Updated SDR CUBE Software

Sunday, February 5th, 2012

I have modified the latest SDR Cube software (1.06). This modification included an additional 100 Hz tuning rate and maximum internal CW keyer rate to 50 wpm.

The 100 Hz tuning rate allows you to tune across the band faster preventing stations from being missed at a higher rate of tuning. When you press the “Rate” button, there is an additional rate that you can select.

The internal keyer using the 1.06 software allowed 1 to 100 wpm. The dial was very sensitive when changing speeds. I don’t know of anyone that can send over 50 wpm with an iambic paddle. So for me this was impractical. I changed the speed to allow the internal keyer speeds of 1 to 50 wpm.

I have included a zip file containing the files that have changed from 1.06 release and the hex file needed to program the SDR-cube. See below:


Note:New softaware was just released, 1.08, that has this change and more. Please visit the SDR cube site for more information about this new release.

If you have any questions, please let me know.
