The LP-Bridge software is now available, and that provides an extremely powerful environment for the K3 and the panadapter. For example, you can now run CW Skimmer and Writelog at the same time and have them share access to the K3.
Another example is to use your logging program (I use DXLab) together with PowerSDR and your K3. The LP-Bridge software allows you to share the serial port and work seamlessly: Click on a signal in PowerSDR and it changes the frequency on both the K3 and the logging software.
It's a new world out there!
