HI all once again from ken in the UK,

After looking at the 'PDF' spec sheet I now think that the installed filters
are in the second IF and not roofing filter as I first thought.
I can only assume that the DSP will clean-up the filters in the third IF
stage.
I would have thought a radio of this calibre would have used 32 BIT DSP
filtering throughout ( with the exception of the roofing filtering in the
first IF stage ).
Sounds an interesting radio though, can't wait to buy one ( but I will have
to......hi )

All the very best to all, Ken, G4KIR.

The 'supplied bandwidths' mentioned by Universal certainly don't look
like
roofing filters but merely your run of the mill standard voice and CW
filters,
6, 3, 2.7, 1, 0.5 and 0.3 kHz.

Yes, that's why I wondered about the filters. The NRD-545 has lots of
them,
because they're in software really. From 10Hz to 10 kHz in 10 Hz steps!
