DRS6A noise Debug

[topcorner18]

Had not had a need to run my radar lately, however, last time out I fired it up and it was making much more noise than the normal rotational sound. It worked fine in terms of radar features, however, this new noise has me concerned. As part of debug, I would like to remove the antenna, open the clamshell and activate the radar so I can be nearby as it rotates to see if I can narrow down the noise source.

Before doing that I would like confirmation that it is ok to run it without the antenna and with the clamshell open.

Thanks

It is not okay to run a radar without an antenna or load. You will damage it. You might do a good visual inspection of the array where it meets the gearbox ensuring that sealant is swished out all around where they meet and that the bolts are entirely covered with sealant as required by the installation guidance. It might be water. If water it can cause issues not just with noise but also with radar returns. If you open the clamshell without running it, you can move the antenna array by hand back and forth to see if you hear any water.
