What is this signal in 33cm band?

What would be putting out a signal spanning so much bandwidth? Is this some device causing interference, or is it some form of spread spectrum transmission?

Looks like some EMF mixed with some birdies to me.

Birdies are usually focused on a narrow frequency, not across 1MHz of spectrum, aren't they?

That is the way they show up at least on HF bands.  I was getting birdies due to a bad network cable that showed up as thin solid lines on the waterfall.

Birdies aren't necessarily only over 1 MHz spectrum. There some times no rhythm or rhyme.

However, you aren't seeing spread spectrum transmissions from what I see. Sst usually will have a step looking effect in the water fall as it transitions between frequencies.

Plus in the waterfall the blips go almost across the entire 1.6 MHz of the band being displayed.

Personally, what I see are EMI burst at roughly. 4m,.5m,.1m,.4 apart. Maybe a power supply with bad shielding. Although I don't know any that run at that cycle rate. I once saw the processor of my computer showing up like that.
