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? :-) 73, Igor, N1YX -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bruce Beford Sent: Saturday, May 21, 2011 12:47 PM To: [email protected] Subject: [Elecraft] KX3 RX IQ output question 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 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
