FEVER fixes a bug in the receiver frontend FIR code where the history
buffer is shifted to add a new sample. Because FEVER *could* change
audio levels for folks that may have precisely adjusted them (in ACID),
FEVER is only turned on IF you do a "radio tune rxnoise"
re-calibration. FEVER was instated in ACID in January 2015, and
therefore ported to DIAL by default. As far as I'm aware, every install
of DIAL incorporates FEVER, and as long as you do a radio calibration,
it eliminates this issue.
FEVER stands for Front End VERsion, and is the work of Jim Dixon -
WB6NIL, where he incorporates the bug fix provided by Jeff DePolo -
WN3A. Jim made it so that the "tune" file for the chan_usbradio channel
saves a "front-end version" and now, if you do the "front end tuning"
using the "radio tune rxnoise" command, it will set the mode for the new
fixed version, and save it that way. In other words, any new
installations (since January 2015) will auto-magically be running the
new, fixed version, and any old installations will not be effected
unless they re-do the tuning, in which case it is likely to sound better.
Hope this helps...
