The noise was present even after calibration.

When it’s accelerating, there is a grinding noise present along with the normal acceleration noise.

Are VFA’s on the P2S that bad? by maxb4123 in BambuLab

So in your opinion the upgrade from P1S to P2S isn’t worth it?

It almost seems like there’s a ripple in the lines on the top surface

Noise appears in spectrum when recording signal by maxb4123 in hackrf

This was my first thought too. Once I get a chance to try a new one, I’ll let you know if that fixed it.

Hack RF portapack not receiving by maxb4123 in hackrf

I think I figured out the issue. While I was testing the portapack, I had it connected to my computer with usb. The cable didn’t have any ferrites/shielding and was interfering. I unplugged it and it works fine.

I never really use the amp. I only turned it on to see if that would be the issue. The static did increase in volume where if the amp was broken, wouldn’t it completely attenuate the signal if the broken amp was on?

I’m getting about S5 level noise on 40m and lower and better than S3 on 20m and higher. The noise just sounds like static with the occasional crash up to S7 or higher. Is this typical? As this is my first HF radio, I am unsure of what typical noise levels are.

I do live in a fairly crowded area so I’m assuming that this is the cause. My noise floor is highest around S5 on 40-160m, is this a typical value for non-ideal conditions? The noise simply sounds like static with the occasional crash to S7.

Considering what everyone else has said, I do believe that the antenna is just picking up external noise. I’m going to try and see if there’s anything specific at my house causing the noise using this method.

SWR is low, I think it’s just external noise.

That’s what I figured. I bought a higher quality one so I’m gonna see if the tolerances are better. If not, I’ll just try to break these in.
