The last couple of weeks I've noticed the receive on my Uniden Madison acting peculiar. It's fine for one moment then it makes a kind of swishing sound as the needle on the meter drops down around 2 s units and as a result the receive gets quiet. I noticed this happens when it's windy outside. Although it's not windy today it has been raining. I thought it might have been the pl 259 on the antenna. I checked it and everything is tight. I thought it might have been the Madison itself but, i used the antenna switch to switch over to my Sonar which I use for am use. Same exact issue on the sonars receive After shutting the Madison off for a while then turning it back on I notice they receive is quite low until I key the microphone for the first time. I do use the Madison with an amplifier. The amp is a DNA Phantom. When I key the microphone for the first time I hear a relay click and then the receive comes back up. This doesn't solve the problem of my receiver jumping up and down as, it might be a different issue. After the first key down the relay I'm assuming opens and the receive comes back up. As I mentioned I think this is a different issue but, might be related to receive dropping up and down every few seconds. My antenna is an IMAX 2000 wit an MFJ 915 rf choke. I checked the pl 259's on the 915 and they were tight. I'm pretty sure one of you probably is familiar with this issue and might be able to point me in the right direction. Thank you.
