As far as I know, at 8000 Kbaud, you're going to have a "audio" signal of at least 8 Khz (if not more). Aren't the transceivers going to filter this on their bypass-deempĥasis port? I don't know if any radio will accept such a signal, even at their 9k6 port. (Does anybody have any experience what is the maximum frequency that is accepted on the "9k6" port of a typical radio?) 73 Kristoff - ON1ARF ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity, and more.
