This is part of the TX spec on N9VV's website:
TX bandwidth: 100-3900 Hz in 10-Hz steps.
TX frequency response: 100-4000 Hz max -6 dB points.
TX equalizer: Up to 6 dB/octave bass/treble boost/cut.
TX speech monitor: Audio taken after filtering, processing.
The hi-fi group are already waxing enthusiastic over the Orion because it
will have the wider transmit bandwidth without having to be modified, etc.
Doug Smith's "other" project - the Kachina 505 DSP - covers either 3.1 or
4.0 KHz, but the low-frequency response of the filters and audio section is
so poor (DSP IF filters and audio system response starts rolling off at 500
Hz) that they are seldom used for wide-frequency-response operation.
Have you seen any IP numbers for the transmitter?
