Chris, tell me about the K2's filter selections in general terms.  The
KIO2 Programmer's Reference description of the FW command indicates that
setting to a specific bandwidth is not supported.  However, one of the
four filter slots may be directly selected.  Does every K2 have the same
four filters in the filter slots?  Or are the filters optional?  As the
only way to set the filter in K22 mode is by specific slot, how will the
backend know what these are if not fixed?

It would seem to me that for the way Hamlib works by passing a bandwidth
parameter in Hz to the backend that the K20 FW set command would work
the best.  Meanwhile, for reading the bandwidth the K22 FW query would
work the best.

So, with your K2 set for K20, how does the radio react when it receives
FW2500;, FW1000;, FW0500;, FW0100;, for example?

I'd like to be able to have the K2 set the appropriate filter when sent
a bandwidth in Hz, if possible.
