 I found strange noise while I check my FreeDV signal from the Thetis with redpitaya.

FreeDV sends cat commands to the transceiver during transmission. While the Thetis receives them, it may stops processing signal. It is very short time, but that generates some noise. I have confirmed there is no noise without Cat. I think it is better to have checkbox for stop Cat during TX in the future version.

Hi Shingo,

Thanks for letting us know. There was a change previously that allowed frequency/mode to be retrieved by the application during TX which we thought didn't have side effects, but it looks like it does for at least some radios. To be safe, I'll go ahead and update the logic to no longer retrieve this during TX.

Thanks,

You should be able to select Mac as an option from https://netlogger.org/download.php. That's what shows up on my phone for me, anyway, once I force the desktop version of the website to appear.
