I have a setup where i run a preamp and 100 watt amplifier at my base station to try and reach some of the distant repeaters from here. Also i like to monitor 652 . Well i am getting a lot of noise when i run the preamp. It shows 20+ on the meter on my ic706. Making those distant signals very tough to copy. I have tried 2 different antennas. A 4 element beam and a 17 foot long verticle. But both the same situation. Now heres the thing. When it rains, the noise goes away. The static is reduced to 1 on the scale. Today it is raining and can copy those distant repeaters perfectly. I also have a ota tv antenna. Today same thing. The one station i get is coming in perfectly clear. But when it dries up again i know it will be back to the noise. What is going on here?
