KerberosSDR • Turning off spectrum display

As I read - and it makes sense to turn off 'Spectrum Display' in order to reduce CPU load - improve performance. How about the DOA graphing(not phase differential calculations, but the DOA graph display cannot be turned off?) - is there a performance hit for continual plotting of the DOA graph?

After connecting you do Get data. Screen is then Logmag S11 & S21. The 2 curves are visible.
Then choose Chart format: VSWR S11. The screen is then blank. If you now click on the lower Auto (Y Min), the program will stop and with an error message:
"An unhandled exception has occurred in the application ...."
thanks for the report. I can reproduce this issue. You can avoid this error by setting higher Auto (Y Max) first. I will fix it soon.

Hello Erik ?
In our Radio Club we have different people with the NanoVNA. The NanoVNA extensions are more than welcome. The RESET with Calibration and the screen dump are especially useful. I did a quick test in Win10 and it works well. I only found one bug, but it was already in the previous version:

"An unhandled exception has occurred in the application ...."
"Axis object - the minimum value of the axis is higher than the highest value for a data point."
This error is always reproducible.
You must always close the Software and restart it.
This is a translation. I only have the error message in Dutch.

What is your issue? What is unstable in v3?

Troubleshooting Help • Re: HDSDR waterfall

Thanks Phil....I'm getting used to it myself, and you're right about it coming up from the spectrum display below. It's a slick program!

Troubleshooting Help • Re: HDSDR waterfall

I don't believe there an option to do that with HDSDR. In fact it's the main reason why i use it, the signals (to my eyes at least) look better flowing up from the spectrum section.

KerberosSDR • Re: Phase coherent IQ samples for a Windows program

Take a look at the Receiver @ https://github.com/rtlsdrblog/kerbeross ... eceiver.py

line 192 would be a good start I think.... #np.save("hydra_raw.npy",self.iq_samples)

Windows development - what's your goal?
