Node-Red Based Active Frequency Adjust

Alan

I use both the Mac and Windows Smart SDR. One feature I like in Mac SDR is the ability to move the active frequency up and down in small and large increments. This is useful when you click on the panadapter to listen to a QSO but need some "fine-tuning" to put the active slice on the exact frequency.

I could not find the same on Windows SDR, so...I built one. The flow uses the WO2X Flex Radio Flow to subscribe to the slice status messages and to command the new slice frequency.

Here is a screenshot of the dashboard. There are two increments, "<" for 10 Hz and "<<" for 100 Hz.

For more information and to download the flow, go to the Ham Radio Node-Red io group.
