That sounds like harmonics from the monitor oscillator. Are you running a
CRT monitor. If so, get an LCD monitor. That will get rid of the 15 khz
harmonics.

Hummmm. Every 15 KHz. Those are not DDS spurs, but probably interference
coming from something else external of the radio. A DDS spur will
disappear when you change the DDS (change frequencies).
What happens when you disconnect the antenna?

The biggest complaint I have about the 1000 is the amount of spurious
signals displayed in the higher bands. While the "SR"
button certainly moves them out of the way, it would be nice to hear
that the 3000 has improved upon this.
On my F3K on 20m, there is quite a bit of spurious shown on Panafall.
About every 15Kc
