[Elecraft] KX3 RX IQ output question

[Igor Kosvin]

Bruce,
What would be the point of tapping IQ after the roofing filter?
Somewhere in the posts I thought I read KX3 will use one BPF per band, so
the bandwidth probably will cover full band. After that you are at mercy of
your sound card.
Dual watch is in DSP. The IQ signals should come out before DSP, so the Dual
Watch has no bearing on IQ output.

By the way, with SDR and this DSP one probably could implement Triple or
Quadruple Watch. Question is: where to obtain more ears? :-)

Wayne, I know you don't have anything to do but answer questions... ;-)

I didn't get a chance to ask this last night during the KX3 webcast:

What will be the usable bandwidth of the RX IQ output? Since the dual watch
capability is described as +/- 10 KHz, I am wondering if this is the total
BW at this output jack. Also, will this be tapped off before the optional
roofing filter module?

Thanks in advance,
Bruce, N1RX
