I wasn't getting that on my USB based Ozy. I did find that the behaviour was
sample rate and noise blanker setting dependent - if you selected too high a
sample rate it would stop functioning. With my RPI3 I was able to get 192K
samples per second, but with no NB selected; you needed a lower sample rate
with NB.

Is the behaviour you get affected by sample rate, NB, AGC etc selection?

Hi all,

Thanks John for a very nice piece of software. Just put it on one of my pi
3's running over RDP (latest production version). Listening to 40m as I
write this.  I have a basic Metis system so obviously running the 'old'
protocol. I do notice there is a rhythmic blip every 2-3 seconds which shows
as evenly spaced horizontal bars on the waterfall and a rise in the noise
floor on the spectrum. I don't get this with other software. Sounds like a
buffer alignment problem or if this is just me then anyone any idea what
might cause it.
