Re: Patch to Include LNA enhancement and IF gain and filter settings for FCD

I agree about the IF RC Filter and IF Filter, I perhaps was a bit
overzealous when adding them. However, I do find being able to adjust
the
IF Gain’s to be useful when in noisy environments as a way of lowering
the
gain (or increasing if necessary) even more beyond the the LNA and Mixer
stages.

Okay, I’m going to agree to include the extra API; however, before the
patch can be applied corrections are necessary. In most functions you
will
have to either reverse the inequality sign or the order of the
conditions
for the parameters to have any effect. Also note that you have a gap for
the IF gains between 0.0 and the next value. Furthermore, I would also
ask
to always make the split halfway between the two values rather than at
one
of the values (e.g. you want 8.9 to be rounded up to 9.0 instead of down
to
6).

According to the patch, a file called fcd_rx.grc has been added to
gr-fcd/examples/grc/CMakeLists.txt but no such file is included in the
patch.
