For the OFDM modem in 1.4.1 700D,
What is the sample clock offset corrector's maximum offset for pull-in,
and hold in ?
investigating some trouble here.
I'm guess the pull clock for the TX samples are generated by the sound
device, and errors there will be the sound device and any error in the
SRC . The IC7300 in freeDV it comes up as a 44100 device, so I am going
to have to verify SRConverter errors (windows) (linux) and, also
exactly what the USB crystal clock measures in the IC7300.
The IC7300 and IC9700 has a resonator/crystal which it generates the
USB audio clocks with, as in the 7300 the USB audio is mere;y a DAC/ADC
from the analog circuitry,
