FreeDV Spectrum plot Issue

[Ray Butler]

I have an issue that Spectrum Plot tool stopped working about 2 months ago.  I don't see any trace at all, whether receiving voice or just noise on the frequency. Have been trying to troubleshoot it unsuccessfully thus far.

Windows 10.0.19045 Build 19045

FreeDV Version 2.3.0-dev-faff  (same issue observed on FreeDV 2.2.1 on this computer)

IC-7300 Versions:

Main CPU: 1.42

Front CPU: 1.01

DPS Program: 1.00

FPGA: 1.13

the Waterfall chart works fine, as do the Frm Radio, Frm Decoder and SNR plots.

FreeDV successfully decodes the digital Audio and I am able to transmit and be heard.

The "Level" bar is right around 1/4 when decoding.  

The spectrum plot works fine on my Windows 11 Laptop when connected to the same IC-7300.  

Looking for ideas or suggestions???

Thanks,
Ray

Hi Ray,

Any difference if you make the FreeDV window bigger or smaller? Also, is the Spectrum plot the only thing showing, or do you have other plots next to it?

Thanks,

Mooneer,

Thank you!  Reducing the window size caused the Spectrum plot to display.  It also works now for multiple windows when in the reduced size.  

Thanks!!

Ray
