SDC Skimmer for Flex Radios

Message from Yuri. I cannot find the user's question to which Yuri refers but hopefully they will see the answer here:

"Hi, Erik

I saw the correspondence in Flex-Community

If the user wants to see the call signs inside Pile-UP, you need to check the box:

I just tried loading the app and when I go to run it gives me a a message that VCRUNTIME140.dll was not found. I tried a few times to reinstall the program but no luck same message. Any ideas?

Erik Carling EI4KF

Assuming your OS is Windows 10 or 11: As a start, either install Microsoft Visual C++ Redistributable or, if already installed, repair it from control Panel. The dll you refer to is part is this package.

If this does not help, you may need to (re)register that dll.

Thank you for the information.

Good Morning. I am having an issue where the SDC skimmer is off frequency by about 2K. If I click on a callsign in SDC it takes me to the wrong frequency, and as I am tuning the radio the skimmer follows along but in the wrong place.

I am running a Flex 6400, SDC is using Smart SDR API client. Any ideas why this is happening?

Thanks 73 DE WB5SKM

Need more information.

What is mode: RTTY or CW or both? If RTTY, do you have SSDR in RTTY mode?

Is the Skimmer sample rate the same as SSDR (if not set both to 96000)?

kpaine

I am running Smart SDR on Windows 11. SDR is in RTTY mode. I am running Flex 6400 IQ Sample rate of 96000

I have not tested to see if this is happening in CW mode.

I am attaching some screenshots for better information

Thanks

I just checked the CW skimmer, and it is doing the same thing.

Thanks,

You might try the latest test version (. 3109)

My skimmer is spot on. no issues.

Thanks Rich, you win the prize. Latest version and a reboot have corrected the problem..Honestly did both at the same time so I am not sure which one corrected the issue.

Thanks 73

Glad to hear it. There have been a few issues recently which Yuri has quickly resolved. This "test versions" are always pretty safe so I always run those.

I had a ball using SDC with my 6600 in the CQWWDXRTTY over the weekend. The skimmer shows me stations I can hear (unlike telnet clusters) along with the ability to filter out non-mults and low point callsigns. I spent hours scrolling up and down the spotlist bandhopping and working 3 point mults exclusively. It was like "ducks on the pond". Every contact was S & P and there were no dead times! Yuri's software and Rich's Flex Connectivity Guide made working the contest a breeze, and Yuri's contest profile was spot on. It's too bad I wasn't able to devote more time this weekend. If you've hesitated to use SDC because it's a "work in progress", wait no longer.

This score may not impress you, but it was huge for me.

Hi!

Ken, your error is that you have selected the wrong audio device. For the skimmer you need an IQ stream, for example, DEFAULT: DAX IQ RX 1 (FlexRadio…)

Select the "SmartSDR API" control type. This will simplify control and avoid the problems of transmitting the IQ stream through audio channels.

Hi guys,

Is there anything special to do for the SDC CW Skimmer to have them to appear on the panadapter ?

They do not appear on my side.

Thanks

Erik Carling EI4KF

Is a possibility.

Otherwise, follow Yuri's manual or else this one:

Spots are enabled and I have the one from the telnet aggregator from SDC just not the skimmer ones.

Thanks for the link I will have a look.

Ok for those having the issue it is most probably the option which is by default at 0 under Verify call which is "Without CQ" as I was listening to a pile up there were no CQ…

Erik Carling EI4KF

Yes it could be that option. These are my settings in case they help at all.

F4BPO

Have exactly the same as you now and it works well
