mernisse-guest pushed a commit to branch master
in repository dump1090.
commit f64a65b5a20075194206fca903e8e04e9913e090
Author: Malcolm Robb <Support at ATTAvionics.com>
Date: Fri May 24 21:51:44 2013 +0100
Tidy up of UKUEHN's improvements
Resolves some merge conflicts that I couldn't find a way to fix during
the previous merge.
Remove a few Tabs that escaped in the edit/merge
Rename the fix_errors flag variable to nFix_crc since it now represents
the number of crc errors to attempt to fix.
Remove the aggressive variable since it's now part of nFix_crc
Only print phase correction statistics when phase correction is enabled.
Add an additional Modes.stat_ph_bit_fix[] to count the bits fixed during
phase correction
