Since I got the GPs antenna it don't look like my system is showing on the map that much anymore. not sure if something got messed up or what.
Does the GPS part of the status page show that it got a fix? Does the blue LED flash once per second? Did the green LED near the GPS quit blinking? (either go out or stay on depending on the vintage of your board)
There should be a constellation map of satellites under the GPS area on the main page of the controller.

To clarify what is being asked for. Go to your browser and view the Blitzortung Controller webpage (should be 192.168.1.xxx) and log in so you can see your various settings and signal info. The LCD display on the controller board will you tell the correct IP address to use. Once you have that connection made, go to the Status tab and scroll down until you see the GPS section. It should look something like the attached screen capture I made on mine a few minutes ago. That display will tell you if your external antenna is working (or not) and how many satellites it is tracking.
Also, did you ever find a good ground to connect to? One of the best grounds, if you have access to it close by, is the ground for either your cable TV or Satellite dish companies ground connection.
Your signals still contain a significant amount of ripple on them indicating some kind of noise is getting into your amplifier via the power supply. I'm not sure what you are using for a power supply but there are many good, clean 5-v DC supplies available that have been written-up by Cutty. I'm using one of them and it has worked flawlessly for over a year now.
Make sure the leads from your antenna to your amplifier board are a short as possible. That will minimize extraneous noise
signal being picked-up at the inputs to the amplifier board.Good luck - you will get through this issue so don't give up!
