Choppy Audio?

I have gotten my SDR and DSD+ to decode digital. No Errors in the command prompt or anything, but the audio coming from the decode is sometimes very, very choppy. It's only sometimes, is there a bandwidth issue or what?

Likely a tuning error or incorrect gain setting (too low or too high).

I had a similar problem when I resurrected an old dongle that I wanted to use as a spectrum analyser. On testing on the local FM station, the audio had tiny gaps in it about every half second. After lots of fiddling I tracked it down to the FFT resolution for the display set too high - way up the top. I set it right down to 512, the audio was distorted but not chopped, so I gradually increased the resolution until I got the choppiness again and backed it off one step - it's now set on 16384 - I guess that's samples per second.
Don't tell anyone but I used SDRSharper :wink:

Have had the same problem in the past with choppy audio. Too many cobwebs in the brain but I think the problem was solved by changing the sampling rate. Don't quote me on this but I had the MSPS set too high and kept lowering it until problem solved. This will also affect the width of the spectrum.

Oh - here's one I do remember - make sure your squelch level is set properly. If set too high it'll cause that.
Check that first.

It can also be something as simple as too high to too low input volume on the audio cable.
