Helping someone with a 1935 setup today,,, They were getting some weak returns, so I checked the software settings and wasn't able to make much improvement with tuning/gain/sea/rain.
I opened the dome and was clean everywhere (no salt) no cracks in the antenna plastic... There was some brown dust in the waveguide interface between the electronics and antenna. I blew it off before I took a photo..
I shut the lid, spun the antenna a few times, opened it back and it remained clean. Turned it back on and got quite a bit better picture.
Any idea where this dust come from?
I'd assume it's something metal if it hurt the signal but it looked like espresso grounds.
