I had an LP-PAN and sound card and could never get them to work very well (they're up for sale for anybody who's interested). I don't think I understand the whole RX-OUT/splitter/back to RF-in loop. Doing that would mean I would have no RX antenna connection, would it not? I use the RX IN connection for the feed from my K9AY loop in the back yard. If I used the RX-OUT port, wouldn't I then lose my lowband RX antenna?
This is all still very unclear to me. I don't mind buying the Win4K3 suite, but the COM port issues are confusing. 99% of the time I won't be using the Win4K3 software and associated control. It's only going to be used for CW contesting, period. The rest of the time I just use it as a conventional radio for CW, SSB, FT-whatever, and RTTY. - pjd -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Barry Sent: Thursday, May 23, 2019 9:10 PM To: Bob McGraw K4TAX <[email protected]>; [email protected] Subject: Re: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer You can do that. In fact I did that initially, I now use a Minicircuits Lab 2 way splitter and an about 6 db gain buffer amp between my K3s and the divider. This seemed to give me a bit better spectrum display. You will need NO SDR protection as you are using the receiver IF. I did use HDSDR during one of my early configurations. It just seemed harder to set up than what I use now. But, it won't require spending for an LP pan and sound card. Hmmm. I think I just got the answer to a question I had raised about using the I&Q data available from the K4 USB connector for CW Skimmer. I suspect the formats are the same. Your description at the bottom of your note will work if all you want is spectrum display, but to do serious integration like marrying up logging, spotting spectrum display CW skimmer and then a contest configuration, you are going to need to distribute and receive K3 band, frequency, and mode data. Using Win4K3 suite with com0com does make that easy and you could use what you describe using a pair of virtual ports. Should work well. 73, Barry K3NDM ------ Original Message ------ From: "Bob McGraw K4TAX" <[email protected]> To: [email protected] Sent: 5/23/2019 8:36:06 PM Subject: Re: [Elecraft] Connecting SDRPlay to P3 IF OUT, to CW Skimmer >Why not take the RX OUT of the K3 to a BNC T and the RX IN of the K3 to the other side of the BNC T and with a BNC T in that path, feed that to the SDR receiver. Then on the K3 press the RX ANT button and both are fed the entire band from the same antenna and they are protected during transmit. You can use HDSDR and OmniRig to control both the SDR receiver and control the K3. With HDSDR and OmniRig it communicates both ways. > >Two short BNC to BNC jumpers, a BNC T and a short BNC to the input on the SDR is all that is needed. > >73 > >Bob, K4TAX > > >______________________________________________________________ >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 ______________________________________________________________ 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
