Typical loss of the 5- and 6-pole 200-Hz filters is about the same. I believe
we do have enough DSP-based gain compensation for all filter types, but I'll
ask our techs to verify this.
The noise figure of the radio is established ahead of the crystal filters, so
moderate loss in the filters
The 6-pole filters have an offset (like the 5-pole). The offset is clearly
marked on the filter and can be entered into the filter configuration page
using K3 Utility. This has no effect on performance.

Wayne indicated that they will but that matching is not critical when
used with the new

Wayne promised the comparison plot after they returned from Visalia
(starts today) and have a chance to recover.

The plots have a disclaimer that one can't compare the passband
attenuation for the filters.
Some of us have noticed that with the old 200 Hz 5 pole filters the
amount of gain available to compensate for it was not enough. I
observed that here by comparing SPECTROGRAM peak outputs per

Hi Wayne,
excellent! It will be helpful to all who wanted the old 5-poles/200Hz
obsolete option...
