Re: [Tlf-devel] Few modifications in Tlf core

[Ervin Hegedüs - HA2OS]

Hello Thomas, hello Nate,

a few days ago I sent a patch to Nate (through this list) for
hamlib, to fix this bug in case of Kenwood rigs. May be he will
merge...

But I think the original problem will not solved with this,
namely I would like to keep untouched my filter state, when I
switch band/VFO. You _must_ to pass an explicit value to
rig_set_mode() as 4th argument, which is the filter width value.
That mean if you call that function, that set the state of
filter - except if you pass that value what actually set up.


73,


Ervin
