An update for SDR-Bridge V3 is available now at

Changes to SDR-Bridge include:
    • Improved updating of the display when changing stations.
    • Attempt to improve removing of CW Skimmer ghosts that interfere with proper startup. (Please let me know of any startup problems.)
    • The Quickstart guide has been updated. Thanks, Al NN4ZZ!

 For Skimmer Server and RTTY Skimmer Server users:

 The revamped v3.1 driver now will run both CW and RTTY skimmers simultaneously. To set this up:

 Configure each of the two skimmers for the number of desired bands. The total should not exceed the available channels.

    • Configure the two skimmers to use different telnet channels.
    • Make sure enough panadapters have DAX IQ assigned and are not active in the DAX app. (The DAX app doesn’t need to be running.)
    • In SmartSDR, if running multiple stations, assign PTT to the station you don’t want to run the skimmers. Typically SmartSDR running on a PC would host the skimmers with up to 4 channels, and a Maestro would be the PTT client. (If running on two PCs it is possible to have up to 6 skimmers. The setup currently requires a special filter.txt file. Let me know if you want to try that.)
    • Start the skimmers! Order doesn’t matter. (As usual the panadapter center frequencies will be locked for skimming.)

Thanks for improving the bridge.

I am not near my radio so cannot try. Here is a question. The last I tried it the panadapter was frozen to the center frequency and when I moved the frequency too far away, I did not have any visibility on the listening frequency. Panadapter and waterfall were showing a window that did not include the current slice frequency. Is that something that works differently now?

SDR-Bridge and CW Skimmer do not lock panadapters, and never have.

The Skimmer Server and RTTY Skimmer Server driver locks associated panadapters to a frequency designated by the host configutation files. Use an additional panadapter for your slices. for example, use SSDR panadapters for the skimmers, and Maestro for interaction.

There seems to be a problem launching the pDF CW Skimmer Quickstart guide.
