The most appropriate roofing filter is selected automatically as these
controls are rotated. If you have one of our [pending] variable-passband
crystal roofing filters installed, then the 1st I.F. bandwidth (crystal
filter) will closely track the 2nd I.F. bandwidth (DSP). This is far
superior to receivers that have only wide roofing filters and try to do
the whole job at the DSP, as well as receivers that simply shift one
filter against another at two different IFs.
I have been trying to avoid adding to the bedlam, but then you drop a mini-bomb
like this "pending" variable passband crystal roofing filter.
It would appear to be a good idea not to fill up the roofing filter slots until
this is no longer pending. I assume it will be similar to the K2 filters?
This is one of those little "gotcha's" that makes me wait until the dust settles
to order.
