[Elecraft] [P3] REF LVL changes - normal behavior?

[Michael Gillen]

Hey guys, I am seeing this behavior on my P3 and am wondering if this is how it's supposed to work or or there is something wrong.

I set the REF LVL so I am just above the noise floor and then randomly a few minutes later either the floor goes way down or way up. In other words, I adjust the waterfall to show normal then randomly it will show nothing at all except the strongest peaks as if I adjusted the REF LVL way up or it shows a lot of noise as if I adjusted the REF LVL way down. So I have to keep an eye on it and constantly adjust the REF LVL. Its been doing this for the past 6 months or so it didn’t always do this.

The P3 is connected to my K3s which is having no problems. ATT is on, pre-amp off, AGC is fast.

Cheers!
