Distorted Recorded Audio When Played Back Over The Air- 6400M
Happy Sunday Everyone!
I have had a consistent problem with choppy and distorted playback audio when I playback a recorded transmission over the air. I am recording using the SDR application. When I play back the audio locally at my machine, it is beautiful; however, when I play the recorded audio back to my friends, they tell me it is awful. This occurs whether I have DAX enabled or not.
My PC
Processor: AMD Ryzen 9 3900X 12 Core 3.80 Ghz
64 GB Ram
Windows 10 64 bit
I have made certain that my Level transmits between -5 to -10
I have also attached pictures of my task manager for CPU usage, Latency Monitor results, and DAX settings. Any advice would be much appreciated as this is becoming a headache lol.

Hi Wes, can you send a screen shot of SmartSDR so that we can see the RX equalizer and another so that we can see the TX equalizer? It is possible that you are overdriving things due to equalizer settings.

Thanks, Len for the help. Please see attached the pictures you requested. What is strange is that the recorded audio sounds beautiful when played back here locally at my machine.

Hi Wes, try turning off the TX equalizer. If you are listening to yourself via Full Duplex, also turn off the RX equalizer.
To hear your own signal, check out this YouTube video by Ken, NM9P:
I set my power down to 1 watt and transmit into a dummy load when I use this technique. Because I can't listen and talk at the same time, I use the record button on the receive slice.

I think it might be corrupted profiles.

@ka9ees Thanks Ed. With that being said, I am guessing it may help to delete current profiles and create new ones?

I would try that first. It's been a while since it happened to me. It was an earlier v3 though.
