I used DL1YCF scripts to install PIHPSDR on both a RPi1 and RPi5.

RPi4 worked great didn't have to change a thing.

On the RPi5 I have signal that is way too high, noise floor is elevated.

On RPi4 GPIO is off in Make file but On is RPi5 version.

Could this be the issue?

I adjust it on the radio setup section under RX Gain Calibration to get the noise floor down. This is on a Rpi 4 though using ver 2.5.

I figured it out. If I do a reboot from menu it is way too much gain. A power reboot solves the issue, go figure!
