CW SKIMMER noise

Been trying to setup CW skimmer today to work with the CWT and found that I am getting a lot of noise. 

Is there something I can check to clean up the decoding. (see photo).image

    We how interesting.  How do I initiate a recalibration? I don't think I have seen that option. I'll give your recommendations a try,.

    Another thing worth checking is in the CW Skimmer audio settings.  You can choose between WDM and MME soundcard drivers.  I usually recommend MME but some folks have reported better results WDM.   When there is a noticable difference, it's usually related to corrupt drivers.  One setting will work while the other doesnt.  From the pictures above, I dont think this will help any, but it wont hurt either.

    In SSDR select 'Radio Setup' from the main menu.  Then choose the RX tab and press the 'Start' button.

    I don't know anything about CW Skimmer (I work at 35 wpm easily without tools), but it looks like receive noise, like from LED lighting.  I have broad-spectrum white noise all over the HF and VHF bands until I turn off my office LED lighting.

    Wondering if it's normal that the sampling rate of all my DAX audio devices in the sound control panel are set to 48,000 studio quality ? Should this be higher to match like 96000 sampling in my DAX IQ setting ?

    Both the record and playback IQ devices are set to 48khz by the installer. So I reset them to 96k since at 192k I got a blue screen !

    Will try this for a while.

    Found a lot of valuable CW SKIMMER configuration info in this document even though it is meant for SDR Bridge.  http://www.nn4zz.com/Data/NN4ZZ%20CwSkimmer%20Bridge%20setup%206-Dec-2018.pdf

    Excellent idea. I might take you up on that. I'm going to 'lean into' solving this properly on both computers this weekend.  I'm a fan of sharing help like that.

    One note FYI: For some reason, - Teamview has locked me out saying I was using it for commercial work. I wasn't but I did use it to 'receive' help from FlexRadio. 

    I moved all my locations and desktops to ANYDESK.com which is free. Honestly, it's faster and cleaner with no nagging to upgrade. Just fyi. 

    I'll be in touch.

    I will check that out "ANYDESK" . I did have that commercial usage nag also and ended up doing an unsinstall and registry cleanup... they re-installed it.  I see there is no private messenging on here. You can reach me at killeensteve @ gmail . com
