I am using the new GR 3.5.3 (tar) on OpenSuse with FCD. My FCD needs
some special values at IQphase an IQgain balance as well as DC I and DC
Q offset to suppress unwanted sidebands.
When I fill the known values into the properties as a number, they do
nothing – totally misalainged, same as no given parameters in the
properties dialog
When i fill in a variable slider with that wanted value as default value
– it is the same; but when I move the slider a step and back to
default, then everything works as expected – the values are now correct
and the sideband suppression is fine
Does anybody now of this problem ? is there a solution?

This sounds like a call to the appropriate setter function is missing
in the FCD source XML wrapper section.
We’re essentially done with the 3.5.x series, trying very hard to
squash bugs to get 3.6.0 out, so if a fix for your problem does happen
shortly, it will show up in the 3.6.0 tarball (which means you’ll have
to upgrade.)

The generated python code looks right but there is definitely
something strange going on. I will take a look at it in the coming
days but if somebody has an idea don’t hold back
I think the parameters to the call to set_iq_corr() in the
section are reversed from the actual callback. Can you
test this:
diff --git a/gr-fcd/grc/fcd_source_c.xml b/gr-fcd/grc/fcd_source_c.xml
index 7c55239…1b83cba 100644

Yes, that’s the problem. I tested the modification and it works.

Ok, this is merged into maint->master. Since there will be a 3.5.3.2
release (sigh), the fix will be available for both 3.5 and 3.6.
thanks for the very quick reply and bugfix – it works for me editing
one line! Thanks!
