[Elecraft] SWL question

[Ron D'Eau Claire]

If you have the KBPF3 optional (general coverage) input filter installed,
you will have consistent reception from 500 kHz up through 30 MHz and again
across the 6 meter band (48 to 54 MHz). 

Note that the KBPF3 is a filter at the antenna input (not the I.F.) to
provide coverage in the gaps between the Ham bands. The K3 tunes the entire
range with or without out it, but sensitivity will suffer once you tune well
outside a Ham band without it since the 'stock' input filters are designed
to provide optimum performance only across the Ham bands.

I am an avid SWL'er and use the
K3 to listen to SW broadcast stations
and wefax. 

Somewhere posted are the curves
or ranges that the general coverage
receiver offers.  Im looking for
these posts - more info about the
general coverage receive option.

I hear that sometimes the general coverage
option shares low pass filters with the ones that
the option adds.

Take 25mhz WWV for example
or 6 mhz broadcast stations. My
question is what filter scheme is
employed for these frequencies
I have mentioned and what should
I expect rx wise in these ranges as
a result of that.
