Taming the spikes

Post by VE3TMT »

Hi Darrin,

In your opinion, are there display settings to reduce the peaks across the display? I'm using the AvgB option on the display. Is there a way to slow the panadapter down or is what I'm seeing just noise around my QTH. I'm averaging about S4 of noise when this capture was taken.

I run my setup with AVGp, so I just avg the Pan and not the waterfall since I like to see the waterfall detail.

The timing of the AVG is under setup->display->Averaging time (I have mine set to 400ms)
but I also have the setup->display->FPS = 30 and the waterfall avg time = 30 and update = 30
and the analog refresh = 50 (for the analog meter needle movement)
I also have "hi-res Panafall" and "Avg Pan move" both ON
