Okay, that's a vote for running, um, normal audio throughout the controller. To do that, we would accept normal audio from receivers as-is, or de-emphasize discriminator audio. The controller's internal tone generation and digital audio playback, the DTMF decoders, and the autopatch all stay normal. We wouldn't need squelch circuits and we wouldn't need pre-emphasis and clippers in the transmitter audio. It would definitely be less expensive. And normal. :-) 73, Bob ________________________________________________________________________ AOL now offers free email to everyone. Find out more about what's free from AOL at AOL.com.
