.edu.ar/materias/telecomunicaciones/archivos/infoadicional/esquemas_de_modulacion_digital.pdf> -William
