Daniel, due to a combinatorial explosion caused by the number of changes
required for the digital frequency tables and not knowing for sure which
patches will be applied and in which order, I'm going to hold off on the
fine-tuning patches for digital channels until some of the others are
applied. Since you previously indicated a desire to fix the major
issues before 0.20 and hold off on the fine-tuning until after (to allow
for better testing), this should fit your plans.
The issue is that to fine-tune the HRC frequency table, I'll have to use
a _frequencyStep of 6000300Hz, but standard and IRC still need to use
6000000Hz. Therefore, I'll need to modify the FREQ define to allow
specifying the _frequencyStep, which will affect every line of the
definitions. Also, I'll need to break out the radiocommunication and
radionavigation bands for standard and the radionavigation bands for IRC
into separate entries. Once we've got the important fixes in SVN, I'll
make patches to do the fine tuning so I don't have to make before/after
patches for every combination.
Thanks,
Mike
