sdr play and K3S
Locked
 
|
Hi Everyone.
I've been trying to get my SDRPlay (w/ SdrUno) to work with the IF output of my K3S. I've got OmniRig set up, so the K3S and SdrUno interact properly. Well, almost. There seems to be an offset between the K3S frequency and the SdrUno frequency. For example, I dial in WWV at 10 MHz on the K3S, and SdrUno hears the signal at ~9.875 MHz. On 80m, this offset is around 117KHz. I've tried the setting the External Converter offsets, that didn't help. In SdrPlay, I do have the IF Output Frequency set to 8125000 Hz and it is enabled. I've tried adjusting this value a little, and it didn't seem to help. I am aware of some of the limitations of SdrUno compared to other software, but this is the one that I'm used to. I may switch to another one at some point. Any ideas? I looked through the K3S config settings, and nothing jumped out at me. Thanks! 73, Don W7OXR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I’ve used the RSP-1a with HDSDR. I had to set the calibration for overall and then for each mode. Some values were + and some - . Also I found my SDR Play RSP-1a does drift noticeably.
Finall tossed the thing in the drawer and purchased a P3. Much more satisfactory.

Bob
I have been using the SDRPlay to drive Win4k3. It works with little problem. That problem is setting the global offset so that it matches exactly your K3s. Not all SDR software will play nicely being driven by the SDRPlay. And, BTW; If you are going to use narrows roofing filters, you are going to need to account for the fact that each has a slightly different calibration frequency. It's no big deal, but it should be set for your specific radio. 73, Barry K3NDM ------ Original Message ------ From: "Bob McGraw K4TAX" <[hidden email]> To: "Don Sayler" <[hidden email]> Cc: "Elecraft Reflector" <[hidden email]> Sent: 4/9/2020 9:42:53 PM Subject: Re: [Elecraft] sdr play and K3S >I’ve used the RSP-1a with HDSDR.
